The current use and evolving landscape of nutraceuticals.

The nutraceutical market is currently a high-impact multi-billion-dollar industry, and it is anticipated to grow rapidly over the next decade. Nutraceuticals comprise diverse food-derived product categories that have become widespread due to increased consumer awareness of potential health benefits and the need for improved wellness. This targeted review is designed to identify the current global trends, market opportunities, and regulations that drive the nutraceutical industry. Safety and efficacy concerns are also explored with a view to highlighting areas that necessitate further research and oversight. Key drivers of the nutraceutical market include aging populations, consumer awareness, consumer lifestyle, increasing cost of healthcare, and marketing channels. Although some nutraceuticals hold promising preventive and therapeutic opportunities, there is a lack of a universal definition and regulatory framework among countries. Moreover, there is a lack of adequate evidence for their efficacy, safety, and effectiveness, which was even further highlighted during the ongoing coronavirus pandemic. Future prospective epidemiological studies can delineate the health impact of nutraceuticals and help set the scientific basis and rationale foundation for clinical trials, reducing the time and cost of trials themselves. Together, an understanding of the key drivers of the nutraceutical market alongside a consistent and well-defined regulatory framework will provide further opportunities for growth, expansion, and segmentation of nutraceuticals applications.

Examining the Prevalence, Nutritional Quality and Marketing of Foods with Voluntary Nutrient Additions in the Canadian Food Supply.

Foods with voluntary nutritional additions are a fast-growing sector of the global food industry. In Canada, while the addition of nutrients to foods has been regulated through fortification regulations, parallel policies which aim to encourage product innovation have also allowed for the voluntary addition of nutrients and other novel ingredients to 'supplemented' and 'functional' foods. Concerns have been raised that the consumption of these products may have negative repercussions on population health, such as high nutrient intakes inappropriate for certain population subgroups (e.g., children) and the shifting of dietary patterns to include more unhealthy foods. The aim of this study was to evaluate the prevalence, nutritional quality, and marketing characteristics of foods with added nutrients in the Canadian market. We found many nutritionally-enhanced foods contained high levels of nutrients beyond recommended intakes, despite these nutrients having no evidence of inadequacy in the Canadian population. Additionally, a large proportion of foods with added nutrients had poor nutrient profiles (were deemed 'less healthy' than their non-enhanced counterparts) and carried heavy marketing on their labels, regardless of their nutritional quality. Taken together these findings raise concerns about foods with voluntary nutrient additions and suggest the need to further investigate consumer attitudes and decision-making towards these foods.

Astaxanthin for the Food Industry.

Xanthophyll astaxanthin, which is commonly used in aquaculture, is one of the most expensive and important industrial pigments. It is responsible for the pink and red color of salmonid meat and shrimp. Due to having the strongest anti-oxidative properties among carotenoids and other health benefits, natural astaxanthin is used in nutraceuticals and cosmetics, and in some countries, occasionally, to fortify foods and beverages. Its use in food technology is limited due to the unknown effects of long-term consumption of synthetic astaxanthin on human health as well as few sources and the high cost of natural astaxanthin. The article characterizes the structure, health-promoting properties, commercial sources and industrial use of astaxanthin. It presents the possibilities and limitations of the use of astaxanthin in food technology, considering its costs and food safety. It also presents the possibilities of stabilizing astaxanthin and improving its bioavailability by means of micro- and nanoencapsulation.

Energy, Sugars, Iron, and Vitamin B12 Content of Commercial Infant Food Pouches and Other Commercial Infant Foods on the New Zealand Market.

There has been an important shift in the New Zealand infant food market over the past decade, with the majority of complementary foods now sold in "pouches". Along with the increasing market share of commercial infant food pouches internationally, there have been growing concerns about their nutritional quality. However, research examining the nutritional quality of these pouches compared to other forms of commercial infant foods in New Zealand has not been undertaken. Nor have any studies reported the free sugars or added sugars content of these foods. To address this knowledge gap, a cross-sectional survey of infant foods sold in New Zealand supermarkets was conducted in 2019-2020. Recipes and nutrient lines were developed for the 266 foods identified (133 food pouches). The energy, iron, vitamin B12, total sugars, free sugars, and added sugars content of infant food pouches and other forms of commercial infant foods per 100 g were compared, both within food groups and by age group. Infant food pouches contained similar median amounts of energy, iron, and vitamin B12 to other forms of commercial infant foods but contained considerably more total sugars (8.4 g/100 g vs. 2.3 g/100 g). However, median free sugars and added sugars content was very low across all food groups except for "dairy" and "sweet snacks". All "dry cereals" were fortified with iron whereas none of the infant food pouches were. Therefore, consuming food pouches to the exclusion of other commercial infant foods may place infants at risk of iron deficiency if they do not receive sufficient iron from other sources.

