Antioxidants, polyphenols, phytonutrients, and health-promoting foods.
Among water-soluble dietary fibers, β-glucans possess the most rigorous authorized clinical health claims (validated by both EFSA and the US FDA). Occurring as mixed-linkage (1→ 3),(1→ 4)-β-D-glucans within cereal endosperm and aleurone walls (oats, barley), or as branched (1→ 3),(1→…
In functional food design and nutraceutical formulation, deploying isolated single bioactive phytochemicals frequently yields disappointing clinical outcomes due to poor intestinal permeability and rapid metabolic clearance. Conversely, combining synergistic phytochemical classes co-evolved within natural plant matrices establishes dual pharmacodynamic targeting.…
In classical nutritional biochemistry, dietary carbohydrates were categorized primarily as hydrolyzable energy sources yielding systemic glucose via pancreatic alpha -amylase and brush-border glucoamylase. However, specific starch architectures resist upper gastrointestinal enzymatic cleavage, entering the cecum and colon intact to undergo…
Dietary proteins function beyond macronutrient nitrogen sources: they operate as physiological cryptides, encoding short encrypted sequences within their primary polypeptide scaffolds. When liberated via targeted enzymatic hydrolysis or microbial fermentation, these 2-to-20 amino acid oligopeptides—designated as Bioactive Peptides—bind physiological receptors…
Marine ecosystems synthesize structurally specialized lipophilic bioactives devoid of terrestrial botanical analogs. Primary among these are esterified polar forms of long-chain polyunsaturated fatty acids (EPA and DHA) and the lipid-soluble xanthophyll keto-carotenoid “astaxanthin,” biosynthesized by microalgae (Haematococcus pluvialis) and bioaccumulated…
The upper human gastrointestinal enzymatic arsenal (salivary and pancreatic alpha -amylases, brush-border glucoamylases) possesses stereospecific capacity exclusively to cleave alpha -1,4 and alpha -1,6 glucosidic linkages. Plant-derived fructans (inulin and fructooligosaccharides – FOS) are constructed from D-fructose monomers linked via…
The primary hurdle in functional food formulation involves the severe vulnerability of bioactives (viable probiotic consortia, marine polyunsaturated fatty acids, fragile polyphenols) to environmental stresses (thermal processing, oxygen exposure, photo-oxidation) and harsh gastrointestinal frontiers (gastric hydrochloric acid pH 1.5, pepsin,…
Punica granatum L. (pomegranate) is scientifically recognized as the preeminent natural matrix of high-molecular-weight hydrolyzable tannins, specifically ellagitannins. While the edible seeds (arils) supply anthocyanins and organic acids, the industrial extraction of whole fruit introduces massive quantities of punicalagin anomers…
