Contents: The present investigation was carried out to examine the effect of Hibiscus sabdariffa Calyx extract on the physico-chemical properties, sensory attributes, texture and microbial analysis of L. casei incorporated in probiotic yoghurt after manufacture and during storage. Incorporation of Hibiscus sabdariffa Calyx extract into the probiotic yoghurt resulted into decrease in coagulation time by 25 min. The pH ranged from 4.39 to 4.59, TA 0.81 to 1.14%, moisture 3.05 to 3.37 g%, syneresis 18.85 to 24.90 mL/50 g of sample, % inhibition 12.32 to 59.43, TS 21.27 to 24.90 g% and β-galactosidase activity 1.041 to 3.277. The protein content ranged between 4.11 and 4.14 g% while the fat content ranged between 3.43 and 3.49 g%. No major changes in sensory evaluation were observed on the day of manufacture and during storage for 7 days. Sabdariffa added yoghurt showed a higher score in almost all sensory attributes. Microbial analysis showed a total plate count ranging from 1.8x104 to 1.85x107 cfu mL-1. Yeast and mold counts were negligible in the Sabdariffa yoghurts. Thus the study concludes that incorporation of Hibiscus sabdariffa extract in yoghurt improved the total antioxidant property, organoleptic qualities and decreased the exudation of whey proteins (Syneresis). Thus, Hibiscus sabdariffa Calyces has beneficial influence on the quality of L. casei incorporated probiotic yoghurt.
