Embodiment 1

[0021] Weigh 100 g of Camellia oleifera cake after the oil has been extracted, pulverize through a 10-mesh sieve, then add 3 times the concentration of 70% ethanol-containing organic solution, and then stir evenly. Fix the container, and immerse the horn in the ultrasonic instrument into the mixed solution, adjust the depth of the horn immersed in the mixed solution to 20 mm, and adopt a titanium alloy exponential longitudinal vibration horn. Adjust the ultrasonic frequency to 20KHz, the ultrasonic power to 800w, and the ultrasonic action time to 20min. After the leaching is completed, carry out suction filtration and separation, recover ethanol to obtain 32.67g of crude tea saponin, and dilute it into a 200ml solution with water; add 100ppm of flocculant, let it stand for clarification, remove the precipitate, and obtain the tea saponin extract; Then the tea saponin extract was purified by ultrafiltration, using a modified cellulose membrane with a molecular weight cut-off of...

Embodiment 2

[0023] Take by weighing 100 g of Camellia oleifera cake after the oil has been extracted, pulverize through a 20-mesh sieve, then add 4 times the weight of an 80% ethanol organic solution, and then stir evenly. Fix the container, and immerse the horn in the ultrasonic instrument into the mixed solution, adjust the depth of the horn immersed in the solution to 18mm, and adopt a titanium alloy exponential longitudinal vibration horn. Adjust the ultrasonic frequency to 20KHz, the ultrasonic power to 1000w, and the ultrasonic action time to 20min. After the leaching is completed, carry out suction filtration and separation, recover ethanol to obtain 33.89g of crude tea saponin, and dilute it with water into a 200ml solution; add 150ppm of flocculant, let it stand for clarification, remove the precipitate, and obtain the tea saponin extract; Then the tea saponin extract was purified by ultrafiltration, concentrated to 28.5ml with a modified cellulose membrane with a molecular weigh...

Embodiment 3

[0025] Weigh 100 g of Camellia oleifera cake after the oil has been extracted, pulverize through a 10-mesh sieve, then add 5 times the weight of an 80% ethanol organic solution, and then stir evenly. Fix the container, and immerse the horn in the ultrasonic instrument into the mixed solution, adjust the depth of the horn immersed in the solution to 20 mm, and adopt a titanium alloy exponential longitudinal vibration horn. Adjust the ultrasonic frequency to 20KHz, the ultrasonic power to 1000w, and the ultrasonic action time to 25min. After the leaching is completed, carry out suction filtration and separation, recover ethanol to obtain 34.55g of crude tea saponin, and dilute it with water to form a 200ml solution; add 200ppm of flocculant, let it stand for clarification, remove the precipitate, and obtain the tea saponin extract; Then the tea saponin extract was purified by ultrafiltration, concentrated to 33ml with a modified cellulose membrane with a molecular weight cut-off...

Abstract

The present invention is ultrasonic process of preparing theasaponin and belongs to the field of agricultural side product processing technology. The technological scheme is that tea seed cake residue after extracting oil is processed through crushing, mixing with organic solvent, ultrasonic leaching, separating, recovering solvent, ultrafiltering to purify and to obtain theasaponin concentrate, decolorizing and drying to obtain theasaponin product. The present invention has the beneficial effects of physical extraction process caused high theasaponin extracting rate, high product purity and quality, simple technological process with low power consumption and low production cost, less pollution, etc.

Description

technical field [0001] The invention relates to a method for preparing tea saponin by ultrasonic waves, which belongs to the field of deep processing of agricultural and forest by-products. Background technique [0002] Camellia oleifera is a unique woody oil resource in my country. Generally, the oil content of camellia oleifera seeds is 25% to 33%, and its fatty acid composition is very similar to that of olive oil. It is a high-quality edible oil. At present, the output of tea seeds planted in my country is about 650,000 tons, and about 150,000 tons of camellia oil and about 500,000 tons of camellia seed cakes are produced every year. Camellia oleifera seed cake contains 10%-20% tea saponin, 12%-16% crude protein, and about 16% crude fiber. The current situation in our country is that most of the camellia oleifera cake is burned as fuel or exported to foreign countries cheaply, resulting in a great waste of resources. The development of Camellia oleifera planting must p...
