Survival of probiotic strains in non-dairy indian spice condiment exhibiting cholesterol reducing properties
The feasibility of a novel formulated spice condiment suitable for delivery of probiotic cultures to consumers has been reported in this study. The spice condiment (pH 4.5, Aw=0.81) exhibited high sensorial scores and stability after storage for 60 days. Lactobacillus casei and Lactobacillus delbrueckii strains were incorporated in the spice condiment and evaluated for survival and expression of important functional characteristics: cholesterol reduction. Both strains survived excellently in the food matrix and sustained simulated gastro-intestinal conditions (viability to 0.3% bile salts and pancreatic enzymes). Probiotic enriched spice condiment fed to experimental mice on high cholesterol diet resulted in significant (p<0.05) lowering of serum total cholesterol, HDLs, LDLs, and triglycerides; moreover; histopathological changes were less intensive. Results of our study suggested the formulated spice condiment as a potential non-dairy food adjunct for delivery of probiotics and may help in managing hypercholesterolaemia.
