RESUMEN

BACKGROUND: Flavour, texture, and extended shelf life are key quality traits for blueberries. Studies have used trained panelists and texture analysers to evaluate frozen blueberries. However, more studies are needed to investigate consumer perception and acceptance of frozen blueberries' texture. This study used word association, hedonic scales, and rate-all-that-apply to evaluate how consumers perceive the texture of frozen blueberries. RESULTS: Consumers were interested in the firmness of frozen blueberries, as well as crunchiness, softness, juiciness, and smoothness. They also identified the textural descriptors mushy, tough, chewy, squishy, and mealy. The participants separated the wild blueberries from the cultivated blueberries when evaluating their liking. Textural attributes were correlated with the consumers' overall liking (juicy, firm, crunchy, smooth positively and mushy, tough, squishy negatively). CONCLUSION: This study identified which textural attributes influence consumers' liking of frozen blueberries. Consumers preferred frozen blueberries that were firm, juicy and crunchy. © 2024 The Author(s).

RESUMEN

Sugar kelp (Saccharina latissma) has many nutritional benefits and has been identified as a rich source of fibre, vitamins, and antioxidants. However, it is not regularly consumed in the Western world, and the sensory perception of foods containing sugar kelp must be investigated to increase acceptance in North America. This study evaluated consumers' (n = 99) sensory perception of couscous with increasing amounts of sugar kelp (0% (control), 4%, 6%, 8%, and 10% wt/wt). Furthermore, consumers' purchase intent, liking, and emotional response to couscous with added sugar kelp was evaluated with and without nutritional information. Sugar kelp at 6% incorporation did not impact the consumers' liking scores ("Like Slightly" on the hedonic scale), but at 8% the consumers' liking significantly decreased ("Neither Like nor Dislike"). The 8% and 10% levels of sugar kelp addition led to astringency, bitter, hard, brackish, fishy, and chewy attributes being perceived by the consumers. The consumers identified they preferred samples that had soft, savoury, salty, and bland flavours and disliked samples that were brackish and gritty. The nutritional information did not increase overall liking scores, purchase intent, or emotional response. However, the inclusion of sugar kelp in the couscous did lead to an increased selection of positive emotions like happy, joyful, pleasant, and enthusiastic. Overall, the consumers were interested in foods containing seaweed and believed they were nutritious. The results indicated that sugar kelp could be added to couscous up to 6% wt/wt without impacting overall liking.

RESUMEN

Grape pomace (GP) is a waste product of the winemaking process and has been proposed as a nutritionally beneficial ingredient, as it contains phenolic compounds, dietary fiber, and antioxidant activity. It can be a polarizing ingredient due to its flavor components. Familiarity has been found to influence consumers' preferences and sensory perception of food. A sensory test was conducted to evaluate the acceptance, sensory perception, and emotional response to pasta sauces containing GP (3% [3GP], 6% [6GP], 9% [9GP] by volume and control without GP addition). The sensory trials included wine consumers (n = 44) and nonconsumers of wine (n = 58) to determine how consumers' familiarity with the flavor properties of GP influenced their perception of the pasta sauce. Overall, the addition of GP decreased the liking scores of the GP-containing sauces, but the wine consumers' hedonic scores for the control, 3GP, and 9GP were significantly higher than the nonconsumers. Both consumer groups identified that the samples with a higher amount of GP addition were associated with sour, bitter, astringency, grainy, and gritty attributes. However, the wine consumers used more positive emotions to describe their emotional response to the GP-containing samples. The study identified that GP led to off-flavors and textures in the pasta sauces. PRACTICAL APPLICATION: GP is currently a waste product, but it has many nutritional benefits. Consumers are increasingly looking for nutritional benefits from their food. When incorporated into pasta sauces, GP decreased the acceptance of the pasta sauce and negatively impacted the flavor and texture. Familiarity has been found to impact consumer acceptance, and wine consumers had a more positive emotional response and higher hedonic scores in response to the GP-containing pasta sauce than nonconsumers of wine.

