【摘要】 以花生壳为原料,采用碱液浸提法制备花生壳膳食纤维。结果表明:提取花生壳膳食纤维的最佳工艺条件是1mol／L NaOH溶液,温度40℃,反应时间4．0h。花生壳膳食纤维的最佳脱色工艺条件为 pH=12,6％H2O2溶液,温度40℃,反应时间6．0h。成品气味淡,色泽呈淡黄色,其膨胀力高达5．73mL／g, 持水力为615．86％。更多还原

【Abstract】 The technology of extracting dietary fiber from peanut shell was studied by alkali solution. Results showed that the optimum conditions of the peanut shell dietary fiber extraction were as follows: Imol/L sodium hydroxide, 40℃, 4.0h. And the optimum conditions of decolourling were as follows: pH = 12, 6%H2O2, 40℃, 6.0h.The products smell well and the colour was slightly yellow.Its expansive capacity was 5.73mL/ g and water holding capacity was 615.86 % .更多还原
