| 摘 要： | 以火棘果为原料，采用碱水解法提取膳食纤维，通过单因素试验和响应面分析，探讨碱液质量分数、浸提时间、浸提温度和液料比对火棘水不溶性膳食纤维提取率和纯度的影响，并对提取工艺条件进行优化。结果表明，碱水解法提取火棘膳食纤维的最佳工艺条件为碱液质量分数1.00%、浸提时间3.00h、浸提温度77.8℃、液料比17:1(mL/g)，在此工艺条件下水不溶性膳食纤维的提取率56.89%、纯度达到92.74%，表明该工艺可行。

| Abstract: | The alkali-catalyzed hydrolysis method was applied to extract insoluble dietary fiber(IDF) from the fruits of Fortuneana pyracantha and main process conditions were optimized by one-factor-at-at-a-time experiments and response surface methodology.The extraction rate and purity of IDF were investigated with respect to NaOH concentration,extraction time,extraction temperature and material-to-liquid ratio.The results showed that the optimal extraction conditions were NaOH concentration of 1.00%(g/g),extraction... |
