Abstract: With pumpkin and mung bean as raw materials,a variety of enzymes as hydrolysis agent,the research was toproduce a kind of compound drink which is not only nutritious ,but also has the unique aroma and flavor of pumpkinand mung bean. The optimum technological parameters which were determined through single factor experiments andorthogonal experiment were as follows:1.The optimum conditions for enzymatic hydrolysis of pumpkin were:cellulose0.4%,pectinase 0.05%,enzymatic hydrolysis pH 4.5,enzymatic hydrolysis temperature 50℃ ,enzymatic hydrolysistime 2.0h.2.The optimum conditions for enzymatic hydrolysis of mung bean starch were: Alpha amylase0.2% ,enzymatic hydrolysis pH 6.0,enzymatic hydrolysis temperature 60℃ ,enzymatic hydrolysis time 2.0h. 3.The optimumconditions for enzymatic hydrolysis of mung bean protein were: papain0.05%,enzymatic hydrolysis pH 6.5,enzymatichydrolysis temperature 60℃ ,enzymatic hydrolysis time 2.0h. 4.The optimum formula of the compound drink bypumpkin and mung bean were: the proportion of pumpkin juice and mung bean juice 4∶6,white sugar 12%,Citricacid0.1% and salt 0.04%