Pigments and vitamins from plants as functional ingredients: Current trends and perspectives.

The food manufacturing industry has increasingly focused in the development of wholesome and safer products, including certified labeled "super foods," "healthy foods" and "functional foods," which are currently under great demand worldwide. Plant pigments and vitamins are amidst the most common additives incorporated to foodstuff, not only for improving their nutritional status but also for coloration, preservation, and even therapeutic purposes. The recovery of pigments from agro industrial wastes using green emerging approaches is a current trend and clearly the best alternative to ensure their sustainable obtainment and make these ingredients more popular, although still full of challenging aspects. Stability and bioavailability limitations of these active molecules in food matrices have been increasingly studied, and a number of methods have been proposed to minimize these issues, among which the incorporation of a co-pigment, exclusion of O2 during processing and storage, and above all, microencapsulation and nanoencapsulation techniques. The most recent advances and challenges in the application of natural pigments and vitamins in functional foods, considering only reports of the last 5 years, were the focus of this chapter.

Potential Industrial Applications and Commercialization of Microalgae in the Functional Food and Feed Industries: A Short Review.

Bioactive compounds, e.g., protein, polyunsaturated fatty acids, carotenoids, vitamins and minerals, found in commercial form of microalgal biomass (e.g., powder, flour, liquid, oil, tablet, or capsule forms) may play important roles in functional food (e.g., dairy products, desserts, pastas, oil-derivatives, or supplements) or feed (for cattle, poultry, shellfish, and fish) with favorable outcomes upon human health, including antioxidant, anti-inflammatory, antimicrobial, and antiviral effects, as well as prevention of gastric ulcers, constipation, anemia, diabetes, and hypertension. However, scale up remains a major challenge before commercial competitiveness is attained. Notwithstanding the odds, a few companies have already overcome market constraints, and are successfully selling extracts of microalgae as colorant, or supplement for food and feed industries. Strong scientific evidence of probiotic roles of microalgae in humans is still lacking, while scarce studies have concluded on probiotic activity in marine animals upon ingestion. Limitations in culture harvesting and shelf life extension have indeed constrained commercial viability. There are, however, scattered pieces of evidence that microalgae play prebiotic roles, owing to their richness in oligosaccharides-hardly fermented by other members of the intestinal microbiota, or digested throughout the gastrointestinal tract of humans/animals for that matter. However, consistent applications exist only in the dairy industry and aquaculture. Despite the underlying potential in formulation of functional food/feed, extensive research and development efforts are still required before microalgae at large become a commercial reality in food and feed formulation.

Plant cell culture technology in the cosmetics and food industries: current state and future trends.

The production of drugs, cosmetics, and food which are derived from plant cell and tissue cultures has a long tradition. The emerging trend of manufacturing cosmetics and food products in a natural and sustainable manner has brought a new wave in plant cell culture technology over the past 10 years. More than 50 products based on extracts from plant cell cultures have made their way into the cosmetics industry during this time, whereby the majority is produced with plant cell suspension cultures. In addition, the first plant cell culture-based food supplement ingredients, such as Echigena Plus and Teoside 10, are now produced at production scale. In this mini review, we discuss the reasons for and the characteristics as well as the challenges of plant cell culture-based productions for the cosmetics and food industries. It focuses on the current state of the art in this field. In addition, two examples of the latest developments in plant cell culture-based food production are presented, that is, superfood which boosts health and food that can be produced in the lab or at home.

The research and implementation continuum of biofortified sweet potato and maize in Africa.

The enhancement of sweet potato and maize with provitamin A carotenoids has been part of HarvestPlus's research continuum since the formation of the biofortification project. This review includes case studies of biofortification strategies used for sweet potato in Uganda and orange maize in Zambia. The current status of the science and release of biofortified varieties was reviewed by three scientists who were part of the HarvestPlus program for more than a decade with input from a scientist who experienced orange maize dissemination in Zambia. High ß-carotene varieties of sweet potato were introduced into South Africa and Mozambique, and efficacy and effectiveness studies, respectively, showed promise to improve vitamin A status, followed by dissemination efforts in Uganda. A randomized, controlled effectiveness trial tested extension models to promote sweet potato and assessed vitamin A intake among Ugandans. Orange maize breeding was initially a challenge, but considering that the carotenoid biosynthetic pathway was present in maize germplasm, breeders quickly bred higher amounts of provitamin A into the maize that was ultimately released in Zambia. Initial resistance occurred because orange maize was associated with yellow maize, which had negative connotations associated with food aid and animal feed, and consumers preferred white maize. Currently, both orange crops are available on the market.

