摘  要：
[目的]寻求黑玉米饮料的最佳生产工艺。[方法]以成熟度为60%~70%的黑玉米鲜穗为材料生产黑玉米饮料,研究不同酶解条件、糖化时间、糖化酶用量和稳定剂等对产品质量的影响。[结果]最佳酶解条件为:a-2淀粉酶用量1%,90℃保温酶解5 min;糖化酶参考用量为:液化DE值17%,淀粉乳33%,酶制剂240 U/g淀粉,实际生产中,糖化酶加入比例1%,55~60℃保温糖化4~5 h;添加比例为0.20%的复合稳定剂(琼脂+黄原胶)的稳定效果最好;三聚磷酸钠、食盐、柠檬酸钠等对饮料电解质平衡和稳定性具有重要影响。[结论]黑玉米饮料的最佳生产工艺为:a-2淀粉酶(添加比例1%)90℃酶解5 min,糖化酶(添加比例1%)55~60℃糖化4~5 h,0.20%复合稳定剂(琼脂+黄原胶)。

摘  要：
[Objective] The aim was to seek the optimal production process of black corn beverage.[Method] Black corn beverage was produced with material of fresh black corn which maturity was 60%-70%.The effects of different enzymatic hydrolysis conditions,saccharifying time,saccharidase dosage and stabilizer on the quality of products were investigated.[Result] The optimal enzymatic hydrolysis conditions was that α-2 amylase amount of 1% and enxymatic time of 5 min at 90 ℃.The referencing quantity of saccharidase was that liquefied DE value of 17%,starch milk of 33% and enzyme preparation of 240 U/g starch.In actual production,the addition proportion of saccharidase was1%,the saccharifying time was 4-5 h at 55-60 ℃.The stable effect of compound stabilizer(agar +xanthan) at 0.20% was the best.The effects of sodium tripolyphosphate,salt and sodium citrate on electrolyte balance and stability of beverage were important.[Conclusion] The optimal process for producing black corn beverage was that enxymatic time of 5 min at 90 ℃ with 1% α-2 amylase,saccharifying time of 4-5 h at 55-60 ℃ with 1% saccharidase and compound stabilizer(agar +xanthan) of 0.20%.
