Bioactive peptides are essentially fragments of larger proteins that exhibit specific biological activities beyond basic nutrition作者：E Vargas-Bello-Pérez·2019·被引用次数：110—Here we consider a third aspect, namely, the potential forpeptidesderived frommilkproteins to havebioactiveactivities when consumed.. In milk, these peptides originate from major protein fractions like casein and whey2. Production ofbioactive peptidesbiologically active peptides can be produced from precursormilkproteins.. Their "bioactivity" is unlocked when these larger proteins are broken down, either naturally during digestion in the gut, through food processing techniques like fermentation, or via enzymatic hydrolysis作者：R Nagpal·2011·被引用次数：385—Milkproteins are the most important source ofbioactive peptides, though other animal as well as plant proteins also contain potential .... The resulting peptides, typically composed of 2 to 20 amino acid residues, possess unique sequences that interact with various biological targets, leading to a cascade of beneficial effects.
The scientific literature reveals a wide array of health benefits associated with milk bioactive peptidesBioactive peptidesfrommilkproteins have many biological activities such as antimicrobial, antihypertensive, antithrombotic, antioxidant, mineral binding, .... These activities are often demonstrated in vitro and in animal studies, with growing evidence from human trials.
* Antihypertensive Effects: A prominent area of research focuses on the ability of certain milk peptides to help regulate blood pressure. These peptides can act as ACE-inhibitors, similar to how some blood pressure medications work, by blocking the angiotensin-converting enzyme that plays a role in constricting blood vessels.Functional attributes of bioactive peptides of bovine milk ... This mechanism contributes to vasodilation and a potential reduction in blood pressure.
* Antioxidant Properties: Milk bioactive peptides can scavenge free radicals, thereby protecting cells from oxidative damage. This antioxidant capacity is crucial in combating chronic diseases linked to oxidative stress, such as cardiovascular disease and aging.
* Antimicrobial Activity: Some peptides derived from milk have demonstrated the ability to inhibit the growth of various pathogenic bacteria. This natural defense mechanism can contribute to gut health and potentially bolster the immune system's ability to fight infections作者：H Dhar·2024·被引用次数：26—This article presents a comprehensive review on well documented antimicrobial, immunological, opioid, and anti-hypertensive activities of bovine milk peptides..
* Immunomodulatory Effects: Certain milk peptides can influence immune responses, either by stimulating or suppressing immune cells作者：R Nagpal·2011·被引用次数：385—Milkproteins are the most important source ofbioactive peptides, though other animal as well as plant proteins also contain potential .... This suggests a role in modulating inflammation and enhancing the body's defense mechanisms.
* Opioid Activity: Some peptides, like beta-casomorphins, can interact with opioid receptors in the body, potentially influencing mood, pain perception, and gastrointestinal function.
* Mineral Binding: Peptides can also play a role in enhancing the bioavailability of minerals like calcium and zinc, aiding in their absorption and utilization by the body, which is particularly important for bone health.
Milk bioactive peptides are naturally present in milk and dairy products. However, their concentration and accessibility can be significantly influenced by various factors:
* Fermentation: The microbial action during the fermentation of milk products, such as yogurt and cheese, is a key process for releasing bioactive peptides from their precursor proteins.
* Enzymatic Hydrolysis: Specific enzymes can be used to deliberately break down milk proteins, generating a targeted profile of bioactive peptides with enhanced functional properties. This is often employed in the production of specialized ingredients.
* Gastrointestinal Digestion: Even without specific processing, the natural digestion of milk proteins in the human gut liberates many bioactive peptides.New insights into multifunctional aspects of milk derived ...
The recognized health benefits of milk bioactive peptides are driving their incorporation into a variety of products. They are increasingly found in:
* Functional Foods: Yogurts, fermented milk drinks, cheeses, and specialized infant formulas often feature added milk bioactive peptides to enhance their health attributes.
* Nutraceuticals and Dietary Supplements: Capsules, powders, and beverages designed for specific health outcomes, such as blood pressure management or immune support, utilize these peptides as key ingredients.
* Cosmetics: Some research explores the use of milk peptides in skincare products for their potential anti-aging and skin-conditioning properties.New insights into multifunctional aspects of milk derived ...
