Probiotic forzen yogurt

Abstract

Recent trends show that consumers have been searching for functional foods to improve bodily functions and overall health. The purpose was to develop new formulations of frozen yogurt, a food product widely accepted among health conscious consumers, by adding probiotics (Lactobacillus spp.). The developed frozen yogurt formulae were as follows: Formula 1 with no probiotics, Formula 2 containing 3%w/w of probiotics, and Formula 3 containing 4%w/w of probiotics. The survival rate of probiotics in Formula 2 and Formula 3 at Day 30 was 33.89% and 26.67%, respectively. Sensory evaluation was carried out among 60 panelists, using the 9-point hedonic scale method for food acceptance. According to Analysis of Variance, the mean scores of these three formulae were not significantly different (p > 0.05). Formula 1, 2, and 3 obtained the mean score of 7.25 (“like moderately” to “like very much”), 6.97 (“like slightly” to “like moderately”), and 7.27 (“like moderately” to “like very much”), respectively.
