Abstract: This study aimed to evaluate the effect of the degreasing process, using cattle bones as raw materials on the quantity and quality of collagen extracted. Raw materials in this study were scapula bones (os scapula) of Bali cattle. Degreasing treatments included various concentrations of ethanol solutions, with two processing times. Data were analyzed by ANOVA; treatment differences were further tested by the Duncan Multiple Range Test where the significant effect was found in the ANOVA. The results showed that application of ethanol with a concentration of 60% and the time process of 1 day produced better physicochemical properties of the collagen extract, however. Functional properties of products collagen extract from the overall combined treatment showed identical results.
