| 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pH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 mPa·s，产品质量较优。

| Abstract: | Using lemon peel pomace as raw materials, dietary fiber was prepared by enzymatic hydrolysis method. The soluble dietary fiber (SDF)/ insoluble dietary fiber (IDF) ratio and the physicochemical properties were evaluated with different enzyme addition, enzymatic hydrolysis time, enzyme solution temperature and pH. The results showed that the lemon dietary fiber would have appropriate SDF/IDF ratio (0.67), high total flavonoid content (4.82 mg/100 g) and VC content (247 mg/100 g), good whiteness L* (90.23) and high viscosity (7.57 mPa·s), when the lemon pomace was extracted with enzyme 1%, temperature 60 ℃, time 12 min and pH 6. |
