Foods are complicated materials, which contain nutrient substances as well as functional/bioactive compounds, for instance, flavones, pigments, polyphenol, polysaccharides, oligosaccharides, antioxidants, enzymes, and so on. Furthermore, foods will produce more bioactive compounds during digestion. One of the most typical bioactive gastrointestinal products is bioactive peptides. All these functional/bioactive compounds play critical roles in human health and in even some diseases.

Therefore, efficient discovery of such functional/bioactive compounds becomes significant, especially the high-throughput discovery or screening. Because of the rapid development of Information Science and Technology and omics (genomics, proteomics, metabolomics, flavor omics, etc.), high-throughput techniques, and virtual/in silico prediction technology, the efficient discovery and innovation of functional/bioactive compounds in foods can be promoted. Accordingly, this special issue focuses on the new techniques of screening, prediction and design of functional and/or bioactive compounds in foods, including high-throughput methods, virtual/in silico strategies, etc., as well as the novel techniques in the assay of the bioactivities in silico, in vitro or in vivo, even the illustration of molecular mechanism.

Comprehensive lipidomic analysis of the lipids extracted from freshwater fish bones and crustacean shells

The fatty acid composition and lipid molecular species from fish bones and crustacean shells were investigated. The lipids extracted from shrimp and crab shells contained a considerable amount of eicosapentanoic acids and docosahexanoic acids. The total content of PC in shrimp shells was as high as 6.145 mmol/g.

Influenza virus entry and replication inhibited by 8-prenylnaringenin from Citrullus lanatus var. citroides (wild watermelon)

Influenza virus entry and replication inhibited by 8-prenylnaringenin from Citrullus lanatus var. citroides (wild watermelon)

The antiviral activities of 8-prenylnaringenin, which is the ingredient in wild watermelon, were observed against H1N1 and H3N2 influenza subtypes and influenza B viruses, excluding oseltamivir-resistant H1N1 viruses. Since oseltamivir-resistant strains were not inhibited by 8-prenylnaringenin, 8-prenylnaringenin may interact directly with viral neuraminidase.

Zebrafish obesogenic test identifies anti-adipogenic fraction in Moringa oreifera leaf extracts

Zebrafish obesogenic test identifies anti-adipogenic fraction in Moringa oreifera leaf extracts

We performed zebrafish obesogenic test to identify anti-adipogenic fraction in Moringa oleifera leaf. Phenotype-driven zebrafish screening can be a reasonable strategy for identifying bioactive components in natural products. Using zebrafish obesogenic test, we identified that the dichloromethane extract of Moringa oleifera leaf and its subfraction (Fr. 2) reduced VAT accumulation in young zebrafish. In the zebrafish VAT, expression of early adipogenesis markers, cebpb and cebpd, was significantly (p < .05) decreased by Fr. 2, as was the expression of the late differentiation marker cebpa. We also confirmed that the subfractions of Fr. 2 also suppressed adipogenesis in ZOT and mouse 3T3-L1 preadipocytes.

The significance and potential of functional food ingredients for control appetite and food intake

The significance and potential of functional food ingredients for control appetite and food intake

Functional foods can be one of the most influential factors in reducing appetite as long as effective ingredients, such as fiber and protein, are used to design these products. Also, functional foods should be designed to reduce appetite at different levels of oral processing, stomach, small intestine, and large intestine by various mechanisms. Therefore, the satiety power of functional food depends on the type of ingredients and their amount. Because each compound has a different mechanism of action, it is recommended to use different compounds to influence satiety in functional foods.

Evaluation of Nano-curcumin effects against Tartrazine-induced abnormalities in liver and kidney histology and other biochemical parameters

Evaluation of Nano-curcumin effects against Tartrazine-induced abnormalities in liver and kidney histology and other biochemical parameters

Albino male rats were investigated to evaluate the impact of Nano-curcumin (Nano-CUR) administration against Tartrazine (TZ)-induced variations in kidney and liver histology and their related functions. The results support the protective and therapeutic effects of Nano-CUR on the histology of the liver and kidneys and their related functions. Also, Nano-CUR corrects the imbalance in serum glucose (sGlu), alpha-fetoprotein (AFP), protein Kinase-C (PKC), and lipid profiles in TZ-ingested rats compared to control.

