摘要
植酸酶分解玉米原料中的植酸磷,释放出无机磷,促进酵母发育及代谢。实验结果表明,发酵时添加植酸酶,酒精含量平均提高0.8%(v/v),原料出酒率平均提高1.6%,即生产1t酒精可节省140kg玉米,效益非常可观。
Phytase could decompose phosphorus-phytate in corn and give out inorganic phosphorus and advance yeast growing and metabolism. Experimental results suggested that addition of phytase in fermentation could increase alcohol content by 0.8 %(v/v) and output rate of raw materials by 1.6 %, namely, 140 kg corn saved for alcohol production per ton.
