摘要
为提高白酒中愈创木酚类物质浓度,将一株产愈创木酚的YF-58产氮假单胞菌用于制备细菌麸曲。以愈创木酚浓度为指标,固定培养温度为30℃,通过单因素试验确定细菌麸曲的最佳水分含量、接种量和培养时间,并将所得细菌麸曲按照不同添加比例进行实验室条件下酱香型白酒酿造试验。结果表明,细菌麸曲的最佳培养条件为水分含量40%、接种量7%、培养温度30℃、培养时间3 d,酿酒用曲最佳添加比例是高温大曲:细菌麸曲为3:2,此条件下所酿造白酒的出酒率、愈创木酚浓度和4-乙基愈创木酚浓度较对照组分别提高了39%、223%、130%。该研究可为后续提高白酒中愈创木酚浓度提供一定的理论依据。
In order to increase the content of guaiacol in Chinese Baijiu,a strain of Pseudomonas YF-58 with high guaiacol-producing capacity was used to prepare bacterial Fuqu.With the concentration of guaiacol as the index,the optimum water content,inoculation amount and culture time of bacterial Fuqu were determined at 30℃.The obtained bacterial Fuqu was tested for solid-state brewing experiments of Moutai-flavored Baijiu according to different addition amounts.The results showed that the optimal conditions for the bacterium Fuqu were 40%moisture,7%inoculation amount,30℃incubation temperature,3 days of incubation time,and the optimal ratio of Fuqu for sake brewing is 3:2 for high-temperature Daqu:bacterial Fuqu.Under these conditions,the yield,guaiacol concentration and 4-ethyl guaiacol concentration of Baijiu were increased by 39%,223%and 130%,respectively.This study provides a theoretical basis for increasing the concentration of guaiacol in Baijiu.
