In this thesis peptides with biological activity have been separated and identified, mainly peptides with antihypertensive activity in commercial fermented milk with Streptococcus thermophilus and Lactobacillus acidophilus, during refrigerated storage. This thesis is structured in three parts. In the first part analysis of soluble peptides determination by Lowry technique was...
Milk protein derived peptides could exert physiology functions in human body, mainly antihypertensive activity by the inhibition of the Angiotensin Converting Enzyme (ACE). These peptides can be liberated by proteolytic microorganism during fermentation. In this work the effect of pH on the production of bioactive peptides during milk fermentation by...
