  • Riboflavin composition and method for production
    Patent number: 5034389
    Abstract: The invention involves a riboflavin composition comprising about 70% to about 90% by weight riboflavin and about 10% to about 30% by weight of a bulking agent selected from the group consisting of yeast, mold, fungi, bacteria and a mixture thereof, and having a bulk density greater than a riboflavin product having a purity of at least about 90% by weight. The riboflavin composition has improved flowability and reduced electrostatic charge relative to riboflavin products having a purity of at least about 90% by weight. The invention also involves a method for producing the riboflavin composition. The method comprises the steps of mixing riboflavin having a purity of at least about 90% by weight, a volatile, non-toxic liquid, and the bulking agent to produce a blend, and drying the blend.
