| titleOfInvention | Clean production method of yam diosgenin |
| abstract | The invention aims at providing a clean production method of yam diosgenin. The clean production method of yam diosgenin is high-efficiency and environmentallyenvironment-friendly and can be used for extracting diosgenin without needing acid hydrolysis and meanwhile realizing the separation of fibers and starch in diosgenin. The clean production method comprises the following steps: firstly separating starch, fibrous residues and dioscin in yam, then intercepting dioscin through nanofiltration, and biologically converting 70-80% of dioscin into the diosgenin by using lactobacillus acidophilus biotransformation, and wherein recycling the unconverted diosgenin can be subjected to through nanofiltration again and can be recycled and reused for biotransformation in the next production process. The clean production method has the advantages that the acid hydrolysis is avoided in the whole diosgenin extraction process, the wastewater treatment is simple, the residues obtained after suction filtration can be used as fertilizer, and the clean production method has low pollution on the whole and is clean, safe and environmentallyenvironment-friendly; and meanwhile, the conversion rate of the diosgenin in the yam is substantially increased, the starch is separated from the fibrous residues, and the problem of excessive BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) in wastewater is also avoided by separating the starch from the fibrous residues. |
