摘　　要：选取新鲜甜玉米为原料,经预筛、打浆、调配、均质、杀菌等工艺制得甜玉米饮料。确定甜玉米打浆最佳料液比为1∶5 g/mL,并研究了蔗糖、柠檬酸、NaCl添加量对甜玉米汁感官评价的影响。选用了四种不同的亲水胶体研究其对甜玉米饮料稳定性的影响,在单因素试验的基础上,设计正交试验,进一步优化甜玉米饮料调配工艺。试验结果表明:蔗糖添加量4%、柠檬酸添加量0.1%、NaCl添加量0.15%时制得的甜玉米饮料感官评价最好,呈黄色,酸甜爽口,饱满柔和。加入魔芋胶0.01%、CMC0.06%、海藻酸钠0.06%作为甜玉米汁饮料的复配稳定剂,制得甜玉米饮料稳定性最佳。Sweet corn beverage was prepared from fresh sweet corn by pre-sieving,beating,blending,homogenization and sterilization.The best ratio of sweet corn to beating to water is determined to be 1∶5 g/mL,sucrose,citric acid and NaCl on the sensory evaluation of sweet corn juice were studied,and four different hydrophilic colloid were selected to study their effects on the stability of sweet corn drinks.Based on the single-factor experiment,orthogonal experiment was designed to further optimize the sweet corn drink blending technology.According to the experimental results,the sweet corn beverage made with 4%sucrose,0.1%citric acid and 0.15%NaCl had the best sensory evaluation,with yellow,sweet and sour taste,plump and soft.The stability of sweet corn drink was best when konjac gum 0.01%,CMC 0.06%and sodium alginate 0.06%were added as the compound stabilizer of sweet corn drink.
