Typically comprising 3 to 20 amino acids, these peptides remain inert within parent proteins until activated through enzymatic hydrolysis during food processing or digestion. To impart health benefits, they must traverse the gastrointestinal barrier and withstand enzyme degradation.
Numerous bioactive peptides present in foods such as milk, eggs, soya, fish, and meat have been extensively studied, particularly for their antihypertensive properties, addressing a significant risk factor for cardiovascular diseases.

Source of Bioactive peptides

Bioactive peptides are sourced from both plants and animals. Cereal grains like wheat, barley, rice, and oats contain peptides with diverse activities, including ACE inhibition and anti-thrombotic, antioxidant, and hypotensive effects. Bovine milk, cheese, and dairy products, particularly during digestion, release biologically active peptides.

Fermented milk can lower blood pressure. Eggs, especially the yolk, exhibit high antioxidant activity. Meat and fish-derived peptides demonstrate in vitro activities such as antihypertensive, antioxidant, antimicrobial, and antiproliferative effects. Overall, these sources offer a rich array of bioactive peptides with various health benefits.

Pharmacological properties of bioactive peptides

Bioactive peptides, influenced by factors such as amino acid composition, length, and hydrophobic/hydrophilic characteristics, play a pivotal role in disease prevention and positive physiological effects. Milk proteins and casein-derived peptides act as antioxidants, thwarting essential fatty acid peroxidation. Antimicrobial peptides (AMPs), notably from casein, inhibit microorganism growth. Immunomodulatory properties are observed in proteins and peptides from diverse sources like eggs, milk, soy, and plants, contributing to anti-inflammatory effects. Cytomodulatory properties hint at potential anti-cancer effects by targeting malignant cells.

Metabolically, these peptides regulate conditions like diabetes, obesity, hypertension, and dyslipidemia. Notably, egg white peptides showcase anti-diabetic and α-glucosidase inhibitory properties, underscoring their significance in metabolic regulation and disease prevention.

Synthesis and Production of Bioactive Peptides

Recent years have witnessed a significant surge in interest regarding the synthesis and production of bioactive peptides. To enhance their yield and bioavailability, researchers delve into an array of methods. Notably, during food processing, enzymatic hydrolysis continues to hold its position as the primary technique for generating these valuable bioactive peptides.

The progress in biotechnology has furthered the development of engineered enzymes for targeted peptide release, which ensures a production process that is more controlled and efficient. Additionally, through the use of innovative techniques like microbial fermentation and enzymatic transformation, bioactive peptides with specific health-promoting properties are generated.

Bioavailability Challenges and Solutions

Bioactive peptides promise substantial health benefits, yet their bioavailability presents a formidable challenge. Numerous hurdles impede many of these peptides from crossing the gastrointestinal barrier, and they may even experience enzymatic degradation prior to reaching their intended target sites. Consequently, researchers are fervently investigating encapsulation methods and nanotechnology applications.

Moreover, they’re actively developing delivery systems with the aim of augmenting both stability and bioavailability for such crucially important biomolecules. For instance, nanoencapsulation promises to protect bioactive peptides during digestion and enhance their release at specific body locations. This process amplifies the therapeutic effects of these substances.
