Study of some Functional Properties of Elastin Extracted from Bovine Leather

Abstract

Abstract The study aimed to detect elastin protein extracted from leftover bovine leather that is not used in other industries, by conducting some tests to identify this protein and its functional properties and the possibility of using it in scientific applications, as the chemical composition tests showed that it contains a high percentage of protein and low percentages of moisture, fat and ash, and some functional properties were conducted to find out the ability of elastin to bind water and oil compared to other studies, studying the structural and chemical characterization of the properties of elastin extracted by FTIR and amide groups extended to elastin, as the results of electron microscopy (SEM) revealed, the shape of elastin fibers showed that they have a structure similar to myofibrillar muscle fibers, except that they are coarser, asymmetric, and have an asymmetric extension, while the TGA test showed that elastin extracted from bovine leather has 5 peaks and fracture peaks for weight loss in percentage as a function of temperature and that elastin gets a weight loss of up to and 44.02% at a temperature of 600 C, while it was shown DSC calorimeter analysis It can withstand a temperature of up to 290 °C.
