  • Colorant compositions and methods of use thereof
    Patent number: 10750761
    Abstract: Natural blue colorant compositions and methods of use thereof are provided. The colorant compositions include at least one acylated anthocyanin, such as a diacylated anthocyanin. The colorant composition can further include a buffer solution having a pH from about 6.0 to about 8.0 and a metal ion or salt form thereof. The colorant compositions can be derived from a natural product and provide a stable, blue colorant that can be used in food products.
    Type: Grant
    Filed: June 30, 2016
    Date of Patent: August 25, 2020
    Assignee: MARS, INCORPORATED
    Inventors: Rebecca J. Robbins, Thomas M. Collins, Maria Monica Giusti, Gregory Sigurdson

  • High-purity fractionation of anthocyanins from fruits and vegetables
    Patent number: 8575334
    Abstract: Disclosed is a method for separating anthocyanins depleted in phenolic mixture content from fruits or vegetables feedstock containing anthocyanins and phenolic mixtures. The first step is to contact the feedstock with a cation-exchange resin at low pH for a time period effective for the resin to selectively bind with the anthocyanins. Next, the non-bound phenolic mixture is separated from the resin for recovery. The bound resin is subjected to solvent wash to release the anthocyanins for recovery.
