Abstract:
The optimum conditions for the extraction of soluble dietary fiber (SDF) by cellulose were explored by using tremella scraps.The antioxidant activity of SDF in different extraction methods were compared.The results showed that the cellulase addition amount was 15 mg?g-1,the enzymolysis time was 3.5 h,the particle size was 120 mesh and the solid-liquid ratio was 1∶70 g?mL-1.Under this condition the extraction rate of SDF was the highest,reaching 36.7%.The ?OH,DPPH?,H2O2 scavenging rate and reducing ability of SDF were 56%,28%,36% and 86.3%,respectively,which were similar to water extraction,and were better than acid and alkaline extraction.
