RESUMEN

BACKGROUND: Many consumers have a high salt intake and bread is a primary source because of its high rate of consumption. The inclusion of seaweeds has been proposed as an ingredient that could help reduce the salt content of food products. As such, the present study aimed to evaluate whether the amount of salt in bread could be reduced and the change in sensory properties be mitigated by the inclusion of brown seaweed. There were two different sensory trials conducted. In the first trial, participants (n = 102) evaluated bread made with brown seaweed (4% substitution for flour) with reduced amounts of salt (10%, 20%, 30%, 40% and 50%). The second trial asked participants (n = 98) to evaluate the control bread and the 20% salt-reduced bread in blinded and informed conditions. In both sensory trials, the breads samples were assessed using hedonic scales, just-about-right scales, and check-all-that-apply. RESULTS: The results showed that the 10% and 20% salt-reduced breads were acceptable and associated with being soft, chewy and having no aftertaste. The other breads were associated with a dense, dry and strong aftertaste, along with not being salty enough for the consumers. When the breads were evaluated in informed conditions, the salt reduction label had a negative impact on the consumers' liking. CONCLUSION: The research emphasizes that salt-reduced labels influence consumers' sensory perception. © 2023 The Authors.

RESUMEN

BACKGROUND: Kale and arugula are leafy green vegetables whose sensory properties have not been extensively explored. The objective was to assess the sensory properties and consumer acceptability of commercially available kale and arugula while also discovering drivers of consumer liking and barriers to consumer acceptance. Descriptive analysis and consumer testing were completed. The trained panellists (n = 11) were trained for 15 h to evaluate 11 sensory properties relating to the aroma, taste and texture of the kale and arugula. The consumer testing (n = 108) evaluated the leafy greens for overall liking and their liking of taste, aroma, texture and appearance. RESULTS: Results were analyzed using ANOVA, Tukey's HSD and external preference mapping. Approximately half of the attributes for the kale samples were found to be significantly different. Similarly, significant differences in sensory properties were found in most of the arugula samples. Consumers liked the kale and arugula varieties that were sweet and nutty. Also, they preferred arugula that was described as spicy. CONCLUSION: The majority of consumers preferred sweet and nutty leafy greens. Organic growing methods did not affect consumer liking; however, organic labels do positively affect hedonic ratings of a consumer's overall liking of the product. This study also identified that 'Baby' leafy greens are well liked by consumers, and this area of produce should be expanded. © 2021 Society of Chemical Industry.

RESUMEN

The glycaemic response of millet foods and the effect of processing are not known. Therefore, decorticated proso millet was used to produce four types of common food products (biscuits, couscous, porridge and an extruded snack). Postprandial blood glucose response of these products (all containing 50 g of total starch) was compared to the same foods produced with refined corn, in a crossover human study with 12 healthy male participants (age 26.3 ± 3.8 yr; BMI 23.3 ± 2.8 kg/m2). Capillary blood samples were collected and glycaemic response was determined; differences were assessed using repeat measures ANOVA. Overall, the mean (±SEM) incremental area under the blood glucose response curve (mmol min/l) of the proso millet products was different from the corn products, but individual products (couscous = 66.7 ± 11.6, biscuit = 82.6 ± 13.7, extrudate = 198.7 ± 20.9, porridge = 40.1 ± 5.8) were not significantly lower (couscous = 43.5 ± 5.8, biscuit = 102.0 ± 10.3, extrudate = 198.7 ± 20.9, porridge = 52.2 ± 8.1) (p > .05). Glycaemic response of the products was not dependent on the grain type, but rather product matrix.

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

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

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

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

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

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

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

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).

RESUMEN

Chemical irritants, like piperine, have the potential to increase human perception of tastes and odours, including saltiness. This cross-modal interaction could help the food industry develop new salt-reduced food products that maintain their salty taste. The objective of this study was: firstly, to determine the detection threshold of piperine (n = 72), secondly to evaluate piperine's influence on saltiness perception in model solutions (n = 78), and lastly to identify piperine's effect on sensory perception of low sodium soup using temporal check-all-that-apply (TCATA; n = 75). The group mean of the individual threshold was 0.55 ± 0.15 ppm. Piperine increased the saltiness perception of the model solutions, but it also increased the bitterness and decreased the sweetness of the solutions. The piperine significantly increased the saltiness intensity of the soups (evaluated using a generalized labelled magnitude), but during the TCATA task, the salty attribute was selected less for the soup with piperine than the control (based on the average proportion of selection). The TCATA indicated that the peppery attribute dominated the participants' perception of the soup with piperine. More studies are needed to assess piperine's cross-modal interactions.

