摘  要:
以菜籽皮为原料,采用氢氧化钠溶液为溶剂,通过单因素实验和响应面法研究了料液比、氢氧化钠浓度、温度和时间对碱法提取菜籽皮不溶性膳食纤维得率的影响。结果表明当料液比为1:17(g/mL)、氢氧化钠浓度为2.0mol/L、温度为50℃、时间为45min时,菜籽皮不溶性膳食纤维的得率最高,达到65.92%。

摘  要:
Water insoluble dietary fiber extracted from rapeseed hull by alkaline hydrolysis method and by using Sodium hydroxide(NaOH) as solution was studied.Effects of four crucial parameters(the ratio of material to solution,alkali concentration,temperature and time) on extraction yield of water insoluble dietary fiber were investigated trough single-factor experiment method.Subsequently,a central composition experimental design was performed to attain the maximum extraction yield of water insoluble dietary fiber.Under the optimized conditions as follows:the ratio of material to solution 1:17(g/mL),alkali concentration 2.0mol/L,temperature 50℃ and time 45min,the yield of water insoluble dietary fiber was found to be 65.92%.
