Abstract: | Gelatin was made by hydro/izing shark skin with acetic acid solution (type A gelatin) and sodium hydroxide sO/liion (type B gelatin). The gelatin was extracted t;om the collagen in water at 8(}Oe for two hours and dried by vacuum oven to obtain gelatin powder. Rheological properties of shBlk skin gelatin wem examined during so/ and gel formation. Gelatin gel strength (measured as bloom), viscosly of gelBIin sols, syneresis snd decle8se of hiflmess of gel form wem measured and comp8led with the commetcfal gelatin (pork, beef WId fish gelatin). The dependence of type A gelatin gel strength upon the gel concentration, pH, NaGl snd sucrose wem simHar to those of the type B gelatin. The type 8 gelatin gel stTel/fih was similar to the commercial gelatin, i.e. 200 bloom. Shark skin gelatin showed higher viscosity WId syneteSis rate than that the commercial one. That fact extends the possible chaises of shark skin gelatin for many snd varied applications. |