RESUMEN

Consumers are interested in new sustainable ingredients but are unwilling to accept undesirable sensory properties in their food products. Luffa (Luffa cylindrica) is mainly harvested and processed for its fibrous network, which is used as an exfoliator, while its seeds are usually discarded. However, the seeds have been found to have various nutritional benefits. As such, this study investigated the sensory properties of luffa seed powder added to yogurt and compared it to other seed powder (flax, sunflower, chia, and hemp). Consumers (n = 107) evaluated their liking of the different seeds added to yogurt using hedonic scales and the sensory properties using check-all-that-apply (CATA). The luffa seeds when mixed with yogurt were associated with off-colour, off-flavour, metallic, strong flavour, bitter, salty, earthy and decreased consumer liking. The flax and sunflower seeds were found to be sweet, nutty, cooked, mild flavour, and to have a smooth texture. The overall liking scores for the flax and sunflower seed samples were significantly higher than the luffa and hemp samples. Future studies should investigate different drying and roasting treatments to improve the sensory properties of the luffa seeds.

RESUMEN

The seeds and sap of luffa [Luffa cylindrica (L.)] are usually discarded as waste. As such, this study aimed to identify the sensory properties of luffa sap (aqueous solution) and if it can be incorporated into a food item (orange juice) for added nutritional benefits and as an alternative sweetener. A sensory trial (n = 94) asked participants to evaluate a luffa sap sample and five different orange juice samples with increasing amounts of luffa sap (control [0%], 5%, 7.5%, 10%, 12.5%). The participants evaluated the samples using 9-point hedonic scales, check-all-that-apply, and an open-ended comment question. The luffa sap was described as having a mild flavor as well as woody, earthy, and floral attributes and an aftertaste. The liking scores for the orange juice with the 5% luffa sap did not significantly differ from the control. However, as the amount of luffa sap increased above 5%, the liking scores decreased and were significantly different from the control. The orange juice with luffa sap samples (7.5% and above) was associated with off-flavors, while the orange juice with 5% luffa sap and the control were associated with the attributes (sweet, fruity, orange, tropical, citrus) that increased the participants liking. Future studies should continue to investigate the sensory properties of luffa sap and its incorporation into different food products. PRACTICAL APPLICATION: This is one of the first studies to investigate the sensory properties of luffa sap with participants residing in the Western world. The luffa sap was found to be woody, earthy, bitter, and floral. It was acceptable to add luffa sap to orange juice up to 5% by volume. However, it did not increase the sweetness perception of the orange juice. At a 7.5% luffa sap addition and higher levels, off-flavors were observed in the orange juice.

RESUMEN

Background: The COVID-19 pandemic led to a multitude of immediate social restrictions for many across the world. In the UK, the lives of children and young people were quickly impacted when COVID-19 restrictions led to school closures for most children and restrictions on social interactions. The Born in Bradford COVID-19 longitudinal research study explored the impact of the COVID-19 pandemic on the lives of children and their families living in Bradford. Methods: Surveys were administered during the first wave of the pandemic (March to June 2020) and compared to findings from before the pandemic. The current study examined the social and emotional wellbeing of children from before to during the pandemic, measured using the parent completed Strengths and Difficulties questionnaire (SDQ). Regression analyses looked at associations between a range of social determinants of health and changes in SDQ scores. Results: The results showed that those children most likely to experience difficulties during the pandemic were boys, younger children, those from White British ethnicity (compared to Pakistani heritage children) and those living in the most deprived areas. There were associations between experiencing difficulties and: food insecurity; financial worry; getting below recommended levels of physical activity; and having less than the recommended amount of sleep. Conclusions: The effect of COVID-19 restrictions are likely to have had negative consequences on children that could, in time, have long-lasting impacts on the health, wellbeing and development of children in the UK.


The COVID-19 pandemic caused immediate and long-lasting social restrictions to be implemented here in the UK and across the world. In the UK, children and young people were quickly affected by these restrictions that led to school closures and other restrictions that prevented these individuals from socialising in person with one another. This study explored the impact that the pandemic had on the wellbeing of children by comparing data from before the pandemic with data collected during the pandemic. The data that has been collected looks at the behavioural strengths and difficulties that children are displaying. Our exploration found that children that were most likely to experience difficulties during the pandemic were boys, younger children, those who were White British and those who lived in the most deprived areas. The effect of the COVID-19 restrictions are likely to have had a negative impact on children and young people which in time may impact the health and development of children living here in the UK.

