Abstract

This study aimed to develop a new type of yogurt through addition of carrot juice. Yogurt is a fermented milk product obtained from fermentation of Lactobacillus bulgaricus and Streptococcus

thermophilus strains. The effect of carrot juice at different levels (0%, 8%, 16%, 24%) on sensory properties and the viability of probiotic bacteria in yogurts during storage (21 days) at refrigerated temperature (4°C) was evaluated. The yogurt supplementation with 24 % carrot juice significantly improves the stability of the lactic acid bacteria, that contained the recommended levels of 107 cfu/g) probiotic bacteria at the end of 21-days shelf life. The yogurt with 24% carrot juice was the most appreciated (7.07 points), followed by the classic yogurt (6 points), yogurt with 8% (5.28 points) and yogurt with16% carrot juice (5.5 points).
