Embodiment 1

[0018] Take 300g fresh turmeric and add double water slurry to grind to fine particle size. After natural enzymolysis for 50 hours, adjust sulfuric acid according to 1.5mol. The slurry after acid adjustment is introduced into microwave hydrolysis equipment, pressurized to 0.13Mpa with steam, and maintain pressure for 10 minutes Then turn on the microwave with adjustable pulse width (the microwave power is set to 4 kW, the pulse period is set to 45 seconds, the duty cycle is set to 0.3, and the microwave on-time is set to 20 minutes), when the microwave stops according to the set time , close the steam valve, disconnect the steam, and when the pressure of the equipment drops to 0.02Mpa, the hydrolyzate will be discharged by the residual pressure and enter the next process.

Embodiment 2

[0020] Take 300g of fresh turmeric produced in Yunxi, subdivide it into 40 meshes, centrifuge the liquid and slag after 48 hours of enzymolysis, concentrate in the liquid phase for later use, extract the total saponins of turmeric with a solvent for 5 times in the solid phase, and extract the total saponins of turmeric Combine and add amylase for enzymolysis for 60 hours, adjust sulfuric acid according to 0.8mol, import into microwave hydrolysis equipment, pressurize to 0.1Mpa with steam, and turn on pulse width adjustable microwave after maintaining the pressure for 6 minutes (microwave power is set to 1 kilowatt, pulse The cycle is set to 35 seconds, the duty cycle is set to 0.14, and the microwave on time is set to 24 minutes), when the microwave stops according to the set time, close the steam valve and disconnect the steam, when the pressure of the equipment drops to 0.02Mpa The hydrolyzate is discharged by residual pressure and enters the next process.

Abstract

The invention discloses a method for assisting hydrolyzing saponin by microwave radiation, which comprises the following steps of: performing acid adjustment on a plant or an extract thereof which is subdivided and to be hydrolyzed; introducing the plant or the extract thereof into a microwave-assisted hydrolysis tank; heating with steam to raise the temperature, and maintaining the pressure for 10 to 20 minutes; and starting a pulsewidth adjustable microwave generator for microwave radiation to assisting hydrolyzing for 10 to 30 minutes, and fishing the hydrolysis. Compared with the conventional hydrolysis method, the method can greatly shorten the hydrolysis time, reduces acid consumption and energy consumption, has the advantages of complete hydrolysis, high efficiency, and easy treatment for hydrolysis waste liquor, and is new low-carbon and environment-friendly hydrolysis process technology.

Description

technical field [0001] The invention relates to a method for hydrolyzing saponin, in particular to a method for assisting in hydrolyzing saponin by microwave irradiation. Background technique [0002] The extraction of saponin is usually obtained by acid hydrolysis of saponin-containing plants or crude total saponins extracted from saponin-containing plants. The current hydrolysis method is to put the hydrolyzate into a container that can withstand a certain pressure, and then use electricity to adjust the acid Heating the material to be hydrolyzed in the container by heating, steam, etc., so that the temperature rises to generate pressure, so as to accelerate the hydrolysis of the material to be hydrolyzed in the container, and then extract saponin. Adopt above hydrolysis method to carry out acid hydrolysis, and its hydrolysis time is longer (generally 4-6 hours), and acid consumption is big (2-4mol), and energy consumption is high, and the slag washing amount after hydroly...
