Process for the preparation of gluconic acid and gluconic acid produced thereby

摘要

An enzymatic system comprised of glucose oxidase and a catalase of the same or different sources to result in the complete conversion of glucose to gluconic acid at a glucose concentration greater than 25% (w/w) ds. The resultant gluconic acid, which is essentially free from impurities normally associated with the fermentation process, is then spray granulated to produce a low-dust dry product.
