Abstract

A process for preparing the edible red pigment from the fresh red-core radish includes such steps as washing, slitting, leaching, extracting, macroreticular resin column adsorbing, concentrating, spray drying, vacuum mixing and drying, and deodoring. Its advantages are rich in fish pelargonium pigment glycoside and anthocyanidin glycoside, no radish odor, and high chromatic level greater than 60.

Description

1. Technical field [0001] The invention relates to a method for extracting red pigment from natural red radish, which belongs to the field of deep processing of agricultural products. 2. Background technology [0002] Natural pigments are safe, non-toxic, and colorful, and are loved by people, especially for the coloring of edible products and the huge economic benefits of export earnings, which are of great concern to governments and entrepreneurs in various countries.