Technological properties of amazonian oils and fats and their applications in the food industry.

The application of lipids to food production is dependent on their physical, chemical, and nutritional properties. In this study, pracaxi oil, passion fruit oil, cupuassu fat, and palm stearin underwent physicochemical analyses and were combined at ratios of 40:60, 50:50, 60:40, and 70:30 to assess their potential applications in the food industry. Pracaxi oil, passion fruit oil, and cupuassu fat had interesting fatty acid profiles from a nutritional standpoint, displaying the lowest atherogenicity and thrombogenicity indices (0.02 and 0.14; 0.12 and 0.34; 0.16 and 0.65), respectively. Palm stearin had high thermal stability (7.23h). The primary applications of the blends obtained in this study are in table and functional margarine, particularly the pracaxi-stearin and passion fruit-stearin 40:60 and 50:50, pracaxi-cupuassu 60:40 and 70:30, and passion fruit-cupuassu 40:60 blends. The results suggest new industrial applications, especially for pracaxi and passion fruit oils, which are commonly applied in the cosmetic industry.

Present Global Situation of Amino Acids in Industry.

At present, amino acids are widely produced and utilized industrially. Initially, monosodium glutamate (MSG) was produced by extraction from a gluten hydrolysate. The amino acid industry started using the residual of the lysate. The discovery of the functions of amino acids has led to the expansion of their field of use. In addition to seasoning and other food use, amino acids are used in many fields such as animal nutrients, pharmaceuticals, and cosmetics. On the other hand, the invention of the glutamate fermentation process, followed by the development of fermentation methods for many other amino acids, is no less important. The supply of these amino acids at a low price is very essential for their industrial use. Most amino acids are now produced by fermentation. The consumption of many amino acids such as MSG or feed-use amino acids is still rapidly increasing.

Composition and Nutrient Information of Non-Alcoholic Beverages in the Spanish Market: An Update.

The aim of this study was to draw an updated map of the nutrition facts in the different categories of non-alcoholic beverages in the Spanish market based on the information declared on the labels of these products; we expect this first step to justify the need for the coordination and harmonization of food composition tables in Spain so that there will be an updated database available to produce realistic scientific nutrient intake estimates in accordance with the actual market scenario. MATERIALS AND METHODS: The nutrition facts declared on the labels of non-alcoholic beverages by manufacturers in Spain were compiled and studied. RESULTS: The database included 211 beverages classified in 7 groups with energy/carbohydrate content per 100 mL ranging from 0-55 kcal/0-13 g for soft drinks; 2-60 kcal/0-14.5 g for energy drinks; 24-31 kcal/5.8-7.5 g for sports drinks; 1-32 kcal/0-7.3 g for drinks containing mineral salts in their composition; 14-69 kcal/2.6-17 g for fruit juice, nectar, and grape musts; 43-78 kcal/6.1-14.4 g for vegetable drinks; and 33-88 kcal/3.6-14 g for dairy drinks. CONCLUSION: The current non-alcoholic beverage market is a dynamic, growing, and highly innovative one, allowing consumers to choose according to their preferences, needs, or level of physical activity at any moment of the day.

The Interrelationships between Lactose Intolerance and the Modern Dairy Industry: Global Perspectives in Evolutional and Historical Backgrounds.

Humans learned to exploit ruminants as a source of milk about 10,000 years ago. Since then, the use of domesticated ruminants as a source of milk and dairy products has expanded until today when the dairy industry has become one of the largest sectors in the modern food industry, including the spread at the present time to countries such as China and Japan. This review analyzes the reasons for this expansion and flourishing. As reviewed in detail, milk has numerous nutritional advantages, most important being almost an irreplaceable source of dietary calcium, hence justifying the effort required to increase its consumption. On the other hand, widespread lactose intolerance among the adult population is a considerable drawback to dairy-based foods consumption. Over the centuries, three factors allowed humans to overcome limitations imposed by lactose intolerance: (i) mutations, which occurred in particular populations, most notably in the north European Celtic societies and African nomads, in which carriers of the lactose intolerance gene converted from being lactose intolerant to lactose tolerant; (ii) the ability to develop low-lactose products such as cheese and yogurt; and (iii) colon microbiome adaptation, which allow lactose intolerant individuals to overcome its intolerance. However, in a few examples in the last decade, modern dairy products, such as the popular and widespread bio-cultured yogurts, were suspected to be unsuitable for lactose intolerant peoples. In addition, the use of lactose and milk-derived products containing lactose in non-dairy products has become widespread. For these reasons, it is concluded that it might be important and helpful to label food that may contain lactose because such information will allow lactose intolerant groups to control lactose intake within the physiological limitations of ~12 g per a single meal.

