Abstract
Food-derived exorphins are usually 4–20 amino acid peptides released from food proteins like caseins, whey, gluten, RuBisCo, β-conglycinin, and albumin. They are generated through gastrointestinal digestion, simulated gastrointestinal digestion (SGID), or fermentation. They show structural features that enable them to bind opioid receptors (μ, δ, and κ). These opioid receptors are distributed widely in the central and peripheral nervous system, gastrointestinal tract, some immune cells, and other tissues. These exorphins may act as agonists or antagonists for these opioid receptors. They play various physiological roles in gastrointestinal motility, analgesia, anxiolysis, emotional and behavior development, memory consolidation, blood pressure regulation, prolactin secretion, food and fat intake, hormone release, appetite, and mucous formation. Moreover, these exorphins are correlated with the development of various physiological complications. The conventional opioids show numerous side effects and thereby limit the clinical effectiveness. Food-derived exorphins are safe alternatives for the pharmaceutical and food industry. The merits include oral consumption and bioavailability, safety due to a lack of side effects, and activation at the endogenous opioid receptors. Therefore, these peptides have enough scope in the food and pharmaceutical industry for the development of functional foods and nutraceuticals. Moreover, deeper research with explored signal cascade mechanisms at the cellular and molecular level is needed to explore food exorphins as therapeutic mediators, functional foods, or nutraceuticals for human health promotion.
