Ornithine production technology

Abstract

The invention discloses an ornithine production technology. The ornithine production technology is characterized by comprising the following steps: step one. filtering a ornithine fermentation liquid by using a ceramic membrane so as to obtain microfiltration dialysate; step two. carrying out nanofiltration decolorization on the microfiltration dialysate, and further purifying the microfiltration dialysate so as to obtain nanofiltration dialysate; step three. carrying out continuous ion exchange adsorption-desorption on the nanofiltration dialysate by filled hydrogen cation exchange resin so as to obtain ornithined liquor; and step four. concentrating, crystallizing and centrifugally separating the continuous ion exchange adsorption-desorption ornithined liquor, and drying a finished product so as to obtain a ornithine crystal. The ornithine production technology disclosed by the invention has the beneficial effects that the yield is high, the purification effect is good, the product concentration is stable, and the production cost is low.

Description

technical field [0001] The invention relates to the field of amino acid production, in particular to a production process of ornithine. Background technique [0002] The scientific name of Ornithine is α, δ-diaminovaleric acid, its molecular formula is C5H12N2O2, and its relative molecular mass is 132.16. It is an essential intermediate metabolite in human metabolism, mainly participates in the ornithine cycle (uric acid cycle, Krebs-Henseleit cycle), and plays an important role in the discharge of ammonia nitrogen. Its multifunctional health care function has made the development of ornithine products gradually heated up in recent years, and its application in the fields of medicine, health care and chemical industry is also becoming more and more extensive. [0003] The current production method of ornithine mainly includes the following steps: filtration, adsorption and analysis, ammonia removal, concentrated crystallization, centrifugal separation, and drying of the fin...

AI Technical Summary

Problems solved by technology

The ammonium-type strongly acidic ion-exchange resin used in the method has a relatively low adsorption capacity for ornithine, resulting in a low concentration of the desorbed product, and the ammonium-type resin is not firmly adsorbed, resulting in a low yield.
