摘要
To optimise the formulation of phytosterol-enriched probiotic yoghurt, the effect of different concentrations of phytosterols, fat and the probiotic inoculation rate on the survival of Lactobacillus acidophilus LA-5, Bifidobacterium lactis BB-12 and physicochemical indices over 14days of storage was explored. Data analysis showed that the phytosterol concentration and fat content were two crucial factors affecting probiotic viability. Addition of phytosterols had no adverse effect on the overall scores for sensory attributes. Regarding maximisation of viability and storage time, the optimum conditions were found to be fat=8.07% (w/v), phytosterol=18g/L, probiotic inoculation rate=71.42mg/L and storage time=12days.
