摘　　要：桔霉素问题已成为困扰红曲色素进一步推广的重要问题,使红曲类产品的深度开发和利用受到限制,限制了我国红曲产品的出口。本文主要探讨桔霉素的后处理脱除方法,并用薄层色谱法测定处理前后的红曲色素组分变化。结果表明,利用相当于红曲色素重量11％的NaOH溶解醇溶性红曲色素,在沸水浴中加热处理,可以在短时间内消除桔霉素。The Monascus colorant industry had been worried at the citrinin.The citrini limited the exploitation,and application,and export of Monascus products.The detoxication by alkali process,and the changes of Monascus colorant compositions before and after process by thin-chromatography were investigated.It was showed,that the citrinin was detoxicated within NaOH in 11% weight of Monascus colorant at hot water bath in a short time.
