【摘要】 |
|
Soluble dietary fiber (SDF) is an extract from spent residue of Cornus officinalis Sieb. et Zucc fruit by ultrasonic. The conditions of the experiment optimized with response surface methodology were ambient temperature of 70.3°C, the ratio of solvent to solid being 30？mL/g, and processing time of 110？min under the ultrasonic wave frequency of 40？kHz and ultrasonic power of 250？W. The best aggregative indicator, incorporating the yield of Cornus SDF (CSDF), the content of SDF, and light transmittance (%, at 620？nm) of SDF, was predicted to be 12.7845 according to the fitting equation. After UV sterilization, 0.25% (w/v) dispersion of CSDF in mineral water presented a good light transmittance (94.9%) and shelf-life (over 2 months). It had no smell and tasted good. The left residue was extracted with caustic soda to get hemicellulose. |
