N2 - Sensory evaluation is an important task for manufacturers to improve the product quality of new functional fermented milk drinks (FFMD) containing angiotensin-converting enzyme inhibitory (ACE-I) bioactive peptides produced during milk processing by enzymatic/mechanical hydrolysis. Herein, a fermented reconstituted skim milk (RSM) was made with Lactobacillus helveticus supplemented with Flavourzyme® using a bioreactor to improve cell viability and levels of ACE-I bioactive peptides. Sensory evaluations of three different fermented RSM drink samples were conducted by 20 trained panellists. There were no significant differences in flavour, bitterns, appearance and acceptance of FFMD compared to the commercial product Yakult®. Addition of sucrose and flavour provided positive changes in terms of acceptability by consumers.
