【摘要】：以柠檬皮渣为原料,使用酶解法制备柠檬膳食纤维。在不同酶制剂用量、酶解时间、酶解温度和p H值条件下制备柠檬膳食纤维,并测定可溶性膳食纤维(SDF)/不溶性膳食纤维(IDF)比值和理化指标。结果表明:柠檬皮渣在1%的酶用量,酶解时间12 min,酶解温度60℃,pH值为6的条件下处理时,得到的柠檬膳食纤维产品SDF/IDF为0.67,总黄酮含量为4.82 mg/100 g,VC含量为247 mg/100 g,白度L*为90.23,黏度为7.57 m Pa·s,产品质量较优。
[Abstract]:Lemon dietary fiber was prepared by enzymatic hydrolysis of lemon peel dregs. Lemon dietary fiber was prepared under different enzyme dosage, hydrolysis time, enzymatic hydrolysis temperature and pH value, and the ratio of soluble dietary fiber SDF and insoluble dietary fiber (IDF) and physicochemical index were measured. The results showed that under the conditions of 1% enzyme dosage, 12 min enzymatic hydrolysis time and 60 鈩，
