【摘要】 以黑米为原料生产黑米黄酒,黑米色素提取以浓度为20％-30％(v/v)的乙醇或米酒为最佳萃取溶剂,分两次萃取;黑米色素溶液及加工的黑米酒系列产品在酸性条件下色泽较稳定, 适量使用蔗糖、柠檬酸或抗坏血酸等护色剂可明显提高产品色泽的稳定性;加工黑米黄酒,黑米原料仅需15％-20％,其余可用白糯米代替。更多还原

【Abstract】 Black rice was used as raw materials to produce yellow rice wine. 20 %-30 %(v/v) ethanol or rice wine was the best extraction solvent for black rice colority extraction and the extraction operated twice. Black rice colority solution and the processed wine had stable color under acid conditions. Accordingly, adequate use of color fixatives such as sugar cane, citric acid and ascorbic acid etc. could evidently improve the stability of product color. Only 15 %-20 % black rice was required during the production and other part could be placed by white glutinous rice.更多还原
