摘要
本实验以葵花脱脂粕为原料,通过生物酶法和化学法研究葵花脱脂粕中膳食纤维的提取工艺,其中生物酶法得到的膳食纤维得率较高。生物酶法主要用植物精提复合酶和酸性蛋白酶,提取的最佳工艺组合为:植物精提复合酶的用量为0.4%,植物精提复合酶的酶解时间为2.5h;酸性蛋白酶的用量为0.2%,酸性蛋白酶的酶解时间为45min,此时膳食纤维的得率为78.3%。
In this research, sunflower meal was used as raw material, and dietary fiber of sunflower meal were extracted by enzymatic method and chemical method. The enzymatic method got a higher yield than the chemical method. Plant extraction complex enzymes and acidic protease were used in enzymatic method. The results showed that the optimal extracting condition： plant extraction complex enzymes addition dosage 0.4% for 2.5 hours and acidic protease addition dosage 0.2% for 45 rain. On these conditions extraction ratio of dietary fiber is 78.3%.
