Abstract

The invention relates to a post-extraction process for preparing low acyl gellan gum having high solubility property, the process comprising the following steps: (1) enzyme treatment of fermentation broth; (2) flocculation of fermentation broth; (3) deacylation treatment; (4) clarification treatment of deacylated solution; (5) dehydration treatment of clarified and deacylated gellan gum solution; (6) ion exchange and decoloration treatment; and (7) drying and milling. The process according to the invention produces a product, which has largely improved solubility, largely improved quality, good appearance, high transparence, and high gel strength.
