Description
Technical field
The present invention relates to Oleum Camelliae preparing technical field, be specifically related to a kind of Oleum Camelliae preparation method。
Background technology
Oleum Camelliae, also known as Camellia oil, camellia seed oil, is the distinctive Camellia woody edible oil of south China, is one of big xylophyta oil in the world four。Oleum Camelliae is to extract from oil tea mature seed and obtain, and golden yellow color or pale yellow, clear, abnormal smells from the patient delicate fragrance have the laudatory title of " east olive oil "。
Oleum Camelliae is rich in omega-3 fatty acid and Ω-6 fatty acid, a small amount of poor Saponin and tea polyphenols, without cholesterol, erucic acid and the acid of mountain cornel。Its physicochemical properties are similar to olive oil, have good stability and non-oxidizability, are easily absorbed by the body。The preparation of current Oleum Camelliae mainly adopts hot moulding method and extraction, and wherein hot moulding method is generally squeezed for visitor, and the oil yield of shell is low, and band shell squeezing can adsorb to walk oil content, affects oil yield, and the Oleum Camelliae prepared is with obvious astringent taste；Seed chitin is slightly hard, causes component wear, consumes bigger power。Extraction adopts solvent to extract, operation is: peel off seed coat, with ether after pulverizing, petroleum ether lixiviate 24 hours, after filtration, recycling design obtains seed oil, the height of the relative hot moulding method of pick-up rate of the method Oleum Camelliae, pick-up rate is up to 87%, but owing to extraction uses organic solvent to carry out lixiviate, it is thus achieved that Oleum Camelliae finished product in unavoidable residual organic solvent, causing that Oleum Camelliae is impure, the highest being only capable of of purity reaches 85%。
Summary of the invention
The present invention is directed to the technical problem that above-mentioned Oleum Camelliae pick-up rate machine Oleum Camelliae purity is low, it is provided that a kind of pick-up rate and the high Oleum Camelliae preparation method of purity。
In order to solve above-mentioned technical problem, the present invention provides following technical scheme: a kind of Oleum Camelliae preparation method, comprises the following steps:
Step one, tea fruit are gathered: gather after tea fruit maturation during October, gather complete with a collection of tea fruit in one week；
Step 2, tea fruit process: the tea fruit gathered is disposed within, and indoor temperature is 23～25 DEG C, and indoor humidity is 40～50%, after stacking one week, then are placed under outdoor solar light by tea fruit dry in the sun 3～4 days；
Step 3, the preparation of Semen Camelliae and storage: tea fruit, after dry in the sun, takes out Semen Camelliae from tea fruit, filtered out by the impurity in Semen Camelliae, then Semen Camelliae is dried or in 35～40 DEG C dry to Semen Camelliae moisture content be 10～15%；Semen Camelliae after drying or drying is positioned over lucifuge after being cooled to room temperature, dry place preserves；
Step 4, Semen Camelliae squeezing processing: being put into by Semen Camelliae and carry out squeezing in squeezer and produce Oleum Camelliae and oil cake, pressing temperature is 50～80 DEG C, and oil cake is used for processing crude oil by oil cake resid amount≤6%；
Step 5, refine: crude oil is carried out refining treatment: (1) dehydration, decolouring: crude oil is placed in de-airing mixer and is sequentially carried out dehydration, desolventing technology；(2) vacuum breaker: carry out vacuum breaker process then through vapor distillation, cooling after crude oil decolouring；
Step 6, precipitation, filtration: be placed in the sedimentation tank of 9～10 DEG C to precipitate the crude oil after refine, filter after mix with the Oleum Camelliae in step 4 and both to obtain finished product Oleum Camelliae。
The invention have the benefit that the tea fruit gathered is positioned over temperature by this programme is 23～25 DEG C, humidity is during the indoor stacking one week of 40～50%, guarantee that the tea fruit of outer ripe interior life is thoroughly well-done within the time period, and under the specified conditions of scheme, ensure tea fruit stack during not moldy metamorphism, keep fresh, the Oleum Camelliae prepared is made to keep pure, it is placed under outdoor solar light dry in the sun 3～4 days again, tea fruit is preliminarily dried in the sun, sunlight irradiates in the lower tea fruit promoting after ripening thorough, synthesize the composition interphase interaction of Oleum Camelliae and synthesize Oleum Camelliae, and then improve the content of Oleum Camelliae, basic condition is provided for improving Oleum Camelliae pick-up rate；Semen Camelliae is dried to water content 10～15% and ensures that in the longer resting period, Semen Camelliae does not go bad, and preserves the oil content in Semen Camelliae and purity；It addition, crude oil prepared by oil cake, then the process that crude oil carries out refine adopts physical refining method, it is not necessary to mixes with organic solvent, is absent from organic solvent residual problem；Last filtration and deposition condition, efficiently separate the impurity in Oleum Camelliae and Oleum Camelliae。The present invention program prepares the pick-up rate height of Oleum Camelliae in sum, and purity is high, and pick-up rate is up to more than 96%, high purity more than 95%。
Further, Semen Camelliae is carried out by step 4 Oleum Camelliae squeezing pre-treatment in advance, namely before Semen Camelliae squeezing processing, Semen Camelliae is taken out dry in the sun again 1～2 day。Being dried before squeezing, the oil yield of Semen Camelliae improves again, then in oil cake, resid amount reduces, and crude oil amount reduces accordingly。
Further, in (1) of step 5, during dehydration, setting the vacuum of de-airing mixer as 96KPa, be warming up to Oleum Camelliae temperature for 92～96 DEG C with the speed of 1～1.5 DEG C/min, the rotating speed then regulating de-airing mixer is that 55～65r/min carries out dehydration 40min。Under this condition, the efficiency of refine improves。
Further, in (1) of step 5, after completing dehydration, adding percetage by weight in Oleum Camelliae is the decolorising agent of 2%, and the rotating speed regulating de-airing mixer is 55～65r/min, and decolour 30min。Under this condition, the efficiency of decolouring improves。
Further, in (2) of step 5, vapo(u)rizing temperature is 110 DEG C, distillation time is 300min。While ensureing good purification effect, improve purification efficiency。
