Abstract:

The fermentation processing for fiber degradation from the residue of oil-tea-cake after the extraction of tea saponin was investigated. According to results of single-factor experiments, soybean residue, rice bran, water content and fermentation time were selected for the Box-Behnken design to establish a quadric regression equation for describing the degradation of fiber. The optimal fermentation conditions were achieved by response surface analysis to be soybean residue of 29.38%, rice bran of 18.54%, water content of 72% and fermentation time of 74.9 h. Under the optimal fermentation conditions, the highest degradation of fiber reached up to 48.65%, which was consistent with 48.36% of the validated value.

Key words: Neurospora. crassa, oil-tea-cake, fermentation processing, response surface methodology
