Pengaruh Degradasi Enzim Proteolitik Terhadap Aktivitas Angiotensin Converting Enzyme Inhibitor Bekasam Dengan Lactobacillus Plantarum B1765

This research studied the effect of digestive enzyme degradation on the Angiotensin Converting Enzyme Inhibitor (ACEI) activity and the stability of bekasam peptide and ACEI activity. Water extract of bekasam was subjected to pepsin and trypsin. The stability of peptide was measured from the changes of peptide concentration before and after treatment by those enzymes. The stability of ACEI activity was measured by hypuric acid liberated from Hip-His-Leu as ACE substrate and determined by spectrophotometer. The results showed that proteolytic enzyme degradation did not affect the concentration of peptide (p>0,05) and the mean concentration 36.72. It was closely related with the ACEI activity that did not change significantly before and after digestion by pepsin and trypsin (p>0,05) and the mean ACEI activity was 70.73. It showed that ACEI activity of bekasam did not change by the degradation of digestive enzyme
