Abstract
The purpose of this research was to determine the character of kefir ice cream enrichment with Saccharomyces cerevisiae ATCC 36858 in various concentration. The study was conducted using a complete randomized design with 4 treatments (T0=0%; T1=0.25%; T2=0.5%; T3=1% S. cerevisiae ATCC 36858 (w/v)) and 4 repetitions. The results of the study were processed using ANOVA and DMRT. The treatment increases acidity, ethanol, viscosity and decreases the pH value, overrun, and melting rate of the product (p<0.05). The micro-nutrients (C, O, K, Ca, P, Cl, S, Na, Mg, Si) and macro nutrients (protein and fat) has changed (p>0.05). The lactic acid bacteria and yeast content has decrease of 10^5 CFU/mL during 28 days of storage. T2 has a good overall acceptance value with flavor and texture favored by panelists.
