Enzymatic hydrolysis of protein is a principal method to obtain antioxidant peptides. A yak casein hydrolysate (YCH) was prepared by alcalase and trypsin digestion. An ultrafiltration membrane system used divide the into four molecular weight fractions; YCH-4 (<3 kDa) had highest activity. Fraction separated six subfractions gel filtration chromatography; reverse-phase high performance liquid chromatography (RP-HPLC) then partition sixteen peptide subfractions. Liquid...
Yak whey protein concentrates (YWPCs) have good functional properties, but there is still a gap in the study of their peptides. In this study, peptides were obtained by enzymatic hydrolysis, and bioactivity each ultrafiltration fraction was evaluated using an optimal process. YWPCs isolated purified from yak milk as raw material. Alkaline protease, trypsin, papain used to hydrolyze YWPCs. The protease with highest degree hydrolysis (DH) peptide concentration selected most suitable enzyme....
To extract and utilise the protein in quinoa efficiently, we investigated effect of rate isolate (QPI) extraction by ultrasound-assisted alkaline traditional methods using single-factor experiments Box-Behnken design. The different heat treatment temperature time on QPI functional properties vitro digestion characteristics were also investigated. results showed that optimal conditions ultrasound- assisted process were: ultrasonic 99 min, solid-liquid ratio 1:20 w:v, 47 °C, pH 10, its purity...
The traditional yak yogurt from Gannan Tibetan Autonomous Prefecture harbors a rich microbial community, which strain of Lactiplantibacillus plantarum (Lp. EL2) was isolated. Through whole genome sequencing and probiotic activity assays, the genomic characteristics this its genes related to properties were analyzed. results demonstrate that EL2 exhibits excellent antibacterial effects against Staphylococcus aureus Salmonella, as well favorable antioxidative properties, acid bile salt...
Recently, Lanzhou lily has attracted more attention because of its bioactive components specifically polysaccharides. We studied in vitro the effects Lactobacillus plantarum fermentation on physicochemical properties, chemical structure, and antioxidant activity polysaccharide. The results showed that compared with unfermented polysaccharide (LP-W), molecular weight (Mw) fermented (LPF-W) decreased from 4334 to 1684 kDa, particle size 300.8 ± 6.38 141.9 4.96 nm, solubility increased 72.33...
The aim of this study was to investigate the effects hydrothermal treatment at different temperatures and times on structure functional properties quinoa protein isolate (QPI). QPI investigated by analyzing changes in intrinsic fluorescence spectrum, ultra-violet (UV) Fourier transform infrared spectrum. solubility, water/oil-holding capacity, emulsifying activity, emulsion stability were studied, as particle size thermogravimetric QPI. results showed that average gradually increased with...
