  • Method for improving stability of anthocyanin
    Patent number: 12167741
    Abstract: The present invention relates to the technical field of food science and engineering, and specifically to a method for improving the stability of anthocyanins. In the method, a starch and an anthocyanin are mixed in an aqueous solution of hydrochloric acid, treated at a certain high hydrostatic pressure condition to enable the starch to be gelatinized and to interact with the anthocyanin, and then stored at a certain temperature, so that interaction between the anthocyanin and the starch is further enhanced to form a complex. The method can improve the stability of anthocyanins, which helps to improve the quality of products and extend the shelf life of products.