RESUMEN

Consumers have become interested in plant-based alternatives to animal-based products. One of the under-studied alternatives is plant-based eggs (PBEs). This research investigated PBEs relative to conventional eggs and tofu scramble-another plant-based alternative. Firstly, participants (n = 93) completed a word association task asking them about PBEs. Participants then evaluated the different food samples using hedonic scales, check-all-that-apply (CATA), and temporal check-all-that-apply (TCATA), as well as identified their emotional response and proposed use for PBEs. Participants were interested in plant-based alternatives, including PBEs, but they were concerned about the sensory properties. When they evaluated the different samples, the flavour and texture of the PBEs were disliked in comparison to the eggs. This result may be due to the beany, bitterness, and off-flavour attributes associated with the PBEs. Participants also associated the PBEs with negative emotions. The liking of tofu scramble was not significantly different from the eggs, and the eggs and tofu scramble were mainly associated with positive emotions. During the TCATA evaluation, the participants focused on the flavour attributes of PBEs, while their evaluation of the eggs was dominated by the textural attributes. Whether following a plant-based diet or not, consumers are interested in PBEs, but the sensory properties of PBEs need to be improved before they are willing to adopt them into their diet. This study is one of the first to evaluate the sensory properties of PBEs, as well as consumers' emotional response to them and their attitudes about PBEs.

RESUMEN

Infant Mental Health relates to how well a child develops socially and emotionally from birth to age three. There is a well-established link between parent-infant relationship quality, Infant Mental Health, and longer-term social and emotional development there is a lack of evidence-based interventions that support the parent-infant relationship and/or protect against poor Infant Mental Health. Little Minds Matter is a specialist Infant Mental Health service developed in Bradford (UK) to support parent-infant relationships by providing training and consultation for professionals and direct clinical work to families. The successful implementation of this intervention depends upon how well it becomes embedded within, or integrated into, the early years system. For the purposes of this study, the early years system includes health, social and education services that support child health and development from conception to primary school entry at age five. This study protocol aims to apply a systems approach to evaluate this service and provide a perspective on the process of embedding a complex service within a healthcare system. Multiple methods will be used to investigate embeddedness within the wider early years system. Routinely collected quantitative data about the service will be used to develop a system map showing interaction with related services. Qualitative data will be collected at two time points through interviews with individuals involved in the design and provision of the service, and professionals working within the early years system. Framework analysis will be used to analyse the data inductively and deductively within a systems approach. The findings from this study will provide evidence to inform the ongoing implementation of the service for providers and commissioning bodies. Exploring the application of a systems approach in this clinical context will have application more broadly for researchers evaluating complex interventions and services within a wider system.

RESUMEN

The number of consumers following plant-based diets has increased and in turn, the variety of plant-based foods available on the market has also increased. Many plant-based foods aim to mimic the functionality and sensory properties of conventional dairy products; however, they may not be suitable for specific populations. Dysphagia, for example, is a swallowing condition requiring texture-modified foods that meet specific criteria. While many conventional thickened products exist that are safe for individuals with dysphagia, the growing interest in plant-based eating alongside the increasing prevalence of dysphagia prompts a need for research on the use and safety of thickened plant-based alternatives. This study investigated the sensory properties of a thickened protein-enhanced ice cream (dairy and whey) compared to thickened protein-enhanced plant-based frozen desserts (cashew and pea, and coconut and pea). The formulations were evaluated using the International Dysphagia Diet Standardization (IDDSI) Spoon Tilt Test and a sensory trial (n = 104 participants, 47 flexitarians and 57 typical consumers) using static (hedonic scales and check-all-that-apply [CATA]), and dynamic (temporal check-all-that-apply (TCATA)) methods. The dairy and whey sample consistently passed the IDDSI test, while the plant-based samples did not. TCATA identified that the plant-based samples had an increased cohesiveness and adhesiveness, and decreased slipperiness when compared to the dairy and whey sample. The differences in textural properties may explain why the plant-based samples did not pass the IDDSI test. The study identified that although plant-based foods strive to mimic conventional dairy products, they have different textural and flavor properties.

