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 aredifferent depending on the composition of amino acids and peptide content. In particular, the gelatinextracted from fish skin constitutes an alternative source for halal and kosher products. In previousstudies was determined that the gelatin derived from chicken skin had similar physicochemical propertiesto 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/ACEinhibitory activity, cryoprotectant, antidiabetic, antidepression and anti-Alzheimer. In this article hasbeen compiled characteristics of gelatin obtained from various sources and their effects on health of gelatin hydrolysate