Probióticos: del laboratorio al consumidor / Probiotics: from the lab to the consumer

Introducción: En los últimos años, el campo de los probióticos ha experimentado un gran auge. Sin embargo, de los miles de cepas aisladas cada año por su potencial probiótico en los laboratorios de todo el mundo, muy pocas pasan a una fase de desarrollo industrial y menos aún son las que consiguen una vida comercial. Objetivo: En este artículo, se revisan los principales aspectos que se deben tener en cuenta en el, habitualmente, largo y tortuoso camino que debe seguir una cepa desde su aislamiento inicial hasta su comercialización. Resultados y conclusiones: Cualquier microorganismo probiótico debe estar correctamente identificado a nivel de especie y cepa. La secuencia del genoma es la mejor identificación posible, además de proporcionar información muy valiosa sobre su seguridad, funcionalidad y propiedades de interés tecnológico. Los casos en los que se ha podido establecer una relación entre un probiótico y un efecto adverso son muy escasos y han afectado a personas con patologías subyacentes. Globalmente, aunque las distintas pruebas in vitro, ex vivo y en modelos animales proporcionan información útil durante el proceso de selección de cepas, los únicos datos que permiten evaluar la seguridad y eficacia de un probiótico de una forma directa son los que se obtienen en el curso de ensayos clínicos correctamente diseñados y dirigidos específicamente a la población diana. Por otra parte, las empresas que comercializan probióticos tienen la necesidad de obtener una biomasa muy elevada de forma económicamente rentable y de que la concentración de bacterias viables necesaria para ejercer el efecto beneficioso se mantenga hasta el final de la vida útil del producto. Finalmente, los aspectos comerciales son determinantes en la decisión de afrontar el desarrollo industrial y la puesta en el mercado de un probiótico (AU)

Introduction: In the last years, the field of probiotics has grown notably. However, out of the thousands of strains isolated each year in the labs around the world, very few enter in a phase of industrial development and even a lower number go to the market. Objective: In this article, the main aspects that have to be taken into account in the, usually, long and winding road that a strain must follow from isolation to the market are reviewed Results and conclusions: A probiotic microorganism has to be correctly identified at the species and strain levels. The genome sequence is the gold identification standard and provides valuable information on the safety, functionality and technological properties of a strain. The cases in which a link between a probiotic and an adverse effect has been established are scarce and have involved people with underlying pathologies. There is a wide variety of in vitro, ex vivo and animal model assays for the screening of probiotics, which provide useful information throughout the selection process; however, correctly designed clinical trials are the only way to obtain direct results on the safety and efficacy of a probiotic to the target population. Probiotic companies have the need to obtain a very high bacterial biomass in an economically viable manner while preserving the concentration of live bacteria required for exerting the expected beneficial effect until the end of the probiotic’s shelf life. Finally, commercial aspects play a key role in the decision of starting an industrial development and, eventually, to place a probiotic in the market (AU)

Considerations for rice fortification in public health: conclusions of a technical consultation.

Fortification of staple foods and commonly used condiments with vitamins and minerals has been considered one of the most cost-effective interventions to prevent and control micronutrient deficiencies. Because of its wide local consumption, acceptability, reach, and quantum of consumption, rice (Oryza sativa) far exceeds the requirements of a staple food vehicle that can be considered for fortification purposes at a population-level intervention. The World Health Organization (WHO) has the mandate to develop evidence-informed guidelines for the fortification of staple foods as a public health intervention, including rice fortification with micronutrients. The WHO, in collaboration with the Global Alliance for Improved Nutrition (GAIN), convened a consultation on "Technical Considerations for Rice Fortification in Public Health" in Geneva, Switzerland on October 9-10, 2012 to provide technical inputs to the guideline development process, particularly with reference to feasibility and implementability. The industrial and regulatory technical considerations in rice fortification, as well as the considerations for implementing it as a public health strategy and assuring equitable access and universal coverage, were reviewed in this consultation. This paper summarizes the discussions and priority research areas for the forthcoming years.

