ABSTRACT

Immunity is the major mechanism of host defence system against infectious and chronic diseases. The recent global concern of recent viral infection of SARS-CoV-19 has raised the demand of functional foods, nutraceuticals and fruits that can boost immunity. This will help in managing the overall physiological health and prevention of infectious and chronic diseases. Medicinal plants and fruits can help in boosting immunity through modulation of immune system and changing the types of immune response such as involvement of the induction, expression or amplification of the genes and proteins in inflammation and antioxidant system. The traditional medicine systems have used a wide variety of plants and fruits as supplement for immunomodulation including those for stimulation of immune system as well as immune compromisation deemed per se. Some of the plants that have been listed for immune boosting abilities included Curcuma longa, Withania somnifera, Phyllanthus emblica, Azadirachta indica, Panax ginseng, Rhododendron spiciferum, Caesalpinia bonducella, Tinospora cordifolia, Capparis zeylanica, Asparagus racemosus, Nelumbo nucifera, Arnica montana, Calendula officinalis, Echinacea purpurea and Euphorbia tirucalli. Reports indicate that a wide variety of phytochemicals like polysaccharide, alkaloids, flavonoids, terpenoids, lactones and glycoside have shown immunomodulatory properties under different pathophysiological conditions. Amongst the diverse chemical profile of plant extracts, polysaccharides are the water-soluble molecules that could activate immune responses when interacting directly with immune cells, while hydrophobic compounds like flavonoids such as quercetin and luteolin and terpenoids such as sesquiterpene lactones and curcumin showed potent immunomodulatory effects. Growing evidences suggest that phytochemicals from functional foods and fruits may be useful in maintaining the cytokine and chemokine balance, regulating oxidative status of cells, and targeting the specific cellular receptors as therapeutic targets. This chapter comprehensively enlists the plant resources with immune boosting abilities and explore their phytochemical characterization and molecular mechanism behind their protective effects. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

ABSTRACT

The aim of this study was to evaluate the effect of the freeze-drying process on the preservation of mare's milk. This was achieved through the characterization of the functional properties of reconstituted freeze-dried mare's milk. The chemical composition, bulk density, foam capacity, and ability to form emulsions of the atherogenic, thrombogenic, and hypercholesterolemic fatty acid index were investigated. The freeze-drying process did not change the proportion of the milk components in the dry matter. The moisture content of the freeze-dried mare's milk was 10.3 g/kg and the bulk was below 0.1 g/mL. The foaming capacity was 111.3%; hence, the foaming capacity of the milk was very poor. The oil binding capacity was 2.19 g/g of protein. The freeze-drying process improves the binding degree and retention of oil by milk proteins, but produced foam was unstable, short-lived, and lacked the ability to retain air fractions. The atherogenic index and thrombogenic index values calculated for reconstituted milk were 1.02 and 0.53, respectively. The hypercholesterolemia fatty acid index was 25.01.

ABSTRACT

This review is aimed to explore the health beneficial effects of probiotics which are live microorganisms that provide a positive health influence on humans when taken in sufficient quantity. Lactic acid bacteria, bifidobacteria, and yeast are frequently used as probiotics. These health-beneficial bacteria could compete with pathogens and modulate the gut microbiota, and exhibit immunomodulatory, anti-obesity, anti-diabetic, and anti-cancer activities which are discussed in this review. Moreover, recent studies showed that probiotics could neutralize COVID-19 infections. Hence, probiotics have become an alternative to several drugs including antibiotics. In addition, probiotic efficacy also depends on the delivery system as the delivery agents help the bacteria to survive in the harsh environment of the human gut. Considering these health benefits of probiotics, now it has been applied to different food materials which are designated as functional food. This review explored a portrait of the beneficial effects of probiotics on human health.Copyright © 2022 The Author(s)

