Process for organic acid extraction from fermentation liquid using membrane method

Abstract

The invention discloses a process for extracting organic acid from fermentation liquor through film method, which consists of the steps of fermentation liquor preparation, ultrafiltration, nano filtration, deionization and concentration. The invention has the advantages of simple operational process, low cost of production, high yield, and complete de-sugaring.

Description

Technical field: [0001] The invention relates to a process for extracting organic acid from fermented liquid, in particular to a process for extracting organic acid from fermented liquid by membrane method. Background technique: [0002] Obtaining organic acids by fermentation is one of the important topics in bioengineering research, but organic acids mostly exist in the form of salt in the fermentation broth, the acid production rate is low, and extraction is difficult. At present, although there are many methods for extracting organic acids from fermentation broth, they cannot be widely promoted due to low yield, high cost, environmental protection, safety and other factors. Invention content: [0003] The purpose of the present invention is to provide a process of extracting organic acids from fermentation broth with simple operation process, easy implementation of industrial production, low production cost and high yield, especially a process of extracting organic aci...
