  • ACID STABLE BEVERAGES COMPRISING BIXIN
    Publication number: 20180310595
    Abstract: The present invention is directed to an acid-stable bixin form, wherein the bixin is microencapsulated in a matrix of a hydrocolloid, preferably in a matrix of modified food starch. This bixin form can be in the form of an emulsion, a suspension or in form of a powder. The present invention is further directed to a process for the manufacture of such forms, as well as to beverages containing them. These yellow-orange to red-orange beverages are physically stable and color stable.
