Embodiment Construction

[0024] Slightly heat the emulsified L-lactic acid fermentation broth to make it into a suspension, take 1L in a beaker, and then add a certain amount of magnetic polymer (30-50mg chitosan, 80-100μl acetic acid and 90-110mg Fe3O4), stir at normal speed for about 1-2min, until obvious flocs appear; immediately put the magnet on the bottom of the beaker, after 1 minute, you will see that the fermentation broth is separated from the flocs, and remove the supernatant , Measure its OD value and L-lactic acid content.

Abstract

This invention discloses a method for pretreating L-lactic acid fermentation solution with magnetic polymer by flocculation. The magnetic polymer is prepared from chitosan and ferroferric oxide in a weak acid condition. The method comprises: adding the magnetic polymer into L-lactic acid fermentation solution, stirring so that a flox occurs, applying a magnetic field for 1-2 min to separate the floc from the solution, and removing the floc to obtain L-lactic acid fermentation solution. The method has such advantages as simple process, high flocculation rate, compact floc structure, rapid solid-liquid separation, high treating efficiency and no influence on L-lactic acid content in the fermentation solution. The method has potential applications in the pretreatment of L-lactic acid fermentation solution.

Description

technical field [0001] The invention belongs to a pretreatment method of L-lactic acid fermentation liquid. Background technique [0002] Lactic acid is a versatile fine chemical that can be widely used in food, pharmaceuticals, tanning, textiles, environmental protection and agriculture. The main forms of its products are sour agents, flavoring agents, preservatives, tanning agents, plant growth regulators, biodegradable materials and chiral drugs, etc. Some people have predicted that lactic acid will become one of the largest organic chemical products. Lactic acid has three optical isomers, L-, D-, and DL-. Since the human body can only metabolize L-lactic acid, the research and development of L-lactic acid has aroused widespread interest. L-lactic acid is generally produced by the fermentation method of Rhizopus oryzae. In addition to L-calcium lactate, the fermentation liquid also contains bacteria fragments, protein, pigment, residual sugar and other impurities. These...
