Chemical modification of gelatin with vaporized hexanal.

Chemical modification of maleic anhydride polymers with carbazole

Maleic anhydride (MAN) copolymers with methyl methacrylate(MMA), ethyl methacrylate(EMA), methyl acrylate(MA), ethyl acrylate (EA) and buthyl acrylate (BA) ( in a 1:1 mole ratio) were synthesized by free radical polymerizations method under vacuum -azobis(isobutironitrile)(AIBN) as an initiator of reaction at 701C. The copolymer compositions were determined using related 1H NMR spectra techni...

Chemical Modification of Cold Water Fish Gelatin using Natural Phenolic Cross-linker Caffeic acid

Nowadays use of edible films and coatings is increasing due to their biodegradability properties. Fish gelatin obtained from fish skin wastes can be used as an appropriate protein compound for preparing the edible films. It can be also replaced pork gelatin. In this study, films were prepared from fish gelatin and phenolic compound caffeic in four levels of 0%, 1%, 3% and 5% at pH>10, temperatu...

Physico-chemical characteristics of gamma-irradiated gelatin

This article reports the effects of gamma irradiation (dose ranges 0.1-10 kGy from 60Co source) on the characteristics of solid gelatin and the physico-mechanical, microstructural and bioactive properties of the scaffold prepared from irradiated gelatin solution. FTIR, intrinsic viscosity, bloom strength, thermal properties, SEM, tensile properties, water uptake ability and antimicrobial activi...

The chemical composition of snail gelatin.

1. The effects of a dietary supplement of cholesterol on liver vitamin A stores have been determined for normal and castrated young male rats. 2. When vitamin A and cholesterol were given in the diet together, liver vitamin A stores were significantly lowered to the same degree in normal and castrated animals. No significant changes in kidney or plasma vitamin A levels were observed. 3. If the ...
