摘要：In recent years, it increased the number of studies on extracting the gelatin from different sources and improving the extraction conditions. The physicochemical and functional properties of gelatin are different depending on the composition of amino acids and peptide content. In particular, the gelatin extracted from fish skin constitute an alternative source for halal and kosher products. In previous studies was determined that the gelatin derived from chicken skin had similar physicochemical properties to commercial beef gelatin. In addition, the bioactive peptides obtained by enzymatic hydrolysis of collagen or gelatin are valuable compounds having physiological functions such as antihypertensive/ACE inhibitory activity, cryoprotectant, antidiabetic, antidepression and anti-Alzheimer. In this article has been compiled characteristics of gelatin obtained from various sources and their effects on health of gelatin hydrolysate.