RESUMEN

Obesity and obesity-related illness have become an increasingly prevalent problem and there is a critical need to combat this by reducing sugar, salt, and fat consumption. Due to this concern, the food industry has been developing salt-reduced foods, however, these products need to maintain their sensory appeal and flavors, which has proven to be a challenge. Grape pomace (GP), the solids left after pressing grapes for winemaking and consisting of grape seeds and skins, has been proposed as an environmentally friendly solution that can enhance the acceptability of salt-reduced food products. However, GP is associated with a large number of flavor compounds. As such, the objective of this research is to investigate the acceptability of GP addition in salt-reduced foods. Two trials were conducted using hedonic scales and temporal check-all-that-apply (TCATA) to evaluate tomato soup (n = 88) and vegetable juice (n = 99). Each trial included a control and sample containing grape pomace. The addition of the GP decreased the consumers' overall liking and the liking of the flavor, as well as increasing consumers' perception of saltiness intensity. The samples made with GP were associated with bitterness, sourness, and wine flavor during the TCATA evaluations. The study identified that GP increased saltiness perception, however, it also adds other flavors to the food product, which decreased the acceptability of the food items. PRACTICAL APPLICATION: There is a consumer demand to create salt-reduced foods that do not have altered sensory properties. Furthermore, consumers are interested in sustainable and environmentally friendly ingredients. Grape pomace is a byproduct of the wine industry and has been proposed as an ingredient that can increase the saltiness perception of food products. Grape pomace was added to tomato soup and vegetable juice to evaluate its effect on consumer acceptability and saltiness perception. The grape pomace did increase saltiness perception, but also added bitterness, sourness, and wine flavor to the food products.

RESUMEN

BACKGROUND: Welfare advice services co-located in health settings are known to improve financial security. However, little is known on how to effectively evaluate these services. This study aims to explore the feasibility of evaluating a welfare advice service co-located in a primary care setting in a deprived and ethnically diverse population. It seeks to investigate whether the proposed evaluation tools and processes are acceptable and feasible to implement and whether they are able to detect any evidence of promise for this intervention on the mental health, wellbeing and financial security of participants. METHODS: An uncontrolled before and after study design was utilised. Data on mental health, wellbeing, quality of life and financial outcomes were collected at baseline prior to receiving welfare advice and at three months follow-up. Multiple logistic and linear regression models were used to explore individual differences in self-reported financial security and changes to mental health, wellbeing and quality of life scores before and after the provision of welfare advice. RESULTS: Overall, the majority of key outcome measures were well completed, indicating participant acceptability of the mental health, wellbeing, quality of life and financial outcome measures used in this population. There was evidence suggestive of an improvement in participant financial security and evidence of promise for improvements in measured wellbeing and health-related quality of life for participants accessing services in a highly ethnically diverse population. Overall, the VCS Alliance welfare advice programme generated a total of £21,823.05 for all participants, with participants gaining an average of £389.70 per participant for participants with complete financial outcome data. CONCLUSIONS: This research demonstrates the feasibility of evaluating a welfare advice service co-located in primary care in a deprived and ethnically diverse setting utilising the ascribed mental health, wellbeing and quality of life and financial outcome tools. It provides evidence of promise to support the hypothesis that the implementation of a welfare advice service co-located in a health setting can improve health and wellbeing and reduce health inequalities.

RESUMEN

Consumers are adding collagen powder to their diets for its health benefits. However, few studies have investigated consumer perception of collagens produced from different sources. As such, the objective of this study was to evaluate the acceptability and sensory properties of commercially available collagen powders (bovine, marine, and mixed). Two different sensory trials were conducted. First, six different collagen powders were mixed with water and evaluated for their sensory properties and acceptability (n = 98; referred to as collagen-in-water). In the second trial, the collagen powders were mixed into strawberry smoothies and their sensory properties were assessed (n = 92; referred to as collagen-in-smoothie). Both studies used the 9-point hedonic scale and check all that apply to evaluate the collagen powders. The results indicated that the collagens could be grouped based on their source when evaluated in water and in a smoothie. Also, the aroma and taste of the marine collagens impacted their acceptability and were associated with fishy, sour, bitter, and salty attributes. Overall, collagen that was low in flavor was more acceptable to the participants in this study. PRACTICAL APPLICATION: Recently, consumers have begun to purchase collagen powder for its health benefits, specifically its positive effects on skin appearance. Understanding the sensory properties of the different collagens can allow for the ingredients to be incorporated into different food products and help promote consumer purchases. Collagen should be mixed into beverages rather than be consumed in water alone to increase acceptability. Also, marine collagen incorporation into foods should be avoided unless off-aromas and flavors can be masked by other properties.