ABSTRACT

COVID-19 is a significant threat to humanity in the present day due to the rapid increase in the number of infections worldwide. While most children may be spared of the direct mortality effects of the disease, those with weak immune systems are prone to adverse effects. Child mortality increases due to the stress caused to the health care system that disrupts essential health care needs such as immunisation and antenatal care. The use of functional foods (FF) aids in disease-prevention as they are known to have protective effects against COVID-19 by boosting children's cellular and humoral immunity. Plant components such as glycyrrhizin, epigallocatechin gallate, allicin, and fucoidan exhibit antiviral properties against various viruses, including SARS-CoV 2. Microbial foods that are made of probiotics, can enhance immunity against various respiratory viruses. Food enriched with additives such as lactoferrin, piperine, and zinc can boost immunity against COVID-19. With proper definitive drug therapy not available for treating COVID-19 and most of the disease management tools rely on symptoms and non-specific supportive care, developing a functional paediatric formulation will prevent further deterioration in infant health. It is wise to investigate the toxicological aspects of Functional Foods components especially when formulating for children. The safe limits of ingredients should be strictly followed during FFs formulation. Stronger regulations with advanced analytical techniques can help to formulate functional foods into the mainstream in child nutraceuticals. The purpose of this review is to compile collective information on the functional nutraceuticals specifically for infants and children up to the age of 10 years that could confer immunity against COVID-19 and other related viruses.

ABSTRACT

Since the global shock caused by COVID-19, interest in immune-enhancing materials is rapidly increasing, therefore, the development of novel materials is necessary from the industrial and health perspectives. In this study, we selected Nelumbo nucifera Gaertner Seed Extract (NSE) and evaluated immune enhancement effect by using RAW 264.7 murine macrophage cells. NSE significantly up-regulated production of nitric oxide and reactive oxygen species without affecting cell viability in RAW 264.7 cells. Additionally, NSE exhibited an increase of inducible nitric oxide synthase and cyclooxygenase-2 expression in RAW 264.7 cells. The enzyme-linked immuno-sorbent assay results showed that NSE-treatment significantly enhanced production of interleukin 6 and tumor necrosis factor-α in RAW 264.7 cells. Furthermore, we observed that NSE significantly up-regulated phosphorylation of p65, I kappa B kinase α/β, and I kappa B (IκB) α as well as down-regulation of IκB α expression in RAW 264.7 cells. Our findings indicate that NSE could be the potential health-functional food material with capacity of improving immunity via Nuclear factor-kappa B signaling pathway. © 2023, Korean Society for Applied Biological Chemistry.

ABSTRACT

This review focused on compiling, summarizing, updating the information available on the colostrum and its health benefits. Colostrum is the first milk secreted by the mammary gland of female mammals immediately after birth during the first few days, and its composition differs from the mature milk. It ensures immune support for newborns in the early stages of life. It is a divine immune gift from the Creator. Mammalian colostrum contains unique components rich in nutritional macronutrients (proteins, fat, carbohydrates) and micronutrients (vitamins, minerals, antioxidants) and many bioactive substances like antimicrobial factors (Igs, LF, LP, LZ, cytokines) and growth factors (EGF, TGFalpha and beta, IGF-1 and 2, FGF, PDGF, GH), which are necessary to stimulate the immune systems that newborns need for health and survival life. Physicochemical composition changes dramatically in the first few days that distinguish it from mature milk. This reverses an essential difference in their biological function as fractional sources or for health-promotion. So it is considered one of the best natural food supplements consumed within various life stages. Colostrum is used to treat cancer, AIDS, polio, heart disease, and rheumatoid arthritis. Hyper-immune colostrum or milk collected from cows immunized by SARS-CoV-2, it can grant protection short-term from infection in humans and can be used as an alternative way to produce specific antibodies against CoVID-19 until effective excess vaccines against new mutations can be available. Likewise, colostrum and its components contribute as a non-drug alternative to the clinical management of CoVID-19. Also, lactoferrin and its supplements are effective in preventing and treating people with coronavirus infection. Therefore, due to these previous multiple functions, colostrum is considered as a natural food, called miracle immune milk, and used as a medicine.Copyright © 2022 The Author

