[0005] Chinese patent CN103819517B discloses a preparation method of tea saponin, which includes the following steps: a, extruding and expanding the tea seed dregs; b, performing ball milling micronization on the tea seed dregs; c, adding cold water and protease Extract the residual tea seed oil in the tea seed meal; d, add hot water to adjust the ratio of ethanol to water to extract tea saponin; the extraction rate of the tea seed meal residual oil is 95-98%, and the extraction rate of tea saponin can be 47-55% %, content 76-85%; this method adopts the residual oil extracted by cold water and enzyme preparation to obtain tea oil with better quality, but the extraction rate and purity of tea saponin are not high, resulting in waste of resources
Zhong Haiyan et al. studied the characteristics of the mixed solvent composed of 95% ethanol and hexane, the miscibility of camellia oil to the mixed solvent, and the leaching process of the dried cake of camellia oleifera by the mixed solvent. The results showed that: the volume ratio of 95% ethanol and hexane In the range of 7:3-4:6, the two can be miscible; when the volume ratio of 95% ethanol and hexane is 5:5, the leaching temperature is 58°C, the solid-liquid ratio is 2:1, and the leaching time is 5h , the extraction of residual oil and naphthalene saponin is more suitable; the yield of residual oil and naphthalene saponin is respectively 3.6% and 7.0%. Leaching of Camellia oleifera dry cake will have adverse effects on the quality of camellia oil

Embodiment 1

[0050] The present embodiment provides a kind of comprehensive utilization method of tea dead, and described method is specifically as follows:

[0051] Weigh 30Kg Chaku, grind it into 100 mesh particles, put it into the ultra-high pressure extraction tank, add 120L of sodium hydroxide solution with a concentration of 1.3g / L that has been heated to 55°C in advance, raise the pressure to 300MPa in 6 minutes, and keep After pressing for 3 minutes, the pressure relief is completed within 15 seconds, and the extract is released after repeating this process (boosting-pressure-holding-pressure relief) 6 times.

[0052] Collect 10 batches of the above-mentioned extracts, centrifuge, and take the upper layer oil (10.5Kg upper layer oil) and the lower layer clear liquid respectively for later use.

[0053] Add 0.209Kg white clay to the upper layer oil, stir and decolorize for 15min at a vacuum of 6KPa and 70°C, pump it into a filter press for filtration, add 1.0L soft water, stir, cent...

Embodiment 2

[0058] The present embodiment provides a kind of comprehensive utilization method of tea dead, and described method is specifically as follows:

[0059] Weigh 30Kg Chaku, crush it into 150 mesh particles, add it to the ultra-high pressure extraction tank, add 150L of sodium hydroxide solution with a concentration of 1.8g / L to it, heat the sodium hydroxide solution to 60°C in advance, and raise the pressure to 400MPa, after holding the pressure for 4 minutes, the pressure is released within 20 seconds, and the extract is released after repeating this process 7 times.

[0060] Collect 10 batches of the above extracts, centrifuge, take the upper layer oily matter, get 10.7Kg upper layer oily matter, intercept the clear liquid as the extracting liquid; add 0.16Kg acid clay to the upper layer oily matter, and stir at a vacuum degree of 8KPa and 75°C Decolorize for 10 minutes, pump it into the filter press for filtration, add 0.96L soft water, stir, centrifuge, and deodorize with wa...

Embodiment 3

[0065] The present embodiment provides a kind of comprehensive utilization method of camellia oleifera seed, and described method is specifically as follows:

[0066] Weigh 30Kg of dried and roasted tea seeds, crush them into 100-mesh granules, add them to an ultra-high pressure extraction tank, add 180L of sodium hydroxide solution with a concentration of 1.0g / L to it, and heat the sodium hydroxide solution to 50°C in advance. Boost the pressure to 300MPa in 6 minutes, hold the pressure for 3 minutes, and release the pressure within 15 seconds. Repeat this process 8 times and release the extract.

Abstract

The invention discloses a comprehensive utilization method of camellia seeds or sasangua cakes. The method comprises the following steps: (1) carrying out ultra-high-pressure extraction on the camellia seeds or sasangua cakes in an alkaline condition and centrifuging the obtained extract solution to obtain an upper oily matter and a subnatant; (2) sequentially decolorizing and filtering the upper oily matter, adding soft water and stirring, centrifuging and separating to obtain a crude camellia product; (3) carrying out deodorizing treatment on the crude camellia product, carrying out cooling, heat preservation, heating, filter pressing and continuous vacuum drying in sequence to obtain the finished camellia product; (4) carrying out decolorizing treatment on a subnatant, and carrying out ethyl acetate extraction, ultrafiltration membrane penetrating purification and nanofiltration membrane filtering in sequence to obtain a trapped fluid; and (5) carrying out vacuum concentration on the trapped fluid, adding acetone, adding an acid liquid to adjust the pH value, cooling and standing, separating out crystal and filtering to obtain tea saponin crystal. According to the method disclosed by the invention, tea oil and tea saponin with relatively high quality can be obtained, and the comprehensive utilization method has great social and economic value and significance.

Description

technical field [0001] The invention belongs to the technical field of extraction technology, and in particular relates to a comprehensive utilization method of camellia oleifera seeds or tea dead. Background technique [0002] Camellia oleifera is an important oil plant in the hilly areas of southern my country. my country is the country with the highest yield, the widest distribution and the most varieties of camellia oleifera seeds in the world, with an annual output of about 549,800 tons of camellia oleifera seeds, and an average annual output of 397,100 tons of camellia oleifera seeds, a by-product of camellia oleifera. As early as 400 years ago, there was a record in "Compendium of Materia Medica": "Tea has seeds that grow and grow wild: the seeds are used by those who plant them. Throat, while Fujian people eat it with squeezed oil." Camellia oleifera (also known as tea seed meal) is the residue of tea seeds after processing and extracting oil, and is the main by-pr...
