Lactic acid decolorizing resin

Lactic acid decolorizing resin
Lactic acid is widely used in the food and pharmaceutical industries. Currently mainly produced by fermentation. The Lactobacillus fermentation broth is neutralized by calcium oxide, filtered, evaporated, crystallized, acidified, etc. to obtain a lactic acid intermediate product having a content of about 25%. After further decolorization, evaporation and concentration gave the finished lactic acid. The finished grade lactic acid should be a colorless or yellowish syrupy liquid, and the decolorization process is especially important in the lactic acid production process.
The macroporous adsorbent resin (specific resin for decolorization of lactic acid) provided by Suzhou Bojie Resin Technology Co., Ltd. has remarkable decolorization effect, decolorization of lactic acid in the exchange column, large amount of lactic acid treated by single batch of resin, high decolorization rate, convenient regeneration, and many times Repeated use, low difficulty in operation, high mechanical strength, abrasion resistance, acid and alkali resistance, suitable for industrial large-scale production.