ABSTRACT

3D printing technology (3DP) as additive manufacturing is an innovative design technology that can meet the individual nutritional and sensory needs of consumers. Therefore, the aim of this work was to apply 3DP in the production of a strawberry-based functional product with the addition of two hydrocolloids (corn and wheat starch) in three proportions (10, 15 and 20%) and to investigate the influence of 3DP process parameters on physico-chemical and textural properties, as well as the bioactive and antioxidant potential and microbiological stability, with(out) the addition of natural antimicrobial agents. Starch type had a significant effect on all tested bioactive compounds, as well as on starch content, except for total phenolic and hydroxycinnamic acid contents. Considering the content of bioactive compounds and antioxidant capacity, program 2 proved to be more suitable than program 1. All samples exhibited good textural properties, a high degree of stability and minimal geometric deviations. Regarding microbiological safety, no pathogenic bacteria were found in the 3DP samples during storage. The 3DP sample with added citral at a concentration of 75 mg L-1 showed the best microbiological quality. Ultimately, 3DP can be successfully used for the production of new strawberry-based functional products.

ABSTRACT

Molecular docking and molecular dynamics aided virtual search of OliveNet™ directory identified potential secoiridoids that combat SARS-CoV-2 entry, replication, and associated hyperinflammatory responses. OliveNet™ is an active directory of phytochemicals obtained from different parts of the olive tree, Olea europaea (Oleaceae). Olive oil, olive fruits containing phenolics, known for their health benefits, are indispensable in the Mediterranean and Arabian diets. Secoiridoids is the largest group of olive phenols and is exclusive to the olive fruits. Functional food like olive fruits could help prevent and alleviate viral disease at an affordable cost. A systematized virtual search of 932 conformers of 78 secoiridoids utilizing Autodock Vina, followed by precision docking using Idock and Smina indicated that Nüzhenide oleoside (NZO), Oleuropein dimer (OED), and Dihydro oleuropein (DHO) blocked the SARSCoV-2 spike (S) protein-ACE-2 interface;Demethyloleuropein (DMO), Neo-nüzhenide (NNZ), and Nüzhenide (NZE) blocked the SARS-CoV-2 main protease (Mpro). Molecular dynamics (MD) simulation of the NZO-S-protein-ACE-2 complex by Desmond revealed stability during 50 ns. RMSD of the NZO-S-protein-ACE-2 complex converged at 2.1 Å after 20 ns. During MD, the interaction fractions confirmed multiple interactions of NZO with Lys417, a crucial residue for inhibition of S protein. MD of DMO-Mpro complex proved its stability as the RMSD converged at 1.6 Å. Analysis of interactions during MD confirmed the interaction of Cys145 of Mpro with DMO and, thus, its inhibition. The docking predicted IC50 of NZO and DMO was 11.58 and 6.44 μM, respectively. Molecular docking and dynamics of inhibition of the S protein and Mpro by NZO and DMO correlated well. Docking of the six-hit secoiridoids to IL1R, IL6R, and TNFR1, the receptors of inflammatory cytokines IL1β, IL6, and TNFα, revealed the anti-inflammatory potential except for DHO. Due to intricate structures, the secoiridoids violated Lipinski's rule of five. However, the drug scores of secoiridoids supported their use as drugs. The ADMET predictions implied that the secoiridoids are non-toxic and pose low oral absorption. Secoiridoids need further optimization and are a suitable lead for the discovery of anti-SARS-CoV-2 therapeutics. For the moment, olive secoiridoids presents an accessible mode of prevention and therapy of SARS-CoV-2 infection.

ABSTRACT

Banana is one of the major crop in India producing large quantities of pseudo-stem as bio-waste after harvesting and becomes the adverse environmental concern due to the disposal either at the outside of the fields or incineration. This particular scenario demanded for recycling or conversion of the huge biomass generated as waste into utilizable products to reduce the consequences of environmental adverse effects. The current investigation focused on the utilization of pseudostem byproduct by converting into value added healthy functional food product in the form of banana center core coconut cookies. The product was standardized by formulating three different experimental trials by substituting a part of wheat flour with three variations viz., 5, 10 and 15 per cent levels respectively. The acceptable levels were compared organoleptically against reference sample without addition of banana center core flour. The findings demonstrated high overall mean acceptable scores of above nine in the reference (9.25), first (9.16) and second (9.02) experimental trials. The third experimental trial with the incorporation of fifteen per cent showed low overall mean organoleptic score (7.36). Pseudo-stem being potential source of dietary fiber, protein and micro-minerals, the second experimental trial was considered as the standardized formula. The nutrient composition analyzed identified that the standardized cookies were nutritionally rich as evidenced by the estimated essential nutrients viz., protein(5.41g), fat(10.53g), dietary fiber(7.28g), ash(0.21mg), calcium(48.36mg) and iron(2.12). The observations well demonstrated the beneficial utility of bio-waste in food products especially in baking denoting the challenging task to explore and development of wide range of pseudo-stem based value added healthy functional food products. The antioxidant and immuno-protective properties associated with pseudo-stem especially beneficial during the COVID-19 pandemic conditions to fight against immune-suppressive corona virus.

