  • Method for improving Vitamin D stability in liquid nutritional products
    Patent number: 5456926
    Abstract: A method is disclosed for improving the stability of Vitamin D in liquid nutritional products which contain hydrolyzed protein or free amino acids as nitrogen sources. Vitamin C is added before or after a preliminary heat treatment of the liquid nutritional product and at a concentration exceeding 300 mg/l, such that the initial concentration of Vitamin C is at least 300 mg/l during the shelf-life of the liquid nutritional product. An emulsifier is added to the liquid nutritional product prior to preliminary heat treatment, the emulsifier being a diacetyltartaric acid ester of monoglycerides and diglycerides. Cystine is added following the preliminary heat treatment.
