Abstract/Summary

-
The aim of this study was to analyze the effect of different amounts of barley bran (0.3%, 0.6%, 0.9%, and 1.2%) on the viability of Lactobacillus acidophilus and the physicochemical and sensory properties of low‐fat yogurt during storage period (28 days). Results showed that L. acidophilus number and viscosity in samples containing barley bran was significantly higher than the control group (p < .05). High levels of barley bran (1.2%) decreased sensory prosperity scores and led to viscosity increment; although sensory prosperity scores of samples containing 0.6% barley bran did not show significant difference with control sample, while the number of L. acidophilus in this treatment was higher than minimal acceptable level (106 CFU/g). Therefore, level of 0.6% of barley bran is recommended for symbiotic yogurt production. According to the present study, a positive correlation was observed between barley bran concentrations in the yogurt with L. acidophilus number.
