Peganum spp.: A Comprehensive Review on Bioactivities and Health-Enhancing Effects and Their Potential for the Formulation of Functional Foods and Pharmaceutical Drugs.

The genus Peganum includes four species widely distributed in warm temperate to subtropical regions from the Mediterranean to Mongolia as well as certain regions in America. Among these species, Peganum harmala L., distributed from the Mediterranean region to Central Asia, has been studied and its phytochemical profile, traditional folk use, and application in pharmacological and clinical trials are well known. The review is aimed at presenting an insight into the botanical features and geographical distribution of Peganum spp. along with traditional folk uses. This manuscript also reviews the phytochemical profile of Peganum spp. and its correlation with biological activities evidenced by the in vitro and in vivo investigations. Moreover, this review gives us an understanding of the bioactive compounds from Peganum as health promoters followed by the safety and adverse effects on human health. In relation to their multipurpose therapeutic properties, various parts of this plant such as seeds, bark, and roots present bioactive compounds promoting health benefits. An updated search (until December 2020) was carried out in databases such as PubMed and ScienceDirect. Chemical studies have presented beta-carboline alkaloids as the most active constituents, with harmalol, harmaline, and harmine being the latest and most studied among these naturally occurring alkaloids. The Peganum spp. extracts have shown neuroprotective, anticancer, antimicrobial, and antiviral effects. The extracts are also found effective in improving respiratory disorders (asthma and cough conditions), dermatoses, and knee osteoarthritis. Bioactivities and health-enhancing effects of Peganum spp. make it a potential candidate for the formulation of functional foods and pharmaceutical drugs. Nevertheless, adverse effects of this plant have also been described, and therefore new bioproducts need to be studied in depth. In fact, the design of new formulations and nanoformulations to control the release of active compounds will be necessary to achieve successful pharmacological and therapeutic treatments.

Implementation of food safety management systems that meets ISO 22000:2018 and HACCP: A case study of capsule biotechnology products of chaga mushroom.

In our study, a food safety management system was developed for a chaga mushroom biotechnology product manufacturer, with the purpose of meeting the quality demands of customers and enhancing the manufacturer's reputation. The study focused on identifying the potentially significant hazards present at each stage of the production process for chaga mushroom capsule products, and on ensuring that the biotechnology company in question has fully implemented ISO22000:2018 and the HACCP methodology. The results indicate that, in the 1 year following the implementation of ISO 22000:2018, there was a statistically significant drop (P < 0.05) in the coliforms level of the tested biotechnology product samples that started in the ninth month following implementation. The rapid screening of mycotoxin, heavy metal, and pesticide residue levels also increased monitoring intensity and strengthened the periodic rotation plan, enabling control over potential problems relating to raw materials and ensuring product quality. This finding reveals the importance and necessity of rapid screening for small- and medium-sized food industry enterprises. Furthermore, 1 year after the system's implementation, the defect rate for chaga products was also observed to have declined, and the number of process flow anomalies requiring correction was also found to have decreased significantly (P < 0.05), indicating that safety and quality levels were improving and stabilizing. If implemented over a longer period of time, the food safety management system's benefits would stand out even more, and significant improvements would be observed for more monitored items. PRACTICAL APPLICATION: Few studies have touched on food safety management systems (FSMSs) developed for capsule health food products. The enterprise examined in this study had actively worked to improve its quality system and meet its customers' needs through the implementation of the FSMSs.

Potential Pharmaceutical and Food Applications of Postbiotics: A Review.

In recent decades, functional foods with ingredients comprising probiotics, prebiotics and postbiotics have been gaining a lot of attention from scientists. Probiotics and postbiotics are usually applied in pharmaceutical formulations and/or commercial food-based products. These bioactive agents can be associated with host eukaryotic cells and have a key role in maintaining and restoring host health. The review describes the concept of postbiotics, their quality control and potential applications in pharmaceutical formulations and commercial food-based products for health promotion, prevention of disease and complementary treatment. Despite the effectiveness of probiotic products, researchers have introduced the concept of postbiotic to optimize their beneficial effects as well as to meet the needs of consumers to provide a safe product. The finding of recent studies suggests that postbiotics might be appropriate alternative agents for live probiotic cells and can be applied in medical, veterinary and food practice to prevent and to treat some diseases, promote animal health status and develop functional foods. Presently scientific literature confirms that postbiotics, as potential alternative agents, may have superiority in terms of safety relative to their parent live cells, and due to their unique characteristics in terms of clinical, technological and economical aspects, can be applied as promising tools in the drug and food industry for developing health benefits, and therapeutic aims.

