Biotechnological preparation of gelatines from chicken feet

Original language description

In the European Union (EU), about five tons of poultry by-product tissues are produced every year. Due to their high collagen content, they represent a significant raw material source for gelatine production. The aim of the paper was the biotechnological preparation of gelatine from chicken feet. The influence of selected process factors on the gelatine yield, gel strength, viscosity, and ash of gelatine was observed; a two-level factor design of experiments with three variable process factors (enzyme addition, enzyme treatment time, and gelatine extraction time) was applied. After grinding and separating soluble proteins and fat, the purified raw material was treated in water at pH 7.5 with the addition of endoprotease at 23 degrees C and after thorough washing with water at 80 degrees C, gelatine was extracted. By the suitable choice of process conditions, gelatine with high gel strength (220-320 bloom), low ash content (&lt;2.0%) and viscosity of 3.5-7.3 mPa&lt;bold&gt;s can be prepared&lt;/bold&gt;. The extraction efficiency was 18-38%. The presented technology is innovative mainly by the enzymatic processing of the source raw material, which is economically, technologically, and environmentally beneficial for manufacturers. Chicken gelatines are a suitable alternative to gelatines made from mammals or fish, and can be used in many food, pharmaceutical, and biomedical applications.
