Biologically active peptides with tyrosinase inhibitory activity may be important raw materials in the field of whitening foods. Gastrointestinal digestion was employed to obtain components higher from grass carp fish scale gelatin hydrolysates. The results revealed that product had stronger after gastrointestinal than before. digested products were screened using bioaffinity ultrafiltration for first time, yielding 6 peptides. As a reversible competitive inhibitor, FTGML showed highest IC50...
In this work, the effect of addition γ-polyglutamic acid (γ-PGA) on rheology, physicochemical properties, and microstructure fish gelatin (FG) emulsion gel was investigated. Samples were evaluated for rheological behavior stability prior to gelation. The mechanical properties water-holding capacity (WHC) determined after further examined using confocal laser scanning microscopy (CLSM). results indicated a gradual increase in apparent viscosity gelation temperature at higher concentration...
Dynamic high pressure microfluidization (DHPM) was applied to treat fish gelatin from bighead carp (Hypophthalmichthys nobilis) scale. The effects of various pressures 40 160 MPa on the functional properties and structural characteristics were evaluated. results showed that DHPM significantly improved emulsifying foaming properties, as well in vitro pepsin digestibility. Surface hydrophobicity treated considered be highly correlated activity with R2 .99933. could not change gel strength...
Peptide Phe-Thr-Gly-Met-Leu (FTGML) is a bioactive oligopeptide with tyrosinase inhibitory activity derived from gelatin hydrolysate of grass carp scales. Previous studies have shown that FTGML addition can effectively inhibit mushroom in vitro, and also has some effect on the inhibition melanogenesis zebrafish vivo, but underlying mechanism not fully understood. In this study, we used to treat B16F10 melanoma cells, found significant melanin synthesis. Interestingly, treatment showed strong...
Bioaffinity ultrafiltration combined with LC-Orbitrap-MS/MS was applied for the first time to achieve rapid screening and identification of tyrosinase inhibitory peptides (TYIPs) from grass carp scale gelatin hydrolysates. The binding mode TYIPs investigated by molecular docking technology. whitening effect further studied evaluating activity melanin content in mouse B16F10 cells. Four new were screened hydrolysates, among which DLGFLARGF showed strongest inhibition an IC50 value 3.09 mM....
The effects of γ-polyglutamic aid (γ-PGA) on the gelling properties and non-covalent interactions fish gelatin were investigated. gel strength melting temperature gradually increased, with increasing γ-PGA concentration, although there was no significant change when concentration greater than 0.04%. As electrostatic interaction increased hydrophobic between molecules decreased. system comprised concentrations 0.04 0.06% showing a strong hydrogen bond. When from 0 to 0.04%, more phenolic...
To investigate the effect of high-frequency chest wall oscillatory expectoration system (HFCWO) on pulmonary rehabilitation and cortisol function in patients with severe acute exacerbation chronic obstructive disease (AECOPD).
Summary This work investigated gelling properties and structural characteristics of fish gelatin (FG) modified by four different molecular weights γ‐polyglutamic acid (γ‐PGA) with 700, 1000, 2000 3000 kDa, respectively. Gelation‐melting transition temperature gel strength increased the increase weight in γ‐PGA. Especially, γ‐PGA kDa made strength, gelation melting temperatures reaching to 628.08 g ( P < 0.05), 22.30 °C 30.17 Non‐covalent interactions existed FG Such as, new hydrogen bonds...
Abstract BACKGROUND Emulsions are thermally unstable systems. This research aimed to investigate the thermal stability of fish gelatin (FG) oil‐in‐water emulsions in presence poly‐γ‐glutamic acid (γ‐PGA) as an additive after heat treatment. The study assessed how γ‐PGA influences FG over time, focusing on their properties, structure, and food application potential. RESULTS incorporation significantly enhanced emulsions, preserving morphology heating. containing 0.1% showed no significant...
