功能性红曲色素发酵工艺研究

本文研究了以早籼米为原料,以红曲霉为菌种,种子液体发酵、红曲固体发酵生产红曲色素新工艺。选育优势菌株SM005h一株,种子液体发酵最佳条件是6%接种量,1:0.5通气量,搅拌转速350r/min,31℃下培养31h。红曲固体发酵最佳条件是接种量6%,米饭初始水分38%,发酵温度32～35℃。

It has been developed that the new technology of producing functional Monascus pigments by fermentation of seedMonascus liquid and solid fermentation of red kojic rice.Using indica rice as material, a kind of superior species SM005h wasobtained.The optimum conditions of seed liquid fermentation were 6% load, 1:0.5 ventilating ratio, 350r/min stirring,31℃temperature and 31h cultivating.The optimum conditions of red kojic solid fermentation were 6% load, 32～35℃ ventilatingtemperature and 38% rice initial moisture content.
