Production methods and others: |
Starch milk is hydrolyzed with sulfuric acid to obtain glucose solution (saccharification solution), and lime milk, nutrient salts and black mold seed nutrient solution are added for fermentation. The fermentation broth is neutralized by adding lime milk, filtered, and the filtrate is concentrated under reduced pressure and crystallized to obtain a crude product, which is refined to obtain calcium gluconate. |
