Potential Phytopharmacy and Food Applications of Capsicum spp.: A Comprehensive Review
Capsicum genus (Solanaceae) is native to the Americas. Today, it is an important agricultural crop cultivated around the world, not only due to its economic importance, but also for the nutritional value of the fruits. Among their phytochemical constituents, capsaicinoids are characteristic and responsible of the pungency of sharp-tasting cultivars. Moreover, Capsicum and capsaicinoids (mainly, capsaicin) have been largely studied because of their health benefits. Thus, this study reviews the scientific knowledge about Capsicum spp. and their phytochemicals against cancer, diabetes, gastrointestinal diseases, pain, and metabolic syndrome, as well as their antioxidant and antimicrobial acti…
Milk versus caseinophosphopeptides added to fruit beverage: Resistance and release from simulated gastrointestinal digestion
The influence of simulated gastrointestinal digestion on caseinophosphopeptides (CPPs) formation in milk-based fruit beverage was evaluated, together with resistance of a pool of CPPs added to fruit beverage. In milk-based fruit beverage, four CPPs were identified that can be justified by their presence in raw milk or due to processing. When it was subjected to simulated gastrointestinal digestion, 10 CPPs were identified, and only 1 presented the cluster (SpSpSpEE) (3 phosphoseryl group followed by 2 glutamic acid residues), which corresponded to αs2-CN(1-19)4P. CPPs added to fruit beverage are resistant to simulated gastrointestinal digestion, and 16 CPPs were identified originating from …
Bioavailability of antihypertensive lactoferricin B-derived peptides: Transepithelial transport and resistance to intestinal and plasma peptidases
The transepithelial transport of the angiotensin I-converting enzyme (ACE)-inhibitory and antihypertensive lactoferricin B (LfcinB)-derived hexapeptide LfcinB20-25 (RRWQWR) and of its two main fragments RWQ and WQ were investigated using a human intestinal cell (Caco-2) monolayer. The three peptides were susceptible to the action of brush-border peptidases. Intact LfcinB20-25 was not transported across Caco-2 whereas RWQ and WQ were both absorbed through the cell monolayer. Apparent permeability (Papp) values for absorptive transport across the monolayer were 0.7×10-8cms-1 (RWQ) and 3.9×10-8cms-1 (WQ). The effect of pathway-selective inhibitors on peptide absorption suggested paracellular d…