Food-pharma convergence in medical nutrition- best of both worlds?

At present, industries within the health and life science sector are moving towards one another resulting in new industries such as the medical nutrition industry. Medical nutrition products are specific nutritional compositions for intervention in disease progression and symptom alleviation. Industry convergence, described as the blurring of boundaries between industries, plays a crucial role in the shaping of new markets and industries. Assuming that the medical nutrition industry has emerged from the convergence between the food and pharma industries, it is crucial to research how and which distinct industry domains have contributed to establish this relatively new industry. The first two stages of industry convergence (knowledge diffusion and consolidation) are measured by means of patent analysis. First, the extent of knowledge diffusion within the medical nutrition industry is graphed in a patent citation interrelations network. Subsequently the consolidation based on technological convergence is determined by means of patent co-classification. Furthermore, the medical nutrition core domain and technology interrelations are measured by means of a cross impact analysis. This study proves that the medical nutrition industry is a result of food and pharma convergence. It is therefore crucial for medical nutrition companies to effectively monitor technological developments within as well as across industry boundaries. This study further reveals that although the medical nutrition industry's core technology domain is food, technological development is mainly driven by pharmaceutical/pharmacological technologies Additionally, the results indicate that the industry has surpassed the knowledge diffusion stage of convergence, and is currently in the consolidation phase of industry convergence. Nevertheless, while the medical nutrition can be classified as an industry in an advanced phase of convergence, one cannot predict that the pharma and food industry segments will completely converge or whether the medical industry will become an individual successful industry.

Agricultural biodiversity as a link between traditional food systems and contemporary development, social integrity and ecological health.

Traditional food systems offer a key link between the social and economic resilience of smallholder farmers and pastoralists and the sustainable food and nutrition security of global populations. This paper addresses issues related to socio-cultural diversity and the continuing complex engagement of traditional and modern communities with the plants and animals that sustain them. In light of some of the unhealthful consequences of the 'nutrition transition' to globalized modern diets, the authors define and propose a process for a more successful food system transition that balances agro-biodiversity and processed commodities to support diet diversity, health and social equity alongside sustainable economic growth. We review empirical research in support of practice and policy changes in agriculture, economic development and health domains as well as cross-sectoral and community-based innovation. High-value food crops within domestic and global value chains can be an entry point for smallholders' participation as contributors and beneficiaries of development, while sustainable small farms, as purveyors of environmental and public health services, diversify global options for long-term adaptation in the face of environmental uncertainty.

Trends in trans fatty acids reformulations of US supermarket and brand-name foods from 2007 through 2011.

INTRODUCTION: Although some US food manufacturers have reduced trans fatty acids (TFA) in their products, it is unknown how much TFA is being reduced, whether pace of reformulation has changed over time, or whether reformulations vary by food type or manufacturer. METHODS: In 2007, we identified 360 brand-name products in major US supermarkets that contained 0.5 g TFA or more per serving. In 2008, 2010, and 2011, product labels were re-examined to determine TFA content; ingredients lists were also examined in 2011 for partially hydrogenated vegetable oils (PHVO). We assessed changes in TFA content among the 270 products sold in all years between 2007 and 2011 and conducted sensitivity analyses on the 90 products discontinued after 2007. RESULTS: By 2011, 178 (66%) of the 270 products had reduced TFA content. Most reformulated products (146 of 178, 82%) reduced TFA to less than 0.5 g per serving, although half of these 146 still contained PHVO. Among all 270 products, mean TFA content decreased 49% between 2007 and 2011, from 1.9 to 0.9 g per serving. Yet, mean TFA reduction slowed over time, from 30.3% (2007-2008) to 12.1% (2008-2010) to 3.4% (2010-2011) (P value for trend < .001). This slowing pace was due to both fewer reformulations among TFA-containing products at start of each period and smaller TFA reductions among reformulated products. Reformulations also varied substantially by both food category and manufacturer, with some eliminating or nearly eliminating TFA and others showing no significant changes. Sensitivity analyses were similar to main findings. CONCLUSIONS: Some US products and food manufacturers have made progress in reducing TFA, but substantial variation exists by food type and by parent company, and overall progress has significantly slowed over time. Because TFA consumption is harmful even at low levels, our results emphasize the need for continued efforts toward reformulating or discontinuing foods to eliminate PHVO.
