Summary: The study aims to fractionate antibacterial peptides from pepsin-hydrolyzed egg yolks using flash chromatography and determine their mode of action. Fraction 6 (F6) exhibited antibacterial activity against Staphylococcus aureus and Salmonella typhimurium. The peptides caused DNA leakage, cell membrane disintegration, and cell ruptures, indicating their potential as antistaphylococcal agents.

Summary: This study investigated the antioxidant and antidiabetic properties of soursop leaf biomass hydrolysates (SLH). The results showed that flavourzyme-generated SLH had the highest peptide content compared to alcalase-and trypsin-generated SLH. SLH demonstrated strong antioxidant and antidiabetic activities, with 14 identified bioactive peptides, two of which showed high binding probability to alpha-glucosidase and alpha-amylase. These findings suggest that SLH could be used for diabetes prevention.

Summary: Obtaining peptides with antioxidant properties by non-enzymatic hydrolysis has been investigated in this study. Delipidated egg yolk granules were hydrolyzed with trypsin and with a non-enzymatic method using sub-critical water hydrolysis. The results showed that sub-critical water hydrolysis under a nitrogen stream produced peptides with good antioxidant capacities compared to enzymatic hydrolysis, while the oxygen environment in sub-critical water hydrolysis reduced the antioxidant capacities of the peptides.

Summary: In this study, a novel egg yolk protein hydrolysate (EYPH) with high Ca2+-binding ability was prepared, and the interaction between EYPH, phytic acid (PA) and calcium ions (Ca2+) and their influence on protein digestibility and Ca2+ transport were investigated. The results showed that these interactions occurred at pH 7.0, but only the binary interaction between EYPH and PA was observed at pH 2.0. These interactions significantly affected protein digestibility and Ca2+ transport in vitro. These findings provide important insights for studying the interactions, protein behavior, and Ca2+ uptake of complex mixtures.

Summary: The study showed that ultrasound-assisted process (UAP) could increase the yield and protein recovery of protein extracted from Bombay locusts (BL), improve solubility without affecting foaming capacity and stability, but impact emulsion activity and stability. UAP also enhanced BL with high radical scavenging activities and good electron donating ability, affecting the isoelectric point and molecular characteristics compared to typical process (TP).

Summary: The egg yolks of birds contain important materials for embryo development and offspring viability. The laying date of birds can vary, which can be influenced by environmental factors. In this study, the yolk small molecule compounds of Asian Short-toed Lark were found to vary between early and late broods, possibly due to differences in environmental temperature and food intake.

Summary: Plant feed additives, including hemp and its compounds, have shown desirable effects in improving animal health and welfare. Among them, cannabidiol has been found to effectively relieve pain and reduce inflammation in animals, making it a potential option for improving animal welfare, particularly in poultry production. Despite legal restrictions in some countries due to the presence of psychoactive THC, many countries have legalized hemp in recent years. Cannabidiol, a non-psychoactive compound, has anti-inflammatory, antioxidative, analgesic, and anti-depressant effects. This review explores the various aspects of cannabidiol use and its potential benefits in animals and humans.

Summary: This study aimed to obtain chitooligosaccharides (COS) from chitosan (CH) with improved functional properties. Two different enzymes, commercial cellulase (CL) and the dedicated enzyme chitosanase (CS), were used for comparison. Results showed that the enzymes had different cleavage mechanisms. The fractions LMF and NF had improved solubility compared to HMF and CH samples, and LMF was sensitive to high temperatures. COS were a mixture of oligomers with different degrees of polymerisation. LMF had lower DPPH radical scavenging activity compared to HMF and NF.
