Abstract

Water-Soluble Dietary Fiber(SDF) extraction flow was studied combining methods of alkali solution and alcohol precipitation by use of corn spermoderm as raw materials.The results showed that the optimal extraction process as follows,the extraction time of alkali solution was 30 min,the temperature of alkali solution was 50 ℃,the mass fraction of sodium hydroxide was 1 %,the ratio of material to alcohol was 1∶2(g/mL),the time of alcohol precipitation was 30 min;the temperature of alcohol precipitation was 40 ℃.
