Process for producing low-citrinin monascus red

The invention relates to a process for producing low-citrinin monascus red. The process comprises the following steps: inoculating a monascus bacterium into a long-shaped rice culture medium, performing rice bacterium culture so as to obtain monascus rice, drying, crushing, performing alcohol extraction, filtering so as to obtain a monascus red liquid, and finally performing oxidation and radiation or radiation and oxidation in sequence, so as to obtain a finished product, wherein the radiation dosage is 7-8kGy. The invention aims to provide the process for producing low-citrinin monascus red. 本发明涉及种低桔霉素红曲红的生产工艺，将红曲霉菌体接种入籼米培养基中进行米粒菌种培养以获得红曲米，然后进行干燥、粉碎、醇提、过滤后得到红曲红液体，最后先氧化再辐照或者先辐照再氧化，而得成品；所述辐照剂量为7kGy-8kGy。本发明的目的在于提供种低桔霉素红曲红的生产工艺。
