    Major Research Accomplishments

    • Diversification of probiotic foods i.e., beyond the traditional fermented dairy products i.e., towards the non-fermented and heat-treated food product categories, i.e., development of symbiotic milk chocolate using microencapsulated probiotics. Biodynamic milk chocolate with encapsulated probiotics is a new addition to the growing list of functional foods.
    • Development of “synbiotic kulfi” by incorporating probiotic lactobacilli.
    • Development of “functional Quarg cheese” by fortifying with dietary fiber and probiotics.
