Claims (4)
류우신, 이소류우신 및 발린과의 아미노산류 용액을 pH1.5내지 2.0에서 농축시켜 이소류우신과 발린의 함량이 풍부한 제1모액과 류우신 함량이 풍부한 제1과상을 얻은 다음, 모액과 고상을 분리시킴을 특징으로 하는 류우신, 이소류우신 및 발린의 분리방법.The amino acid solution of leucine, isoleucine and valine was concentrated at pH 1.5 to 2.0 to obtain the first mother liquor rich in isoleucine and valine and the first confectionery rich in leucine and then the mother liquor and solid phase. Separation method of leucine, isoleucine and valine characterized by the separation.이소류우신과 발린의 함량이 풍부한 모액에 염산을 첨가하고 모액을 농축시켜 발린과 류우신의 함량이 풍부한 제2모액과 이소류우신의 함량이 풍부한 제2고상을 얻은 다음, 제2모액과 제2고상과를 분리시킴을 특징으로 하는 특허청구의 범위 제1항 기재의 방법.Hydrochloric acid was added to the mother liquor rich in isoleucine and valine, and the mother liquor was concentrated to obtain a second mother liquor rich in valine and leucine and a second solid rich in isoleucine. Method according to claim 1 characterized in that it separates.염산을 첨가하기 전에 모액을 2회 이상 농축시키고 농축조작후마다 고상을 분리시킴을 특징으로 하는 특허청구의 범위 제2항기재의 방법.The method of claim 2, wherein the mother liquor is concentrated two or more times before adding hydrochloric acid and the solid phase is separated after every concentration operation.염산을 첨가하여 생성되는 아미노산 염산염을 약염기성이온 교환체로 처리하여 유리되는 유리아미노산류를 회수함을 특징으로 하는 특허청구의 범위 제2항 또는 제3항의 기재의 방법.The method according to claim 2 or 3, wherein the amino acid hydrochloride produced by adding hydrochloric acid is treated with a weakly basic ion exchanger to recover free free amino acids.* 참고사항 : 최초출원 내용에 의하여 공개하는 것임.* Note: The disclosure is based on the original application.
