This study was conducted to examine the effects of eggshell membrane hydrolysates (ESMH) on the anti-inflammatory, anti-wrinkle, anti-microbial activity, and moisture-protection for cosmetic use. Whole ESMH (before fractionation), and fraction I (>10 kDa), fraction II (3-10 kDa), and fraction III (<3 kDa) of the hydrolysates were assessed in this experiment. As lipopolysaccharide (LPS) and IFN-γ caused the inflammation on Raw264.7 cell, whole ESMH and fraction I showed to be effective in inhibiting the induction of cell inflammation depending on the concentration, and also showed outstanding effect to suppress the skin inflammation. Fraction I inhibited collagenase and elastase activities to a greater extent than the other fractions, while all fractions had antibiotic effects at concentrations of 10 mg/disc and 20 mg/disc. In addition, it showed the moisture protection effects of skin on the holding amount and losing amount of moisture in upper-inner arm of the human body with a relatively low loss rate in skin, which confirmed that the hydrolyzed fractions of ESM helps to form the superior protective layer of moisture. It was concluded that ESMH fractions with different molecular weights, especially the 10 kDa fraction, have anti-lipopolysaccharide, anti-IFN-γ-induced inflammation, anti- collagenase and elastase activities, and thus can be used as a cosmetic agent to protect skin.

Background/aims: The quantification of amino acids in the dairy industry is necessary for quality control and for the formulation of functional foods. Thus, the development of enzymatic biosensors requires a detailed study of enzyme kinetics. Parameters such as KM and Vmax are necessary to optimize the sensitivity and specificity of the biosensor.

Amaranthus dubius, commonly known as spleen amaranth, is a valuable nutritional source rich in protein, vitamins, and minerals, especially in regions such as India. This study investigated the protein content of leaves, stems, and seeds, with the seeds showing the highest protein concentration. Protein isolates from seeds were enzymatically hydrolyzed using proteolytic enzymes.

This study investigated white wastewater (WW) as a potential source of antimicrobial peptides, employing hydrolysis with Pronase E followed by separation through electrodialysis with ultrafiltration membranes (EDUF) to increase the value of dairy components within a circular economy framework. The WW hydrolysate was divided into two key fractions: the cationic recovery compartment (CRC) and the anionic recovery compartment (ARC). The EDUF process effectively separated peptides, with peptide migration rates reaching 6.

Background: The Long COVID syndrome is a major global health problem, affecting approximately 10-20% of individuals infected with SARS-CoV-2 virus with many remaining symptomatic beyond one year. Fatigue, reduced exercise tolerance and hyperlactataemia on minimal exertion have led to the suggestion of a bioenergetic defect. We hypothesised that mitochondrial dysfunction is a pathological feature in Long COVID cases and would correlate with clinical outcome.

Eggshell membrane (ESM), a protein-rich byproduct of the egg processing industry, contains latent bioactive sequences with physiological relevance, but remains largely underutilized. To evaluate its potential as a novel source of dipeptidyl peptidase-IV (DPP-IV) inhibitory peptides, ESM was enzymatically hydrolyzed using five proteases, among which alkaline proteases exhibited the most effective hydrolysis. The resulting hydrolysates were systematically assessed for DPP-IV inhibitory activity, amino acid composition, and peptide sequence characteristics.
