An Investigation of Effects of Whey Protein Hydrolysate on Yogurt Starter Cultures and Probiotic Bacteria in Ayran

Abstract

This study aims to monitor the effect of whey protein hydrolysate (WPH) on the growth and activity of probiotic bacteria (Streptococcus thermophilus, Lactobacillus delbrueckii spp. bulgaricus, Lactobacillus acidophilus, and Bifidobacterium lactis) in ayran, and also to enhance the functionality of ayran by addition of the probiotics. Effects of WPH and probiotics addition as 0%, 0.25%, 0.5% and 1% on the growth of probiotic bacteria were studied before and after the fermentation and 7th, 14th, and 21st days of the storage. WPH and probiotics had a significant effect (p<0.05) on the growth of target microorganisms and the biochemical variables. The addition of WPH and probiotics significantly (p<0.05) increased the growth of probiotics compared to the control after the fermentation up to the 21st day of storage. The samples containing different WPH levels had lower (p<0.05) pH levels compared to the control during the study time. The mixing of WPH at 1% had the highest total solids and protein content compared to the control samples. The WPH decreased (p<0.05) the viscosity and Hunter color parameters in added the samples. Results indicated that WPH had great potential for enhancing the growth of probiotic bacteria and the nutritional of ayran.
