摘　　要：为提高麸曲白酒的品质,明确白酒酿造过程中所用麸曲糖化菌种的种类及用量,获得酒体干净、风味独特、发酵周期短的多微麸曲清香型白酒,以液化力、糖化力为指标,通过单因素实验研究了以米根霉、米曲霉1号、米曲霉2号、红曲霉、紫红曲霉为糖化菌种按不同接种量制备米曲,对米曲液化力、糖化力的作用进行分析,并进行四因素三水平的正交实验获得最优的菌种配比。结果表明,米根霉3%,在此基础上米曲霉1号4%、红曲霉3%的配比制备的米曲,其液化力和糖化力可得到显著提高。For improving the quality of bran starter liquor,clarifying the type and dosage of saccharifying strains used in liquor brewing,and obtaining multiple-microbe bran starter liquor with clean body,unique flavor and short fermentation period,liquefaction power and saccharification power were used as indexes in this experiment,the effects of different inoculum size of Rhizopus oryzae,Aspergillus oryzae No.1,Aspergillus oryzae No.2,Monascus and Monascus purpureus as saccharifying strains on liquefaction power and saccharification power of rice-koji were studied by single factor experiment.According to this result,an orthogonal experiment with four factors and three levels was carried out to optimize the proportion of strains.The results showed that the quality of rice-koji was obviously improved by adding Rhizopus oryzae 3%,Aspergillus oryzae No.14%and Monascus 3%.
