Bioactive Peptides: Origins, Extraction Methods, and Production Processes

healthcaredesignnews.comBioactive Peptides (BPs) can be defined as protein fragments with beneficial effects on physiological conditions or processes, with potential health-promoting properties. A database known as “Biopep” currently holds over 1500 reports on specific BPs; in order to gather sufficient proof that bioactive peptides are effective functional agents in treating and preventing diseases, rigorous clinical trials must be carried out first in order to gather sufficient proof that such functional agents actually do exist.

Lets first explore what bioactive peptides are before exploring their sources, extraction methods and production.

Bioactive Peptides: Origins and Origins of Bioactive Peptides


Proteins are polypeptides with a higher molecular weight; while BP refers to an organic compound composed of amino acids linked together by covalent bonds known as an amide or peptide bond. (MW).

Proteins and peptides are vital macronutrients, serving both as energy sources and as building blocks to form new proteins. A wide range of plant and animal sources have isolated or created bioactive peptides.

Two factors play an important role when selecting food proteins as sources for bioactive peptides:

Add value to abundant underutilized proteins or protein-rich industrial food waste by selecting proteins with specific peptide sequences or amino acid residues that provide clear therapeutic advantages.

Bioactive Peptides: Extraction Processes for Bioactive Peptides


Bioactive peptides can be extracted through either chemical hydrolysis and fermentation or enzyme hydrolysis and fermentation processes.

Studies on new approaches such as microwave, ultrasound-assisted extraction, ohmic heating, pulsed electric fields and subcritical water hydrolysis have been undertaken.

These techniques augment hydrolysis to produce bioactive peptides and physical processes are at the center of these techniques.

Bioactive Peptides: Manufacturing Bioactive Peptides

Yoghurt, milk, cheese, plants, marine species and human saliva can all provide bioactive peptides. Here is an outline of the procedures to create such bioactive peptides:

Enzymatic hydrolysis produces low molecular weight peptides which are effective antihypertensive and antioxidant agents.
Microbial fermentation involves cultivating bacteria or yeast on protein substrates to produce peptides with differing degrees of proteolysis, producing lactobacillus brevis as a powerful ACE inhibitor compared with other lactobacillus strains.
Pharmaceutical Properties of Bioactive PeptidesBioactive peptides have various pharmaceutical properties depending on their N- and C-terminal amino acid type, chain length, charge characteristics and composition.
Food Peptidomics (Food Proteomics) is an emerging field that employs high-resolution techniques to enhance food safety and quality. Milk-derived bioactive peptides possess multiple therapeutic functions such as immunomodulatory, antimicrobial, antioxidant, and inhibitory activities against toxic agents.
Plastering is a protease-induced peptide that can increase the nutritional value of low-quality proteins while improving health and improving wellbeing.

Bioactive Peptides: Concluding Remarks

Bioactive peptides from food proteins hold great promise as an ingredient for functional meals and nutraceuticals, due to their wide array of vital benefits such as anti-inflammatory, anti-cancer, anti-microbial, immunomodulatory and antihypertensive properties.

Conducting comprehensive clinical trials to demonstrate the efficacy of bioactive peptides as functional agents against diseases is of utmost importance, particularly given how consumers have become increasingly aware of the health-promoting advantages offered by nutraceuticals.

When buying peptides for clinical research, it is wise to purchase only top quality peptides from top manufacturers who also offer safe and secure shipping services.
