Antipepsin, antitrypsin and antichymotrypsin activity was determined in seed extracts of 26 plants consumed by humans and animals (small bean, broad bean, pumpkin, kidney bean, charlock, pea, buckwheat, barley, maize, flax, lupine, poppy, almond, peanut, hazel, walnut, oat, millet, wheat, rice, rape, sunflower, lentils soya bean, vetch, rye). Antipepsin activity is found in the seeds of small bean, pumpkin, flax, peanut, walnut, oat, wheat, sunflower, lentils and soya bean. Antitrypsin and antichymotrypsin activities are of different intensity in seed extracts of all examined plants.

Antioxidants play an important role in maintaining health and enhancing food stability by neutralizing free radicals. This study aimed to extract antioxidant peptides from white-feathered chicken bones through enzymatic hydrolysis, optimize the enzymatic hydrolysis conditions, and further investigate the relevance between the amino acid composition, molecular weight, and antioxidant activity of the resulting chicken bone hydrolysate. Alcalase was the most effective enzyme for hydrolyzing cooked chicken bones compared with papain, pepsin, and trypsin, yielding hydrolysates with the highest DH and ABTS radical scavenging activity.

α-amylase can effectively inhibit the activity of digestive enzymes and alter nutrient absorption. The impact of ovum hydrolysates of sea cucumbers on α-amylase activity was investigated in this study. The protein hydrolysates generated using different proteases (pepsin, trypsin, and neutral protease) and molecular weights (less than 3000 and more than 3000) were investigated.

Article Synopsis
  • The study successfully developed antimicrobial peptides (AMPs) from quinoa using mixed-bacteria fermentation, which showed high antibacterial activity and stability.
  • Among the 9 peptide fractions analyzed, F1 was identified as the most effective in inhibiting bacterial growth in apple juice, particularly against Escherichia coli and Staphylococcus aureus.
  • The specific peptide AGAAPE demonstrated significant stability and resistance under various conditions, and its antimicrobial action was attributed to damaging bacterial membranes, making it a potential solution for preserving fresh juice.

Background: Bacillus subtilis AU-2, isolated from the gut of Tribolium castaneum, was used for protease production. The purified protease was evaluated for its potential in food-related applications including meat tenderization, milk coagulation, and the preparation of enzymatic soybean hydrolysates. Enzymatic hydrolysis of soy protein is an effective method for producing protein hydrolysates with optimal techno-functional properties.