How probiotics face food stress: They get by with a little help.

The dietary consumption of probiotics in the form of pharmaceuticals or functional food can improve human health and contribute to disease prevention. However, the biological activity and health potential of food-delivered probiotics can be severely compromised by the stress conditions encountered by the microorganisms throughout the manufacture process, from probiotic preparation to their inclusion into food, subsequent storage and ingestion. Here, we give an account of the stress factors that can have major negative impacts on probiotic viability and functionality, with a focus on food-related environmental adverse conditions. We also describe some of the mechanisms elicited by the microbial cells to counteract these stresses and summarize a few relevant approaches proposed in literature to develop more robust and competitive probiotics by enhancing their stress tolerance, with the aim to improve the efficacy and health value of probiotic functional food.

[Evaluation of Safety Information of the Foods with Function Claims Based on Adverse Event Reports in Information System on Safety and Effectiveness for Health Foods Database].

Foods with Function Claims are allowed to label health claims based on scientific evidence evaluated by the manufacturers. To prevent health problems caused by inadequate use, the manufacturers should label proper safety information. To evaluate whether safety information is sufficiently provided, we conducted the adverse event review focused on popular functional ingredients using the database; Information system on safety and effectiveness for health food. The data suggested that causal factor of adverse events related to products containing soy isoflavone, ginkgo biloba extract and docosahexaenoic acid/eicosapentaenoic acid were overdose intake, concomitant use with certain medicines, and use by whom with an allergic predisposition. However, the safety information on the label was insufficient to prevent adverse events on each products' label. It is important not only to encourage food manufacturers to provide sufficient information based on safety review, but also to inform consumers about adverse events.

Nanoencapsulation of functional food ingredients.

Many functional food ingredients are poorly soluble in water, susceptible to chemical degradation, and incompatible with surrounding food matrix. Other issues are related to limited oral bioavailability, unpleasant sensory properties, and poor release profiles. Nanoencapsulation of functional food ingredients can help increase their water solubility/dispersibility in foods and beverages, improve their bioavailability by exhibiting good dose-dependent functionalities, mask undesired flavors/tastes to reduce the adverse effect on mouth-feel, enhance shelf-life and compatibility during production, storage, transportation and utilization of food products, and control release rate or specific delivery environment for better performance on their functionalities. This chapter provides an overview of different delivery systems for different functional food ingredients, the types of materials suitable for wall materials or building blocks of nanocapsules, the fabrication methods to assemble different delivery systems and release these active ingredients under different physiological conditions.

Systemic and skin-targeting beneficial effects of lycopene-enriched ice cream: A pilot study.

The health-promoting dietary antioxidant lycopene has limited natural bioavailability, but lycopene-rich functional foods can improve its bioavailability. We assessed a new lycopene-enriched ice cream for systemic antioxidant effects and influence on morphological characteristics of facial skin surface in healthy volunteers. In a randomized crossover study, we used 4-wk dietary interventions with either control or lycopene-enriched ice cream. Samples of serum and residual skin surface components (RSSC) from facial skin were taken before interventions, at 2 wk, and at intervention end. Lycopene concentration, conventional blood biochemistry, and oxidative stress biomarkers comprising inflammatory oxidative damage and low-density lipoprotein peroxidase proteins were assessed in the serum. Lycopene-associated immunofluorescence, lipid droplet size, corneocyte desquamation, and microbial presence were measured in the RSSC. The results show that lycopene concentrations in the serum and skin steadily increased during lycopene-enriched ice cream consumption. Whereas we found no intervention-dependent changes in conventional biochemical parameters, both inflammatory oxidative damage and low-density lipoprotein peroxidase protein values significantly decreased by the end of intervention with lycopene-enriched ice cream, but remained unchanged during control ice cream consumption. Control ice cream significantly increased corneocyte desquamation and bacterial presence in the RSSC. These adverse effects, which could potentially predispose consumers to acne development, were absent when volunteers consumed lycopene-enriched ice cream. We concluded that lycopene-enriched ice cream is a new functional food with clear antioxidant properties. In addition, enrichment with lycopene may alleviate proinflammatory action of ice cream at the level of facial skin, thus decreasing diet-associated acne development risk in young consumers.

