With the development of science and technology, the research and development of natural pigments have been promoted due to the continued discovery of the chronic toxicity and carcinogenic effects of many synthetic pigments. Rose Li is rich in resources, and the rose plum red pigment is widely used, pure and natural. The macroporous adsorption resin has the advantages of large adsorption capacity, good adsorption selectivity, simple regeneration, long service life, and cost saving, and has remarkable effects in pigment extraction.
Suzhou Bojie Resin Technology Co., Ltd. provides macroporous adsorbent resin (special resin for rose plum red pigment extraction). The purity of rose plum red pigment is high, the amount of desorbent is small, the desorption process is simple, and elution with ethanol solution is safe. The operation process is simple. The whole process chemical reagent only uses water and ethanol, which will not pollute the environment, is conducive to environmental protection, saves processing cost, and has high mechanical strength and economical utility.
