| 摘 要： | 对紫红薯渣、膳食纤维和漂白膳食纤维的物化特性进行了测试与分析。结果表明,紫红薯膳食纤维的水合性质与紫红薯渣相比差异极显著(P<0.01),H2O2处理极显著地降低了紫红薯膳食纤维的水合性质;酶法和H2O2处理降低了样品吸附胆酸钠的能力,但提高了吸附亚硝酸钠的能力;紫红薯渣、膳食纤维和漂白膳食纤维的水合性质分别为:膨胀力4.36、14.3、9.30 mL/g,持水力2.65、8.39、6.49 g/g,结合水力1.89、3.12、2.05 g/g;紫红薯渣、膳食纤维和漂白膳食纤维的阳离子交换能力分别为0.12、0.88、0.48 mmol/g;紫红薯渣、膳食纤维和漂白膳食纤维吸附胆酸钠的能力分别为35.03、24.12、17.84 mg/g;紫红薯渣、膳食纤维和漂白膳食纤维吸附NaNO2的能力分别为1.08、2.81、2.98 mg/g。结果显示,紫红薯膳食纤维是一种天然的优质膳食纤维,具有广阔的应用前景。

| Abstract: | The physicochemical properties of the dregs,the dietary fiber and the bleached dietary fiber from purple sweet potato were measured and compared.Results:There are remarkable differences in the hydration properties(P<0.01)between the dietary fiber and dregs from purple sweet potato;The hydration properties are weakened markedly after bleaching by hydrogen peroxide.In vitro,the adsorption capacity of the dietary fiber for sodium nitrite increases,but for sodium cholate decreases after treatment with H2O2 or e... |