RESUMEN

INTRODUCTION: Women from social disadvantage are at greater risk of poor birth outcomes. The midwife-led continuity of care (MCC) model, which offers flexible and relational care from a small team of midwives, has demonstrated improved birth outcomes. In the general population, the impact of MCC on socially disadvantaged women and on birth outcomes is still unclear. This protocol describes a pragmatic evaluation of the MCC model in a socially disadvantaged population. METHODS AND ANALYSIS: An open-labelled individual prospective randomised controlled trial with an internal pilot, process evaluation and economic analysis, from 1 April 2022 to 31 March 2024.Women will be randomly allocated to MCC or standard care as part of usual midwifery practice. Participants and midwives will not be blinded, but researchers will be. An internal pilot will test the feasibility of this process.Participants are those randomised into MCC or standard care, who consent to participate in one of two Born in Bradford (BiB) birth cohort studies. Outcomes are taken from routinely linked health data, supplemented by additional data capture. The sample size is fixed by the capacity of MCC teams, commissioning duration and numbers recruited into the cohort. The estimated maximum fixed sample size is 1,410 pregnancies (minimum 734).Intention to treat (ITT) analysis will be undertaken to assess the impact of MCC on two independent primary outcomes. An economic evaluation will explore the impact on health resource use and a process evaluation will explore fidelity to the MCC model, and barriers/facilitators to implementation from midwives' and women's perspectives. ETHICS AND DISSEMINATION: Ethical approval has been obtained for the randomisation in midwifery practice, use of the cohort data for evaluation and for the process evaluation. Findings will be published in peer-reviewed journals, presented at conferences and translated into policy briefings. TRIAL REGISTRATION NUMBER: IsRCTNhttps://doi.org/10.1186/ISRCTN31836167.

RESUMEN

Thickened soup formulations were created with different proteins (hemp, soy, pea, and whey) to improve protein and fluid intake. The formulations consisted of a control soup, and soups with 6% whey protein, 6% hemp protein, 6% pea protein, and 6% soy protein by volume. The suitability of the samples for those living with dysphagia was evaluated using the international dysphagia diet standardization initiative (IDDSI) spoon tilt test and a sensory trial (51 older adults and 51 younger adults). The sensory trial used nine-point hedonic scales and check-all-that-apply to evaluate the different formulations. The sample with the whey addition was not significantly different than the control in terms of liking of flavor and texture, but it decreased the participants' overall liking. The hemp, pea, and soy decreased overall liking as well as liking of flavor and texture. They were associated with off-flavors, aftertaste, and astringency. The responses from the older and younger adults were compared and significant differences were found in their liking of the texture, with the older adults finding the formulations' texture significantly more acceptable. Overall, the study identified that hemp, pea, and soy did not create acceptable thickened soup formulations and the hemp and pea formulations did not achieve a consistency level that is acceptable for those living with dysphagia.

RESUMEN

Subjective social status is how a person perceives their social class relative to other people and has frequently been associated with people's health and well-being. A frequently used measure of subjective social status is the MacArthur Scale of Subjective Social Status that depicts social status as a 10 rung ladder, asking individuals to rank themselves on this ladder relative to other people, either in their local neighbourhood or wider society. The Born in Bradford's Better Start birth cohort study aims to understand the lives, relationships, wellbeing, and social and economic circumstances of pregnant women and their children in three inner city areas of Bradford, UK. Pregnant mothers were asked to report their subjective social status, using the MacArthur subjective social status scales, comparing themselves to other people in their local neighbourhood and in England as a whole. This paper explores the characteristics of the women who gave responses, examines associations between the MacArthur subjective social status measures and other subjective and objective measures and looks specifically at the characteristics of women who reported either very low or very high subjective social status. On average, women reported that they had a higher social status compared to others within their local neighbourhood (mean ladder rung = 6) and, although participants were from areas of Bradford with very high levels of deprivation, 23% placed themselves on the top three rungs, 8-10. Respondents reported that they had an average social status when comparing themselves to people in all of England (mean ladder rung = 5) and 13% placed themselves on the top rungs 8-10. These findings raise important questions about the interpretation of the MacArthur scale of subjective social status.

RESUMEN

Consumers are interested in plant-based alternatives (PBAs) to dairy and meat products, and as such, the food industry is responding by developing a variety of different plant-based food items. For these products to be successful, their textural properties must be acceptable to consumers. These textural properties need to be thoroughly investigated using different sensory methodologies to ensure consumer satisfaction. This review paper aims to summarize the various textural properties of PBAs, as well as to discuss the sensory methodologies that can be used in future studies of PBAs. PBAs to meat have been formulated using a variety of production technologies, but these products still have textural properties that differ from animal-based products. Most dairy and meat alternatives attempt to mimic their conventional counterparts, yet sensory trials rarely compare the PBAs to their meat or dairy counterparts. While most studies rely on consumers to investigate the acceptability of their products' textural properties, future studies should include dynamic sensory methodologies, and attribute diagnostics questions to help product developers characterize the key sensory properties of their products. Studies should also indicate whether the product is meant to mimic a conventional product and should define the target consumer segment (ex. flexitarian, vegan) for the product. The importance of textural properties to PBAs is repeatedly mentioned in the literature and thus should be thoroughly investigated using robust sensory methodologies.

