Microencapsulation by lyophilization of carotenoids produced by Phaffia rhodozyma with soy protein as the encapsulating agent
Abstract Carotenoids are pigments that can be applied to food but they are unstable towards certain food intrinsic conditions, as well as processing ones. Microencapsulation is an alternative to increasing their stability. This study aimed to produce carotenoids by Phaffia rhodozyma crops and promot...
