摘要
目的研究利用玉米生产红曲色素的新技术，探讨红曲色素的最佳提取工艺。方法以红曲霉为菌种，种子液体培养发酵、红曲固体发酵生产红曲色素。结果选育优势变异菌种M-04株，红曲固体发酵最佳条件是接种量6％，玉米初始水分35％，发酵温度28～32℃。最佳浸取工艺为：溶剂为70％乙醇水溶液，提取温度60℃，提取时间2h。结论得出了玉米中红曲色素生产的最佳外界条件。
Objectlve To study the new technology of producing the Monascus pigments in corn and the optimal condition of extraction process of the Monascus pigments. Methods The Monascus pigments were produced by fermentation of Monascus seed liquid and Monascus solid fermentation of com. Results A kind of superior species M -04 was obtained and the optimum conditions of Monascus solid fermentation were the load of 6% , the ventilating temperature of 28- 32℃ ,and the corn initial moisture content of 35%. The optimal extraction were extraction agent of 70% alcohol -water , the temperature of 60℃ and the time of 2 h. Conclusion The optimal external factors of producing Monascus pigment have been obtained.
