Bioactive peptides showing Angiotensin-I-Converting Enzyme inhibitory (ACEi) activity can control blood pressure. They be produced from various protein sources, including fish gelatin. This article provides a systematic review and meta-analysis on gelatin extraction, conditions of enzymatic hydrolysis, characteristics ACEi peptides, effect hydrolysis procedure peptides. Fish preparation uses so...

BACKGROUND The major types of commercially available gelatin hydrolysates are prepared from mammals or fish. Dietary gelatin hydrolysates from mammals were reported to improve bone mineral density (BMD) in some animal models. In contrast, there is limited study showing the effects of dietary gelatin hydrolysates from fish on BMD. The quantity and structure of peptides in the plasma after oral a...

23 The rheological and functional properties of gelatin from the skin of bigeye 24 snapper (Priacanthus hamrur) fish were assessed. The protein content of dried gelatin 25 was 94.6% and moisture content was 4.2 %. The amino acid profile of gelatin revealed 26 high proportion of glycine and imino acids. The bloom strength of solidified gelatin was 27 108 g. The average molecular weight of fish s...

We report a simple, effective and green way for the fabrication of gelatin-graphene-like BN nanocomposites for gas barrier applications. The reinforcement effect of graphene-like BN on the gelatin properties is discussed. The obtained graphene-like BN nanocomposites show good dispersion in the gelatin matrix and remarkable capability to improve the crystallinity and the barrier properties of ge...

Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...

This report investigates the comparative in vitro controlled release and transfection efficiencies of pDNA-lipofectamine complex (lipoplex) and pDNA-poly(ethylene imine) complex (polyplex), from a biodegradable polycaprolactone (PCL) film. The effect of molecular weight of gelatin used as a porogen on in vitro release and transfection efficiency was also studied. A sustained release profile was...

The aims of this study were to examine the effect of salts (CaCl2, CaSO4 and MgSO4) on the rheological and thermal properties of gelatin extracted from the skins of tropical fishes, sin croaker (Johnius dussumeiri) and shortfin scad (Decapterus macrosoma). It was found that the melting temperatures of fish skin gelatins were increased by 1.5 times as compared to bovine gelatin which was only in...

The objectives of this research were to improve the film-forming properties of Channel Catfish Ictalurus punctatus skin gelatin (CSG) by cross-linking with transglutaminase (TG), determine and optimize the TG reaction time, and characterize the mechanical and barrier properties of CSG edible film. Cross-linking of CSG was performed by TG for 0, 10, 20, 30, and 40 min at 50°C, and the reaction w...
