High pressure, at 250 and 400 MPa, for 10 or 20 min, was applied at either of two stages: during pre-treatment in acid at 10 8C to facilitate destabilisation of acid labile crosslinks, or during extraction in water at 45 8C to accelerate collagen hydrolysis. The resulting gelatins were evaluated in terms of yield of extraction, molecular weight distribution by SDS-PAGE, and viscoelastic propert...

Gelatin is one of the most popular natural polymers which widely used in food, pharmaceutical, biomedical and cosmetic industries. The gelatin has been prepared from different sources such as porcine skin, cattle bone, fish, etc. Depending on type acidic alkali extraction processes A B were obtained. This chapter provides a comprehensive overview preparation base hydrogel. Furthermore, we evalu...

Active films made of chitosan and fish gelatin blends containing 5% (w/wt polymers) tyrosol, ferulic acid or caffeic were prepared by the casting method. The kinetic release was assessed in water 1% (w/v) NaCl solution, at three temperatures (4, 25 32°C). Partition (Kf/S) effective diffusivity (D) modelled which allowed to characterize mechanism. Tyrosol has a faster higher concentration than o...

Fish skin gelatin is an important functional product in the food, cosmetics, and biomedicine industries, establishing a green effective fish extraction method way to obtain high-quality improve its production efficiency. In this study, trypsin was used extract of sea perch, tilapia, grass carp, microstructures these three species were analyzed, with such characteristics as thermal stability, ge...

Abstract Due to its unique properties, collagen is used in various emerging fields such as the pharmaceutical and biomedical device industries, well related fields: nutraceuticals, cosmetics, food, beverages nutritional supplements. Marine gelatin, one of biomaterials involved food medicinal research, denatured produced from acid, alkaline, or enzyme hydrolysis. Gelatin a crucial ingredient for...