Nutraceuticals and functional foods for the control of plasma cholesterol levels. An intersociety position paper.

Current evidence shows that cholesterol management either reduces the likelihood of cardiovascular disease (CVD) or slows down its progression. Hence, it is important that all health professionals make appropriate use of all the available intervention strategies to control risk factors: from dietary improvement and positive lifestyle changes to the use of functional foods, food supplements, and drugs. This review examines the effect of the most frequently occurring cholesterol-lowering substances in functional foods or in supplements across Europe, namely plant sterols and stanols, monacolin K found in red yeast rice, berberine and beta-glucans. We conclude that currently available supplements and functional foods can effectively reduce plasma LDL cholesterol levels by about 5 to 25%, either alone or in combination. Suitable candidates for these products are mainly individuals at low absolute cardiovascular risk at a young age or according to classic algorithms. Of note, despite being freely available for purchase, these products should be used following shared agreement between the physician and the patient ("concordance").

Claimed Effects, Outcome Variables and Methods of Measurement for Health Claims on Foods Related to Vision Proposed Under Regulation (EC) 1924/2006.

Adequate visual function has a strong impact on the quality of life of people. Several foods and food components have been hypothesized to play a role in the maintenance of normal visual function and in the prevention of eye diseases. Some of these foods/food components have been the object of a request of authorization for use of health claims under Articles 13(5) or 14 of the Regulation (EC) 1924/2006. Most of these requests have received a negative opinion from the European Food Safety Authority (EFSA) due to the choice of inappropriate outcome variables (OVs) and/or methods of measurement (MMs) applied in the studies used to substantiate the claims. This manuscript refers to the collection, collation and critical analysis of OVs and MMs related to vision. Guidance document and requests for authorization of health claims were used to collect OVs and MMs related to vision. A literature review was performed to critically analyse OVs and MMs, with the aim of defining their appropriateness in the context of a specific claimed effect related to vision. The results highlight the importance of adequate choices of OVs and MMs for an effective substantiation of claims related to visual function.

Development of functional agricultural products utilizing the new health claim labeling system in Japan.

In April 2015, Consumer Affairs Agency of Japan launched a new food labeling system known as "Foods with Function Claims (FFC)." Under this system, the food industry independently evaluates scientific evidence on foods and describes their functional properties. As of May 23, 2017, 1023 FFC containing 8 fresh foods have been launched. Meanwhile, to clarify the health-promoting effects of agricultural products, National Agriculture and Food Research Organization (NARO) implemented the "Research Project on Development of Agricultural Products" and demonstrated the risk reduction of osteoporosis of ß-cryptoxanthin rich Satsuma mandarins and the anti-allergic effect of the O-methylated catechin rich tea cultivar Benifuuki. These foods were subsequently released as FFC. Moreover, NARO elucidated the health-promoting effects of various functional agricultural products (ß-glucan rich barley, ß-conglycinin rich soybean, quercetin rich onion, etc.) and a healthy boxed lunch. This review focuses on new food labeling system or research examining functional aspects of agricultural products.

Effect of Extra Virgin Olive Oil and Table Olives on the ImmuneInflammatory Responses: Potential Clinical Applications.

BACKGROUND AND OBJECTIVE: Extra virgin olive oil (EVOO) is the common element among the Mediterranean countries. It can be considered a nutraceutical and functional food, thanks to its bioactive compounds. It can act and modulate different processes linked to ageing and age-related diseases related to a common chronic low grade inflammation. Depending on the cultivar, the growth conditions, the period of harvesting, the productive process and time of product storage, EVOO could contain different amount of vegetal components. Of course, the same is for table olives. METHODS: The aim of our review is to summarize the effects of EVOO and table olives on the immunemediated inflammatory response, focusing our attention on human studies. RESULTS: Our report highlights the effect of specific molecules obtained from EVOO on the modulation of specific cytokines and anti-oxidants suggesting the importance of the daily consumption of both EVOO and table olives in the context of a Mediterranean dietary pattern. In addition, the different action on immune-inflammatory biomarkers, are depending on the olive tree cultivar. CONCLUSION: Thanks to their bioactive compounds, EVOO and table olive can be considered as nutraceutical and functional foods. The beneficial effects analysed in this review will help to understand the potential application of specific olive components as therapeutic adjuvant, supplements or drugs.

