Problems solved by technology

At present, the production of biodiesel from animal and vegetable oils faces problems such as high cost, a large gap in the total amount of raw materials, and strong seasonal supply, which are not conducive to large-scale production.
Moreover, continuing to expand the cultivation of traditional oil crops to obtain raw materials for biodiesel production will have problems such as competition with others for food and land

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with specific embodiments.

[0028] The extraction method of chrysanthemum leaf diosgenin in this example comprises the following steps:

[0029] 1) Slurry process of Dioscorea chrysanthemum paste: Wash the raw materials of Dioscorea chrysanthemum leaves, dry them in the air, crush them and sieve them to obtain fine powder, stir the powder with warm water at 40-60°C in a weight ratio of 1:3-8 pulp;

[0030] 2) Dioscorea chrysanthemum paste saccharification process: Add α-amylase to the slurry obtained in step 1), the weight ratio of α-amylase to Dioscorea chrysanthemum is 10-40 μ: 1, and adjust the pH value to 5.0-- -7.0, heat to 90-100°C and keep warm for liquefaction for 30-80min, then cool to 55-65°C, add cellulase and glucoamylase, the weight ratio of cellulase to Dioscorea chrysanthemi is 100-120μ:1, and saccharify The weight ratio of the enzyme to Dioscorea chrysanthemum is 100-200 μ:...

Abstract

The invention provides an extraction method of dioscorea composita saponin. The extraction method comprises the following steps of (1) a dioscorea composita slurrying process; (2) a dioscorea composita slurry saccharifying process; (3) a separation process; (4) a hydrolytic process; (5) a fermentation process; (6) a dioscorea composita saponin extraction process. The extraction method of the finished saponin can not only sufficiently utilize the effective components contained in dioscorea composita and greatly enhance the transformation rate of the dioscorea composita saponin, but also reduce the discharge and treatment of wastes by using residues obtained after suction filtration as a fertilizer, and is less in integral pollution, thereby being more favorable to environmental-friendly and cleaning safety.

Description

technical field [0001] The invention belongs to the field of diosgenin production, and in particular relates to a method for extracting diosgenin from chrysanthemum leaves. Background technique [0002] In order to solve the increasingly serious problems of energy shortage and environmental degradation, countries around the world are vigorously developing renewable liquid fuels, among which biodiesel is the most potential bioenergy product. At present, the production of biodiesel from animal and vegetable oils faces difficulties such as high cost, a large gap in the total amount of raw materials, and strong seasonal supply, which are not conducive to large-scale production. Moreover, continuing to expand the cultivation of traditional oil crops to obtain raw materials for biodiesel production will have problems such as competition with people for food and land with food. Therefore, developing new oil resources is the key to reducing the price of biodiesel and ensuring the s...
