Title:
L-ORNITHINE COMPOSITE SALT AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/104432
Kind Code:
A1
Abstract:
Provided is a preparation method for an L-ornithine composite salt. The preparation method comprises the following steps: (1) taking an L-ornithine salt solution as a raw material to prepare a free L-ornithine solution by means of a bipolar membrane electrodialysis apparatus; (2) enabling the free L-ornithine solution and substance A to be mixed and reacted to obtain an L-ornithine composite salt solution, the substance A being L-Aspartic acid, α-ketoglutaric acid, or R-(+)-lipoic acid; (3) enabling the L-ornithine composite salt solution to be crystallized to obtain the L-ornithine composite salt. The L-ornithine composite salt prepared by using the preparation method has a water content of less than 2%, no by-product generation, and no waste salt, waste water and other pollution, is green and environmentally friendly, and has an appreciable yield.