Extra Virgin Olive Oil and Cardiovascular Diseases: Benefits for Human Health.

BACKGROUND AND OBJECTIVE: The cardioprotective properties of Mediterranean Diet were demonstrated for the first time from the Seven Country Study. In the last few decades, numerous epidemiological studies, as well as intervention trial, confirmed this observation, pointing out the close relationship between the Mediterranean diet and cardiovascular diseases. In this context, extra virgin olive oil (EVOO), the most representative component of this diet, seems to be relevant in lowering the incidence of cardiovascular events, including myocardial infarction and stroke. From a chemical point of view, 98-99% of the total weight of EVOO is represented by fatty acids, especially monounsaturated fatty acids such as oleic acid. Tocopherols, polyphenols and other minor constituents represent the remaining 1-2%. All these components may potentially contribute to "health maintenance" with their beneficial effects by EVOOO. METHODS: Studies that examined the effect of EVOO supplementation in healthy subjects and in individuals at cardiovascular risk were included. CONCLUSION: The studies analyzed demonstrated the role of EVOO as anti-inflammatory, antioxidant and vasodilatory nutrient that may contribute to lower the atherosclerotic burden.

Standardization of extract mixture of Chaenomeles sinensis and Phyllostachys bambusoides for anti-obesity by HPLC-UV.

JM-101 is a developed functional food formula using water extract of Chaenomeles sinensis and Phyllostachys bambusoides for anti-obesity. Standardization and quality control of herb mixture is more difficult than those of single herb. Additionally, the estimation of mixing ratio is an essential requirement for standardization. This study aimed to develop an efficient analytical method for the standardization of JM-101 based on C. sinensis and P. bambusoides. Protocatechuic acid and p-coumaric acid were selected as marker compounds of JM-101. A mixture of the two medicinal materials (1:1 w/w) was extracted by water and then liquid-liquid extracted (LLE) by ethyl acetate. The supernatant was evaporated to dryness and dissolved in methanol for analysis. The extraction time, material-to-water ratio and ethyl acetate-to-water ratio were optimized by multi-response optimization based on response surface methodology (RSM). The established methods were validated in terms of linearity, precision, accuracy, repeatability, stability and recovery. The novel method based on LLE and RSM provides a sensitive, accurate analysis and excellent extraction efficiency of marker compounds in JM-101, without interruption of other compounds in JM-101. In conclusion, the developed simultaneous analytical method contributes to the standardization of two materials (C. sinensis and P. bambusoides) and JM-101.

A comprehensive quality evaluation method by FT-NIR spectroscopy and chemometric: Fine classification and untargeted authentication against multiple frauds for Chinese Ganoderma lucidum.

The origins and authenticity against frauds are two essential aspects of food quality. In this work, a comprehensive quality evaluation method by FT-NIR spectroscopy and chemometrics were suggested to address the geographical origins and authentication of Chinese Ganoderma lucidum (GL). Classification for 25 groups of GL samples (7 common species from 15 producing areas) was performed using near-infrared spectroscopy and interval-combination One-Versus-One least squares support vector machine (IC-OVO-LS-SVM). Untargeted analysis of 4 adulterants of cheaper mushrooms was performed by one-class partial least squares (OCPLS) modeling for each of the 7 GL species. After outlier diagnosis and comparing the influences of different preprocessing methods and spectral intervals on classification, IC-OVO-LS-SVM with standard normal variate (SNV) spectra obtained a total classification accuracy of 0.9317, an average sensitivity and specificity of 0.9306 and 0.9971, respectively. With SNV or second-order derivative (D2) spectra, OCPLS could detect at least 2% or more doping levels of adulterants for 5 of the 7 GL species and 5% or more doping levels for the other 2 GL species. This study demonstrates the feasibility of using new chemometrics and NIR spectroscopy for fine classification of GL geographical origins and species as well as for untargeted analysis of multiple adulterants.

