Exploring the dipeptidyl peptidase-IV inhibitory potential of probiotic-fermented milk: An in vitro and in silico comprehensive investigation into peptides from milk of different farm animals.

Bioactive peptides produced via enzymatic hydrolysis have been widely investigated for their dipeptidyl peptidase-IV (DPP-IV) inhibitory properties. However, the deficit of studies on fermentation as a means to produce DPP-IV inhibitory peptides prompted us to draw a comparative study on DPP-IV inhibitory peptides generated from cow, camel, goat, and sheep milk using probiotic fermentation. Further, peptide identification, in silico molecular interactions with DPP-IV, and ensemble docking were performed.

Plant-Based Fermented Beverages: Nutritional Composition, Sensory Properties, and Health Benefits.

Plant-based beverages have gained consumers' attention for being the main substitutes for dairy milk, especially for people with lactose intolerance, milk allergies, and a prevalence of hypercholesterolemia. Moreover, there is a growing demand for a more sustainable diet and plant-based lifestyle due to concerns related to animal wellbeing, environmental impacts linked to dairy production, and the rising cost of animal-derived foods. However, there are some factors that restrict plant-based beverage consumption, including their nutritional quality and poor sensory profile.

Beyond Human Nutrition of Edible Insects: Health Benefits and Safety Aspects.

Nowadays, edible insects are considered an outstanding source of nutrients, primarily because they contain high-quality protein, amino acids, and vitamins. Insects are considered a promising alternative protein source towards alleviating future global food shortage problems due to their production considered as being more sustainable by using less agricultural land and water, as well as releasing a smaller amount of greenhouse gas emissions. However, other important aspects to consider about the consumption of edible insects include their health benefits and some safety aspects, which has been relatively overlooked.

Edible insects, a valuable protein source from ancient to modern times.

The current COVID-19 pandemic has demonstrated that we are not prepared to deal with food security amid unexpected situations; the FAO (Food and Agriculture Organization) has stipulated that the future of our food & agriculture looks challenging toward the year 2050; primarily in response to the fact that global population is expected to increase by 9 billion people by 2050. Although entomophagy has been practiced by humans for thousands of years, until recently, edible insects have gained special attention due to their high nutritional value (particularly their high protein and essential amino acid content) and lower environmental impact that could help alleviate the global food demand. Edible insects are classified into eight main orders belonging to Blattodea (cockroaches and termites), Coleoptera (beetles), Diptera (flies), Hemiptera (cicadas, stink bugs), Hymenoptera (bees, wasps, ants), Lepidoptera (butterflies, moths), Odonata (dragonflies), and Orthoptera (crickets, grasshoppers, locusts).

Integration of Molecular Docking Analysis and Molecular Dynamics Simulations for Studying Food Proteins and Bioactive Peptides.

tools, such as molecular docking, are widely applied to study interactions and binding affinity of biological activity of proteins and peptides. However, restricted sampling of both ligand and receptor conformations and use of approximated scoring functions can produce results that do not correlate with actual experimental binding affinities. Molecular dynamics simulations (MDS) can provide valuable information in deciphering functional mechanisms of proteins/peptides and other biomolecules, overcoming the rigid sampling limitations in docking analysis.

Processing insects for use in the food and feed industry.

Although insects are becoming more accepted as potential protein sources for food and feed, the appearance of the insect may be off-putting due to associations of disgust. Edible insects are more likely to be eaten if they are processed into non-recognizable forms. Thus, insects require the use of commercial processing methods that will render the protein suitable for food/feed formulation, while maintaining the safety, nutritional and sensory quality of the final product.

An insight to fermented edible insects: A global perspective and prospective.

The practice of eating insects is not a new phenomenon; however, the interest for their consumption has increased in recent years due to their recognized nutritional value (high content of micro- and macronutrient), potential health benefits (presence of bioactive substances), and low-environmental impact (use of less resources and reduced pollution levels). Currently, research on insects has focused on the promotion of various processing technologies for their use as either ingredients (in a non-recognizable form) to the development of innovative products, or as sources of novel bioactive compounds. In this context, evidence has suggested that alternative technologies, particularly fermentation, could be used the obtain diverse insect-based ingredients/products with unique properties.
