Method for the production of granular citric acid and salts thereof

摘要

Disclosed is an improved method for preparing a particulate citric acid or an alkali metal or alkaline earth metal salt thereof. The method involves spray granulating citric acid or a salt thereof from its partially purified fermentation broth to form granules which are freer flowing and less inclined to fracture than is citric acid or its salts prepared by crystallization techniques which properties render the material prepared by the present method suitable for handling in bulk.
