CONTRIBUTION A L’AMELIORATION DE L’APTITUDE FROMAGERE DU LAIT CAMELIN : ETUDE DES CONDITIONS DE CONSERVATION DES ENZYMES GASTRIQUES CAMELINES

Abstract

In this study, we performed an extraction of coagulant enzymes (ECD) from abomasum whole camel adults (between 8 and 9 years) and studied the effect of four methods of preservation of these extracts in order to seek optimal method for preserving their activities, and proteolytic coagulant. The camel milk used in this work has a pH, density and titratable acidity, respectively equal to 6.65 ± 0.13, 1.027 ± 0 and 21.3 ± 1.44. The protein content of extracts of gastric coagulants camel is equal to 735 g / ml with an extraction yield of 3%. The results show that EDC frozen for 14 weeks, showed the best results on both the coagulant that proteolytic activity is 0.128 UP and an optical density of 0.446 respectively.
