Abstract

The invention discloses a processing method for a lysine-containing solution. The processing method includes that the lysine-containing solution is enabled to sequentially pass one or more groups of positive ion exchange resin column groups which are in serial connection sequentially until the concentration of lysine in liquid flowed from ends of the one or more groups of positive ion exchange resin column groups is not larger than 0.1g / dL, each group of positive ion exchange resin column groups comprises one or more positive ion exchange resin columns which are in a parallel connection, and positive ion exchange resin columns with lysine are subjected to elution with an alkaline solution to obtain a lysine-containing elution. The processing method for the lysine-containing solution is characterized in that the lysine-containing solution passes the positive ion exchange resin column groups under the condition that the pH is 1.0-2.0 or the concentration of lysine is not lower than 1.0g / dL. The invention further discloses a circulating processing method for the lysine-containing solution. The processing method can improve the yield of the lysine, and be widely applied to industrial production.

Description

technical field [0001] The invention relates to a treatment method for a solution containing lysine. Background technique [0002] Lysine is the eight basic amino acids necessary for the human body (also known as essential amino acids, they are lysine, threonine, leucine, isoleucine, methionine, valine, phenylalanine and tryptophan )one. Lysine has a high solubility in water, and it is easy to absorb carbon dioxide in the air, so it is difficult to obtain its crystallization. Therefore, as a commodity it often appears in the form of monohydrochloride. Lysine has a wide range of uses and is mainly used in the following industries: food industry, preparation of nutritional enhancers, flavoring agents, and sweeteners; feed industry, preparation of nutritional enhancers; pharmaceutical industry, preparation of amino acid infusions, amino acid derivatives, and amino acid salts; Chemical industry, preparation of detergents, skin care products, artificial leather; agriculture, p...