Yogurt fortification by microencapsulation of beetroot extract (Beta vulgaris L.) using maltodextrin, gum arabic, and whey protein isolate

Yogurt fortification by microencapsulation of beetroot extract (Beta vulgaris L.) using maltodextrin, gum arabic, and whey protein isolate

Beetroot extract (BE) was encapsulated using maltodextrin (MD), gum arabic (GA), and whey protein isolate (WPI) by implementing a spray-drying method. The highest total phenolic content (TPC) was obtained at 15% MD, 7.5% GA, and 10% WPI. The same results were achieved for antioxidant activity. Increasing the MD and GA contents resulted in a reduction of moisture adsorption of microencapsulated BE powder.

Comparison of the effect of saffron, crocin, and safranal on serum levels of oxidants and antioxidants in diabetic rats: A systematic review and meta-analysis of animal studies

Comparison of the effect of saffron, crocin, and safranal on serum levels of oxidants and antioxidants in diabetic rats: A systematic review and meta-analysis of animal studies

To our knowledge, this is the first systematic review and meta-analysis that has comprehensively investigated the effect of saffron and its active compounds on oxidative stress markers (oxidants and antioxidants). In this meta-analysis, 15 studies were reviewed. The results of our study showed that saffron and its active compounds (crocin and safranal) with high effectiveness led to a reduction in oxidative stress caused by long-term hyperglycemia. In addition, we showed that safranal is more effective than saffron and crocin.

Miao sour soup influences serum lipid via regulation of high-fat diet-induced intestinal flora in obese rats

Miao sour soup influences serum lipid via regulation of high-fat diet-induced intestinal flora in obese rats

Obesity is a health condition of increasing importance. Obesity has been associated with an imbalance in the intestinal flora. Miao sour soup (SS) contains abundant short-chain fatty acids (SCFAs), which can be used as energy substrates to selectively stimulate the growth and reproduction of intestinal flora. This study aims to determine whether SS intervention could restore the imbalanced intestinal flora of rats with high-fat diet-induced obesity. We found improvements in the abundance and diversity of the intestinal flora, and a significant reduction in weight and serum lipid levels following intervention with SS. We believe that our study makes a significant contribution to the literature because our findings demonstrate the therapeutic potential of dietary intake of SS in achieving weight loss and reducing serum lipid levels, thus ameliorating the effects of obesity induced by high-fat diet.

Neuroprotective effects of a novel peptide from Lignosus rhinocerotis against 6-hydroxydopamine-induced apoptosis in PC12 cells by inhibiting NF-κB activation

Neuroprotective effects of a novel peptide from Lignosus rhinocerotis against 6-hydroxydopamine-induced apoptosis in PC12 cells by inhibiting NF-κB activation

In this study, a novel peptide (LRP) was extracted from the fruiting bodies of L. rhinocerotis using gel filtration chromatography. We determined the amino acid sequence of LRP, which was conducive to its artificial synthesis. Moreover, with NF-κB as the target, the neuroprotective function of LRP was explored. LRP may have the potential to act as a neuroprotective agent.

Panax ginseng abuse exhibits a pro-inflammatory effect by activating the NF-κB pathway

Panax ginseng abuse exhibits a pro-inflammatory effect by activating the NF-κB pathway

Excessive consumption of panax ginseng may cause over-activation of the immune system forming "ginseng abuse syndrome". The present results suggested that GFC-F1 purified from ginseng is the crucial component that caused "ginseng abuse syndrome". Moreover, GFC-F1 activates the NF-κB pathway to trigger the immune system leading to inflammatory responses through inducing the phosphorylation of p65 and IκBα.