ABSTRACT

Background: Food additives act as preventive measures and promote a healthy immune response against pathogenic diseases. There are several functional food additives with antiviral potential that are part of our daily food supplements, which can be exploited to improve the immunity of the human being during the pandemic of COVID-19. Scope and Approach: For this study, an extensive database search using the scientific databases and Google Scholar, as well as commercial search engines, such as Google and Google Patent, was con-ducted to explore commercial and patentable applications. Key Finding: Food additives, such as Phyllanthus emblica, Long pepper, Cinnamon, Turmeric, Cardamom, Ginger, Garlic, Holy Basil, and Liquorice, are used in traditional cultures as preventive treatments. The phytocompounds extracted from these food additives are immune modulators against various pathogenic inflammations. Enhancing the immune response and boosting health are the benefits of these food additives. Conclusion(s): The research literature and reputable sources online confirm that functional food additives in a regular diet may help cure COVID-19 disease. It is necessary to conduct scientific research to determine the effectiveness of food additives. Future Direction: The majority of diseases are caused by metabolic disorders. It is clear that diet plays a major role in controlling the inflammation associated with diseases and metabolic disorders. There is still a lack of phytochemical screening of compounds in food additives and their interaction with me-tabolism. This effort will help the science community to think outside of the box of medicine. Copyright © 2022 Bentham Science Publishers.

ABSTRACT

The fast food dietary life style habits had rapidly put the people in the midst of risky conditions especially showed adverse impacts on snacks. Most of the Indian traditional foods typically contains highly nutritious indigenous foods and bringing slight variation in ingredients formulations proved to be more functional. Navadhanya in the Indian culture occupies auspicious place and provide numerous nutritional and therapeutic benefits. In fact, the current pandemic COVID-19 pandemic scenario requires healthy snacking behaviour. Based on this background, the common traditional foods viz., boondhi laddu, mysorepak, kajjikayalu and muruku were purposefully chosen to develop functional foods with the incorporation of navadhanya mix at 50 per cent level. The acceptability studies carried out organoleptically both at the baseline and after storage period of one week had clearly demonstrated highly acceptable mean organoleptic scores and not significant difference statistically. The findings well explained the retention of freshness even at one-week storage period. On the other hand, the nutrient analysis carried out had shown sufficient evidence that the functional foods prepared were energy dense and rich in essential nutrients such as protein, fat, calcium and iron. Promotion of indigenous healthy foods not only improves healthy but also play crucial role in the attainment of food and nutrition security. Copyright © 2022, Anka Publishers. All rights reserved.

ABSTRACT

Background: In Taiwan, the aerial part of Adenostemma lavenia (Al) is used in the form of herbal tea or in a folk remedy primarily to mitigate inflammatory conditions in the lungs and liver. Due to the excellent health benefits of Al against inflammation, it has become increasingly crucial and in great demand during the COVID-19 pandemic. However, Al has been found to be adulterated with Wedelia biflora, Sigesbeckia orientalis, and/or Wedelia chinensis because of similarities in appearance and vernacular names. Methods: This study aimed to develop a PCR-RFLP DNA molecular method for the authentication of Al. The restriction enzyme BsrI was used according to the sequencing and alignment results of PCR products in the ITS2 regions of Al and its adulterants. Gel electrophoresis resulted in the clear separation of Al and its adulterants into two distinct categories. Results: In conclusion, the PCR-RFLP authentication method developed herein provides an easy, rapid, and accurate method to distinguish Al from its adulterants to assure user health and safety.

