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%。

Abstract: 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 min. On these conditions extraction ratio of dietary fiber is 78.3%.