RESUMEN

To reduce animal protein consumption, new food products need to be created. Furthermore, there is a growing number of consumers who consciously act to reduce their meat consumption. Hybrid meat products (HMP) are food items that combine both plant and animal proteins. The objective of this study was to create a hybrid meat burger (HMB) using yellow pea and chicken and to evaluate the sensory properties of the new product using static (check-all-that-apply [CATA]) and dynamic (temporal check-all-that-apply [TCATA]) methods. Yellow pea flour was added to a chicken burger at 0% (control), 10%, 20%, 30%, and 40%. A sensory trial asked participants (n = 69) to evaluate the HMBs using hedonic scales and CATA. A second sensory trial asked experienced panelists (n = 14) to evaluate the items using TCATA. The addition of the yellow pea flour decreased the liking of the burgers, except for the 10% formulation. The burgers made with higher amounts of yellow pea were associated with off-flavors (beany and nutty; significantly different from the control) during both CATA and TCATA tasks and detracted from consumers' liking. Juicy, moist, meaty, salty, and soft attributes increased the consumers' liking. The study identified that the addition of yellow pea to chicken burgers is only acceptable to consumers in small quantities (10%). In addition, the yellow peas contributed off-flavors and a dry texture that was disliked by the consumers. PRACTICAL APPLICATION: The environmental impacts of livestock production have created a need to incorporate more plant-based proteins into consumers' diets to increase sustainability. The market for meat alternatives, including hybrid meat products, is expanding; however, current products do not always meet consumers' expectations. Chicken is the fastest-growing meat sector in North America, and therefore this study's objective was to determine the sensory properties of a burger made from chicken and pulses (yellow pea). It was found that if 10% of chicken in a burger was substituted with yellow pea, then the sensory properties and consumer liking were not significantly affected.

RESUMEN

This study evaluated the acceptability of thickened ice cream with added whey protein to improve protein and fluid intake in long-term care (LTC) residents living with dysphagia and wounds. Two samples of ice cream were produced, the control sample of thickened ice cream, and thickened ice cream with added whey protein. The International Dysphagia Diet Standardization Initiative (IDDSI) Spoon Tilt Test assessed the consistency of the ice cream samples. A sensory trial asked participants (n = 56) to evaluate the samples for their liking of the appearance, texture, flavor, and overall liking using nine-point hedonic scales, followed by a check-all-that-apply question. The whey protein sample consistently passed the IDDSI Spoon Tilt Test whereas the control sample did not. The mean hedonic scores across all categories for both samples were not significantly different. The whey protein sample was associated with natural vanilla, creamy flavor, milk/dairy flavor, and buttery attributes which were important drivers of liking, and was not associated with the gumminess which decreased the liking. Findings indicate that whey protein addition to ice cream did not impact the acceptability of the thickened ice cream. This work is relevant to dietetic practice and those working in LTC as this ice cream will help improve quality of life by supporting wound management and safe swallowing. Furthermore, whey protein can be added to ice cream without negatively affecting its' sensory properties.

RESUMEN

Consumer interest in plant-based cheeses (PBCs) has increased in the last few years due to consumer concern for animal welfare, environmental impact, and health. In order to increase the acceptability of PBCs, sensory studies must be conducted. As such, the aim of this study was to evaluate the acceptability, sensory properties, and emotional responses to PBCs currently being sold in Canada. There were two different sensory trials conducted. In the first trial (n = 100), raw PBCs were evaluated, and in the second trial (n = 93) melted PBCs were evaluated. In both trials, five different PBCs were evaluated using nine-point hedonic scales, a check-all-that-apply (CATA) question, and the CATA variant of the EsSense25 profile. Participants were also asked to answer open-ended comment questions about PBCs. The results showed that participants thought PBCs are healthier than regular dairy cheese, but they did not like the flavour or textural properties of PBCs. PBCs that are buttery, smooth, and have soft attributes were preferred by the participants. Participants mainly disliked PBCs that were mouthcoating, rubbery, and had off-flavours. The PBCs with higher overall liking scores were associated with positive emotions.