ABSTRACT

Metabolomics, as a new omics technology, has been widely accepted by researchers and has shown great potential in the field of nutrition and health in recent years. This review briefly introduces the process of metabolomics analysis, including sample preparation and extraction, derivatization, separation and detection, and data processing. This paper focuses on the application of metabolomics in food-derived bioactive ingredients. For example, metabolomics techniques are used to analyze metabolites in food to find bioactive substances or new metabolites in food materials. Moreover, bioactive substances have been tested in vitro and in vivo, as well as in humans, to investigate the changes of metabolites and the underlying metabolic pathways, among which metabolomics is used to find potential biomarkers and targets. Metabolomics provides a new approach for the prevention and regulation of chronic diseases and the study of the underlying mechanisms. It also provides strong support for the development of functional food or drugs. Although metabolomics has some limitations such as low sensitivity, poor repeatability, and limited detection range, it is developing rapidly in general, and also in the field of nutrition and health. At the end of this paper, we put forward our own insights on the development prospects of metabolomics in the application of bioactive ingredients in food.

ABSTRACT

This study was conducted to investigate the influence of pumpkin cultivar as a fermented semi-product on the selected quality parameters of functional non-dairy frozen desserts, which were prepared using the potentially probiotic strain cultures L. rhamnosus Lock 0900 and L. casei O14. Microbiological status, pH, sugar and carotenoids content, antioxidant activity, color and sensory quality have been checked. Regardless of the pumpkin cultivar used, the lactic acid fermentation of pulps with selected bacterial strains decreased reducing sugar and total sugars content. Improvement in the antioxidant activity was also observed. The impact of the individual sensory attributes on the overall quality was determined. The overall quality of the investigated pumpkin sorbets was positively driven by the sweet taste, pumpkin flavor, smoothness of texture, and negatively driven by acidic flavor, pungent taste, and bitter taste, verified by PCA method. All of the final products achieved high survival of probiotics (higher than 8.4 log CFU/g) and revealed a good sensory quality (overall quality higher than 8 c.u). The treatments with the cultivar “Melon Yellow” of the Cucurbita maxima species, were characterized by significantly higher (p < 0.05) carotenoids content, total sugars and reducing sugars content and antioxidant activity, measured by two methods. It can be concluded that the pumpkin cultivar and strain culture used for the fermentation affect the count of potentially probiotic bacteria in the final products, the composition of bioactive compounds, antioxidant activity and sensory quality of the functional pumpkin frozen desserts.

ABSTRACT

Diabetes is the tenth most common comorbidity in coronavirus disease, hence COVID-19 patients with this disease showed higher mortality rates and worse outcomes. Therefore, Management of diabetes during the pandemic became more critical, especially in ensuring patients consume functional foods containing diets, such as sweet potato, cassava, and taro, among the top ten abundant-traditional tubers in Indonesia. These foods are rich in protein, vitamin C, thiamine, riboflavin, niacin, and dietary fibre. Carbohydrate-rich foods, which constitute around 60% of the average diet should be considered. This study evaluated the potential of the three most consumed Indonesian tubers;sweet potato, cassava, and taro, as functional foods for managing diabetes during the pandemic. These foods were selected based on their chemical composition, antioxidant activity, and in silico molecular docking against COVID-19 and diabetes-related target proteins. The target proteins are ACE2 (angiotensin-converting enzyme 2), TMPRSS-2 (transmembrane serine protease 2), DPP IV (dipeptidyl peptidase IV), and α-glucosidase. The results showed that sweet potato has the highest phenolic compounds content and antioxidant activity, valued at 7.40 ± 0.20 mg/g GAE and 9.39 ± 0.3%, respectively. Moreover, molecular docking results indicated that sweet potato phenolic compounds, namely isorhamnetin, peonidin, and catechin against DPP IV, isorhamnetin, peonidin, and quercetin against ACE2, isorhamnetin and quercetin against α-glucosidase, and epicatechin against TMPRSS2 strongly interacted with the target proteins. In conclusion, cassava, taro, and sweet potato were the most potential functional foods for diabetes management during the pandemic.
