Abstract
The comprehensive steriod plant processing process includes pressurizing, sandwich heating and hydrolysis inside one sealed pressure reactor with sulfuric acid as catalyst. The said process has no damage to saponin while converting recovering all effective components in steroid plant. The solution after separating hydrolysate can be converted into biochemical product via microbe conversion, and the mother liquor after recovery can be reused in the pressurizing hydrolysis. The production process is closed and circulated and has short production process and no exhaust of waste water, slag and waste gas; and can be used in industrial production.
Description
Technical field: the present invention relates to a kind of working method that fully utilizes the steroidal plant.
Background technology: the operational path that traditional production technique of extraction saponin is taked from steroidal plant roots and stems such as yellow ginger, valley dragon, duration and degree of heating root, Dioscorea panthaica Prain et Burkill is: fermentation method, hydrochloric acid hydrolysis method, fermentation---hydrochloric acid hydrolysis method.The common feature of above-mentioned production technique is: the production cycle is long, and fermentation needs 7-15 days; The wasting of resources is big, and the remaining vegetable composition all discharges except that saponin, and serious environment pollution is produced the waste water that acid contains plant body residual substance that contains that one ton of saponin will be discharged kiloton, the severe contamination river water quality.The processing method of other trials has simple hydrochloric acid hydrolysis method, and the shortcoming of this method is: hydrogen ion is crossed the structure of destroying saponin at most, and it is incomplete that hydrogen ion is crossed hydrolysis at least.Simple fermentation then easily produces secondary saponin and influences extraction yield, is difficult to realize suitability for industrialized production.
Summary of the invention: the present invention is in order to solve the problem that the production cycle is long, the wasting of resources is big, environmental pollution is serious in traditional working method of utilizing effective constituents such as steroidal plant extract saponin, a kind of working method that fully utilizes the steroidal plant has been proposed, it is characterized in that: described method is in the closed pressure reaction still, with sulfuric acid is catalyzer, pressurization, chuck heating hydrolysis.Adopt this method, neither destroy the structure of saponin, make again that each active principle all transforms recovery in the steroidal plant; Solution behind the separation hydrolyzate can become biochemical product through microbial transformation, mother liquor after the recovery can be used for pressurized hydrolysis once more, and whole process of production is closed cycle, no waste water, waste residue, exhaust gas discharging, and with short production cycle, can realize the production of industrialization streamline.
Embodiment: be placed in the closed pressure reaction still after by present method steroidal plant rhizome such as yellow ginger, Dioscorea nipponica Mak. Ningpo Yam Rhizome, Dioscorea panthaica Prain et Burkill, duration and degree of heating root being pulverized, add sulfuric acid catalyst, pressurization, chuck heating hydrolysis after-filtration, wherein filter residue extracts saponin after washing, drying, and the residue after it extracts promptly is a fertilizer; Isolate reduction liquid glucose and vitriol with after-filtration during filtrate is carried out, the liquid glucose that wherein reduces carries out microbial transformation, generates other biochemical products.Because in specific pressure and temperature scope, carry out forced hydrolysis with sulfuric acid as catalyzer, neither destroy the structure of saponin, make again that each active principle is separated from each other in the steroidal plant, all transform, can reclaim respectively.Separate the acidic solution of forming by reducing sugar and sulfuric acid behind the hydrolyzate, separablely after neutralizing go out vitriol, reducing sugar is become biochemical products such as alcohol, citric acid by microbial transformation, mother liquor after the recovery can be used for pressurized hydrolysis once more, water of productive use is closed cycle in whole process of production, no waste water, waste residue, exhaust gas discharging.Especially with short production cycle, hydrolysis reaction is a few hours only.
Adopt this method result of implementation as follows:
Lab scale: hydrolysis cadmium yellow ginger 1000 grams, get hydrolyzate 57 grams, extract saponin 7.2 grams, the rate of recovery 7.2 ‰; The reduction sugar concentration is 15%;
Pilot scale: 800 kilograms of hydrolysis cadmium yellow ginger, get 60 kilograms of hydrolyzates, saponin extraction yield 7.2 ‰, concentration of reduced sugar are 18.25%.