RESUMEN

The prevalence of plant-based alternatives (PBAs) to meat in the marketplace has been increasing in recent years due to consumer demand. One of these plant-based products has aimed to mimic chicken products, specifically chicken nuggets. However, few sensory studies have been conducted on these products. The objective of this study is to evaluate the sensory properties, acceptability, and consumer perception of these PBAs. Participants (n = 105) were asked to evaluate five PBAs and a control (chicken nugget) using hedonic scales and a check-all-that-apply question. They also answered an open-ended comment question about PBAs. The participants separated the control from the PBAs in terms of their hedonic scores and sensory properties. They separated the PBAs based on their textural properties and if they had off-flavors. Participants disliked PBAs that were associated with an aftertaste, as well as beany, fibrous, and chewy attributes. The participants believed the PBAs currently on the market did not successfully mimic a chicken nugget and that improvement is needed, but they did believe PBAs are environmentally friendly.

RESUMEN

Plant-based milk alternatives (PBAs) are growing in popularity, which has led to the creation of many novel beverages from cereals, legumes, nuts, seeds, and pseudocereals. As such, the aim of this study was to evaluate consumer attitudes towards, and perception of PBAs currently offered on the market in Canada. First, a survey was conducted asking participants (n = 323) to complete a word association task investigating PBAs. Then six different PBAs (oat, almond, soy, pea, cashew, and coconut) were evaluated using nine-point hedonic scales and check-all-that-apply questions by consumers (n = 88). Lastly, consumers (n = 80) evaluated the acceptability of flavoured PBAs (chocolate and vanilla). Participants associated PBAs with health benefits, sustainability, and sensory characteristics. PBAs made from almond, oat, and pea were liked significantly more than PBAs made from cashews, but not more than coconut or soy PBAs. Perception of sweet, creamy, smooth, nutty, and white attributes increased the participants' liking of PBAs, while attributes such as aftertaste, brown, beany, watery, and off-flavour detracted from it. The flavouring (chocolate and vanilla) increased the participants' liking of almond and oat PBAs. Future studies should investigate other PBAs made from different ingredients and how flavouring can improve the acceptability of PBAs.

RESUMEN

Seaweeds are nutrient-dense marine organisms that have been proposed as a key ingredient to produce new functional foods. This study's first objective was to identify consumers' emotional responses and purchase intent towards a variety of food products containing seaweed. The secondary objective was to evaluate how hunger status and lifestyle affect consumers' emotional responses. Participants (n = 108) were asked to evaluate pictures of different food items containing seaweed (beef burger, cheddar cheese, fettuccine, fish filet, sausage, bread, yogurt, and dried seaweed) using the CATA variant of EsSense25 Profile® and a purchase-intent scale. The consumers also answered questions about their hunger status, food neophobia, food-related lifestyle, as well as open-ended comment questions about seaweed. Participants' purchase-intent scores were highest for bread and dried seaweed, which they associated with positive emotions. The participants disliked yogurt and sausage, indicating that they were disgusted with them. Participants believed seaweed could be added to fish, savoury, and cereal grains-based foods. The participants' hunger status as well as their food neophobia and lifestyle impacted their emotional responses. Future research should continue to investigate how emotions affect purchase intent, how participant's hunger status affects their emotions, and how participants' lifestyle changes how they perceive new food products.

RESUMEN

The global carbonated beverage market is large, and consumers like the oral irritation (ex. burning or prickling) associated with carbonated beverages. This study's first objective was to identify the effect of carbonation on consumers' liking and sensory perception of fruit juices (apple, cherry, and blueberry). The secondary aim was to evaluate consumers' emotional responses to carbonated fruit juices. The first trial asked consumers (n = 103) to use check-all-that-apply (CATA) and nine-point hedonic scales to evaluate six fruit juices (three carbonated and three non-carbonated). In the second trial, consumers (n = 107) were asked to evaluate the pictures of the same juices using the CATA variant of EsSense25 Profile® and a purchase intent scale. The consumers were also asked to identify what they like and dislike about carbonated beverages using an open-ended comment question. The first trial demonstrated that flavour significantly affected the overall liking scores but also identified that carbonation increased the overall liking of the blueberry and apple juices (p < 0.05). In the emotional response trial, the participants did not separate the samples based on carbonation, but rather separated the blueberry juices from the cherry and apple juices. The penalty lift analysis identified that when positive emotions were selected, the participants' purchase intent increased. Lastly, the consumers identified they like mouthfeel and flavour-enhancing qualities of carbonated beverages and associated them with special events. However, the participants disliked beverages that are too carbonated or flat and associated carbonated beverages with negative physical sensations and health perceptions. Overall, the flavour was more important than if the beverage was carbonated or not and purchase intent scores increased when positive emotions were perceived. Future research should investigate how emotions affect purchase intent, how participant's familiarity affects the emotions they select and evaluate how carbonation affects other beverages.
