- 摘要:
- 以胡萝卜渣为原料,采用二次回归正交旋转试验方法对提取液体积、氢氧化钠质量分数、提取时间和提取温度4个单因素工艺参数进行了研究,以优化胡萝卜渣不溶性膳食纤维提取工艺。结果表明:回归得到二次多项式模型极显著,模型的相关系数为0.9326,用响应面分析法确定4个因素的最佳工艺条件为提取液体积15 mL/g、氢氧化钠质量分数11%、提取时间5 h和提取温度38℃,不溶性膳食纤维得率为49.01%。其物化性能的试验结果表明,不溶性膳食纤维的膨胀力和持水力分别为8.87 mL/g和3.97 g/g。
- Abstract:
- Taking carrot pomace as material,the volume of extract,alkali concentration,extracting time and extracting temperature were studied by using quadratic rotary combinational design,in order to optimize the extraction of insoluble dietary fiber (IDF) from carrot pomace.The results showed quadratic model was the best model to describe the relationship between the yield of IDF and the factors.R-squared adjusted value of the model was 0.9326.The optimized conditions for IDF extraction were 11% of alkali concentration at the amount of extract of 15 mL,extracting time of 5 h and extracting temperature of 38℃.The yield of IDF was 49.01%.The results of physical and chemical properties showed that the swelling capacity was 8.87 mL/g and water holding capacity was 3.97 g/g.