Desenvolvimento e avaliação nutricional de massas alimentícias ricas em fibras / Development and nutritional assessment of fiber-rich pasta

As mudanças socioeconômicas transformaram o perfil nutricional populacional, de desnutrição para obesidade. O consumo de massa alimentícia é uma das formas mais antigas de alimentação. Nesse contexto, o presente trabalho teve por objetivo a elaboração de um produto rico em fibras analisando sua composição nutricional e sua aceitabilidade. Foram elaboradas três formulações de massas alimentícias, sendo uma formulação padrão, uma com adição de brócolis e outra com brócolis acrescida de corante verde folha Tartrazina®. Realizou-se a análise bromatológica, sensorial e estatística. O resultado da análise das fibras apresentou 1,74% de fibra no macarrão integral e 1,46% no macarrão de brócolis. O macarrão que alcançou a preferência em todos os atributos foi o integral em cor natural. A massa alimentícia elaborada apresenta uma qualidade nutricional satisfatória com índices menores para o valor calórico, carboidratos, gorduras totais, colesterol e sódio, o que é recomendável a diversas patologias que necessitam da ingestão controlada desses nutrientes. Foi possível observar que a cor interferiu na aceitação do produto, pois o produto colorido obteve aceitação inferior ao alimento em cor natural.

Assessing the effects of different prebiotic dietary oligosaccharides in sheep milk ice cream.

The objective of this study was to assess the effects of different prebiotic dietary oligosaccharides (inulin, fructo-oligosaccharide, galacto-oligossacaride, short-chain fructo-oligosaccharide, resistant starch, corn dietary oligosaccharide and polydextrose) in non-fat sheep milk ice cream processing through physical parameters, water mobility and thermal analysis. Overall, the fat replacement by dietary prebiotic oligosaccharides significantly decreased the melting time, melting temperature and the fraction and relaxation time for fat and bound water (T22) while increased the white intensity and glass transition temperature. The replacement of sheep milk fat by prebiotics in sheep milk ice cream constitutes an interesting option to enhance nutritional aspects and develop a functional food.

Reviewing the Nutrition and Health Claims Regulation (EC) No. 1924/2006: What do we know about its challenges and potential impact on innovation?

Health claims potentially represent an opportunity for firms to engage in product differentiation and thereby induce investment into R&D and innovation in the food sector. The Nutrition and Health Claims Regulation (EC) No. 1924/2006 (NHCR) aims at protecting and promoting innovation as one of its objectives. However, existing studies indicate that this regulation may create several challenges for innovation in the food sector. To this end, we review the challenges related to the NHCR (Article 13.1) and its impact on innovation. Extant literature suggests that companies face challenges related to changing list of ingredients, missing transparency, wording of claims, limited financial resources, limited R&D resources, switching product categories and abandoning the functional foods sector. Moreover, current studies imply that so far the NHCR (in specific Article 13.1) does not seem to encourage innovation in the EU food sector.

Exploring the Nutrition and Health Claims Regulation (EC) No. 1924/2006: What is the impact on innovation in the EU food sector?

Literature suggests that despite its positive aim of promoting innovation, the Nutrition and Health Claims Regulation (EC) No. 1924/2006 (NHCR) may bring along several compliance challenges, which might affect innovation in the EU food sector. This study investigates the challenges faced by companies to comply with the NHCR (specifically Article 13.1) and their impact on innovation. To this end, we conducted an online survey with 105 companies involved in the EU food sector. Results indicate that companies perceive wording of claims, missing transparency and limited financial resources as major challenges to comply with the NHCR (Article 13.1). Companies reported not to have increased their R&D expenditure or innovation activities after the NHCR (Article 13.1) was implemented. Thus, this study highlights specific compliance challenges related to the NHCR (Article 13.1) and indicates that currently, the regulation does not seem to have fostered innovation in the EU food sector.

Quality properties of fruits as affected by drying operation.

The increasing consumption of dried fruits requires further attention on the quality parameters. Drying has become necessary because most fruits are highly perishable owing to their high moisture content and the need to make them available all year round and at locations where they are not produced. In addition to preservation, the reduced weight and bulk of dehydrated products decreases packaging, handling and transportation costs. Quality changes associated with drying of fruit products include physical, sensory, nutritional, and microbiological. Drying gives rise to low or moderate glycemic index (GI) products with high calorie, vitamin and mineral contents. This review examines the nutritional benefits of dried fruits, protective compounds present in dried fruits, GI, overview of some fruit drying methods and effects of drying operations on the quality properties such as shrinkage, porosity, texture, color, rehydration, effective moisture diffusivity, nutritional, sensory, microbiological and shelf stability of fruits.

[Methodological approaches to the creation of healthy food].

The substantiation of necessity of creation of healthy food products and their classification. Formulated methodological approaches to the creation of healthy food: enriched, functional and specialized purpose.
