Perilla pigment is a water-soluble pigment. The main ingredients are perilla element and purpurin, which are anthocyanin pigments. Anthocyanin substances are widely present in various plants. The adsorption purification method is a production process in which a macroporous adsorption resin is used to adsorb a pigment in an extract, and then the pigment is eluted with a suitable eluent to purify the purified pigment.

The macroporous adsorbent resin (special resin for extracting perilla pigment) provided by Suzhou Bojie Resin Technology Co., Ltd. can effectively enrich perilla pigment, has large adsorption capacity and fast adsorption rate, and the obtained perilla pigment product has high purity and dissolution. It has good characteristics and small color change, and has been widely used in the production of perilla pigment. The resin has high mechanical strength, wear resistance, easy desorption and regeneration, and good economic benefits.
