Background and Objective: Recently, several researchers have shown the benefits deriving from probiotic products containing lactobacilli and bifidobacteria in their formulation. The purpose of this study was to develop a probiotic chocolate mousse using milk and soy milk in formulation with regard to survival of probiotic bacteria and sensorial acceptance during 21 days.
Material and Methods: Nine functional probiotic chocolate mousse formulations were produced by milk, milk/soy milk and soy milk and 3 probiotic strains (Lactobacillus acidophilus; Lactobacillus paracasei; Bifidobacteriumlactis). ThepH, acidity, survival of microbial strains, rheological and sensory properties of all treatments were monitored during 21 days refrigerated storage (4°C).
Results and Conclusion: The pH drop rate and acidity increase rate of all samples were significant during 21 days of storage (p≤0.05). There was a significant increase in the probiotic bacteria of all samples during 21 days of storage at 4°C (p≤0.05). However, the rate of probiotics growth was accelerated in formulation prepared with soy milk and milk/soy milk (1:1) in the chocolate mousse at day 7 and 14. Rheological experiment demonstrated that all samples known as viscoelastic solid dessert had shear-thinning behavior. In conclusion, chocolate dessert including soy milk as well as milk was shown to be more effective vehicle for delivery of probiotics, including Lactobacillus acidophilus, Lactobacillus paracasei, Bifidobacteriumlactis.
