However, achieving selective molecular differentiation and eventually enhancing peptide bioactivities require costly cascades of membranes.

Multifunctional dietary approach reduces intestinal inflammation in relation with changes in gut microbiota composition in subjects at cardiometabolic risk: the SINFONI project.

The development of cardiometabolic (CM) diseases is associated with chronic low-grade inflammation, partly linked to alterations of the gut microbiota (GM) and reduced intestinal integrity. The SINFONI project investigates a multifunctional (MF) nutritional strategy's impact combining different bioactive compounds on inflammation, GM modulation and CM profile. In this randomized crossover-controlled study, 30 subjects at CM-risk consumed MF cereal-products, enriched with polyphenols, fibers, slowly-digestible starch, omega-3 fatty acids or Control cereal-products (without bioactive compounds) for 2 months.

Upcycling calf cruor slaughterhouse by-product by peptic hydrolysis and identification of three novel antifungal peptides following a regression based-machine learning approach.

Calf cruor (C-cru) is an understudied source of antimicrobial peptides that can be used for meat product biopreservation under a circular economy framework. This study assessed the impact of pH and peptic hydrolysis duration of C-cru on the enzymatic mechanism, peptide population, and antimicrobial activities (antibacterial, antifungal, and anti-yeast). The results showed that peptic hydrolysis of C-cru has similar enzymatic mechanisms to adult bovine hemoglobin, fostering the development of a zipper mechanism at pH 2 and 3, while the one-by-one mechanism is promoted at pH 4 and 5.

Supplementation with a cranberry extract favors the establishment of butyrogenic guilds in the human fermentation SHIME system.

Proanthocyanidins (PAC) and oligosaccharides from cranberry exhibit multiple bioactive health properties and persist intact in the colon post-ingestion. They display a complex bidirectional interaction with the microbiome, which varies based on both time and specific regions of the gut; the nature of this interaction remains inadequately understood. Therefore, we aimed to investigate the impact of cranberry extract on gut microbiota ecology and function.

Their growth kinetics and impacts on total phenols, total anthocyanins, total proanthocyanins, total organic acids, pH, titratable acidity, and volatile compounds were assessed.

Techno-functional properties and structural characteristics of cricket protein concentrates affected by pre-treatments and ultrafiltration/diafiltration processes.

This study aimed to evaluate different pre-treatments on cricket flour (CF), solvent-defatting (CFH), and supercritical-defatting (CFS) to obtain cricket protein concentrate (CPC) by ultrafiltration (UF)-diafiltration (DF) and evaluate the UF-DF performance, techno-functional properties, and digestibility. Results showed that defatting efficiency was 63 % and 85 % for solvent-defatting and supercritical fluid defatting, respectively. The supercritical fluid extraction process decreased the protein solubility and affected the UF performance, decreasing protein retention by 33 %.