RESUMEN

There is an increasing demand for plant-based alternatives by individuals living in the Western world. One of the newer plant-based alternatives is plant-based fish and seafood (PBFs). This study aimed to investigate individuals' opinions and attitudes toward PBFs, as well as evaluate the effect of involvement in the fishing industry on the participants' attitudes. Participants (n = 183) were asked to answer questions about their perceptions of PBFs. Participants believed that PBFs were environment-friendly and were interested in trying PBFs but were concerned about the taste and texture of PBFs. Although participants were likely to try PBFs, they were less likely to add them to their regular diet. After reading messages about the benefits of PBFs in this study, participants' willingness to try PBFs and add PBFs into their regular diet increased. In addition, those who worked in the fishing industry or had high food neophobic scores did not believe that PBFs would taste like conventional fish and seafood products. Future studies should investigate the attitudes of individuals living in different regions and investigate whether exposure to PBFs affects consumer perceptions of the food product. PRACTICAL APPLICATION: Consumer demand for new plant-based products is increasing, but before new products can be released, participants' attitudes and perceptions need to be evaluated. Plant-based alternatives to fish and seafood are a new food product, and therefore, participants' attitudes toward them need to be investigated. It was found that the individuals were more willing to try plant-based fish and seafood. In addition, they were more likely to incorporate them into their diet after reading about the nutritional benefits and sustainability of PBFs.

RESUMEN

Subjective social status measures a person's perception of their social class relative to other people and has theoretically and empirically been positively associated with health and wellbeing. A widely used measure of this construct is the MacArthur Scale of Subjective Social Status, which asks people to report their social status by placing themselves on a ladder which represents the social hierarchy of their society or community; the scale has been used with many different populations across many countries. In this research note, we describe two cases where we encountered unexpected reactions to the MacArthur Scale that we believe highlight (a) the salience of relative social status for people's wellbeing in contemporary society and (b) the concomitant sensitivities raised by measuring this subjective experience. We discuss the implications of these observations for future research.

RESUMEN

Existing research has shown that daily hassles are associated with increases in between-meal snacking, often resulting in the increased consumption of high sweet and high fat foods. However, it is currently unclear whether the presence of daily uplifts may buffer the negative effects of daily hassles on unhealthy eating behaviour. Therefore, the current study explored the main and interactive effects of daily hassles and daily uplifts on snacking behaviours in adults. One hundred and sixty participants (M age: 23.69 years) reported their daily hassles, daily uplifts and snacking behaviours over the preceding 24 hour period. Participants' emotional eating style was also measured. Using moderated regression analysis, the daily hassles x daily uplifts interaction was found to be statistically significant for both total snack and unhealthy snack consumption. Simple slopes analyses showed that the relationship between daily hassles and snacking was weaker and non-significant at higher levels of daily uplifts compared to moderate and lower levels. The current study provides novel evidence that daily uplifts may act as a buffer against the negative impact of daily hassles on food consumption.

RESUMEN

Ice cream formulations with varying amounts of added whey protein were created for those living with dysphagia in long-term care facilities (LTCs) to improve protein and fluid intake. The samples of thickened ice cream included a control (0% whey protein [WP]) and formulations with 6% (6WP), 8% (8WP), 10% (10WP), 12% (12WP) and 14% (14WP) added whey protein by volume. The consistency of the samples was assessed using the International Dysphagia Diet Standardization Initiative (IDDSI) Spoon Tilt Test, a sensory trial (n = 102) using hedonic scales and check-all-that-apply (CATA) and another sensory trial (n = 96) using temporal check-all-that-apply (TCATA). The whey protein increased the acceptability of the thickened ice cream except for the 12WP and 14WP formulations. The formulations with higher amounts of whey protein were associated with bitterness, custard/eggy flavor, and mouthcoating. The TCATA identified that the addition of whey protein led to slippery, gritty, and grainy attributes being perceived in the thickened ice cream. The study identified that 10% whey protein by volume can be added to thickened ice cream without impacting its' acceptability and the 6WP, 8WP, and 10WP formulations were liked significantly more than the control (without whey protein).
