Problems solved by technology

Among them, the pressing method, solvent leaching method and supercritical fluid extraction method have high requirements on the moisture of the oil raw material. When the moisture is low to a certain range, the oil yield of the oil can reach a high level; the aqueous enzymatic method is to fine the oil raw material and add water to adjust the pH Then add biological enzymes to extract the oil under certain conditions. The oil raw materials are crushed as finely as possible, and the moisture requirements of the oil raw materials are also high; and pe

Example Embodiment

[0035] Example one

[0036] Take 1000 kg of fresh selected tea fruits, remove the husks (the husks in the fresh tea seeds are less than 1%) through a shelling machine to obtain fresh tea seeds, which are washed with water and then crushed (the sieve aperture of the crusher is 3mm) ), the crushed fresh camellia seed particles are squeezed out (with 0.1mm gap between squeezing gaps) to obtain solid fiber powder and whey. The moisture content of the whey is 40%. After heating to 65°C, add 9mL anhydrous per 40g of whey The ratio of ethanol: Add absolute ethanol to the system, melt for 30 minutes at a pressure of 0.1 MPa, release the pressure, continue stirring and heating for 1 hour, centrifuge at 1000 rpm for 5 minutes, collect the light phase tea oil, The solvent was recovered at a temperature of 80°C and a vacuum of -0.09MPa for 1.5 hours to obtain deethanolized tea oil, added with activated carbon with 0.5% of the ethanol tea oil mass, adsorbed at a temperature of 30°C for 60 min...

[0038] Example two

[0039] Take 1000 kg of fresh selected tea fruits, remove the husk (the husk in the fresh tea seeds is less than 1%) by a shelling machine, and obtain fresh tea seeds. The fresh tea seeds are washed with water and crushed (the sieve aperture of the crusher is 5mm) ), the crushed fresh camellia seed particles are squeezed out (with 0.3mm gap) to obtain the whey, the moisture content of the whey is 60%, and after heating to 70℃, add 15mL of 80% ethanol aqueous solution for every 40g of whey. Add 80% ethanol aqueous solution to the system, melt for 40 minutes at a pressure of 0.1 MPa, then release the pressure, stir and heat for 50 minutes, centrifuge at 3000 rpm for 4 minutes, collect the light phase tea oil, and place the light phase tea oil at a temperature of 80 Solvent recovery is carried out at a temperature of -0.09 MPa at a temperature of -0.09 MPa for 1.5 hours to obtain de-ethanolized tea oil. The activated carbon with 1.0% of the quality of the ethanol...

Abstract

A camellia oleifera fruit phase separation process comprises: (1) selection, which includes selecting newly-picked fresh plump camellia oleifera fruits; (2) hulling, which includes hulling the camellia oleifera fruits to obtain fresh plump camellia oleifera seeds; (3) washing, which includes washing the camellia oleifera seeds obtained from the step (2) with water; (4) pulverization, which includes putting the camellia oleifera seeds obtained from the step (3) to a pulverizer to obtain camellia oleifera seed granules; (5) phase separation 1, which includes putting the camellia oleifera seed granules obtained from the step (4) to a juice extractor, and performing extruding to obtain solid fiber powder and liquid whey; (6) medium separation, which includes sending the whey obtained from the step (5) to a reaction pot, performing heating, adding a medium, and performing continuous stirring and heating for layering; (7) phase separation 2, which includes centrifuging the emulsion obtained from step (6) to obtain light-phase camellia oil, a heavy-phase tea saponin solution, solid-phase protein, and a starch mixture; and (8) cold extraction. The process is simple in steps and high in oil yield, allows a lot of nutrients to be kept, and fully utilizes the camellia oleifera fruits.

Description

technical field [0001] The invention relates to the processing of oilseed fruit, in particular to a process method of phase separation of camellia oleifera fruit. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae. Camellia oleifera seed is the seed of the camellia oleifera tree. Camellia oil (also known as camellia seed oil, camellia oil, camellia oleifera oil) can be obtained by leaching or pressing. Camellia oil is a healthy and delicious edible oil. It is not only good in color, fragrance and taste, but also has the effect of preventing cardiovascular diseases such as hypertension, coronary heart disease and atherosclerosis, and has important development and utilization value. [0003] At present, the production methods of camellia oil mainly include pressing method, solvent leaching method, aqueous enzymatic method, supercritical fluid extraction method and so on. Among them, the pressing method, solvent leaching met...
