Abstract

The invention provides a kind of squeezing of camellia oil and refinery practice, including shell, heat, squeezing, filtering, coldization, distillation, refining, secondary coldization.The present invention heats camellia seed by low pressure microwave, albumen and immobilized artificial membrane in kernel can preferably be destroyed, reduce the moisture content of tea seed, promote the dissolution of oil droplet, improve squeezing oil yield, and for microwave computer heating control at 100 130 DEG C, relatively low temperature can reduce free fatty acid content raising and oil peroxidation product produces, and reduce the difficulty of follow-up refinery practice;Squeezing is squeezed using lower temperature, squeezing is avoided to cause acid value and peroxide value too high, the present invention passes through the secondary coldization PROCESS FOR TREATMENT of coldization distillatory refining, the oyster shell whiting particularly used in refinement step contains micro calcium oxide and chitin, can effectively reduce the content of acid value in camellia oil, peroxide value and poisonous peroxide.

Description

A kind of squeezing of camellia oil and refinery practice
Technical field
The invention belongs to squeezing and the refinery practice of the manufacture craft of edible oil, more particularly to a kind of camellia oil.
Background technology
Camellia oil, also known as camellia seed oil, it is from plant of theaceae oil tea (Camellia oleifera Abel) seeds Middle acquisition, be one of most ancient traditional woody edible vegetable oil in China, its aliphatic acid composition is very much like with olive oil, again It is referred to as " east olive oil ".Also contain tea polysaccharide, tsubakisaponin, flavones, Tea Polyphenols, vitamin and phytosterol in camellia oil It is often edible that there is reduction cholesterol, improve HDL, reduce low-density lipoprotein, drop blood etc. various active material Fat, cardiovascular and cerebrovascular disease is prevented, immunity, radioresistance is improved, removes free radical, pre- preventing tumor and other effects, international food and agricultural organization It has been classified as the health-care edible oil of emphasis popularization.
Most of preparation method of existing camellia oil, which uses, dries, crushes, roll embryo and 110 DEG C of high temperature above steam the works such as stir-fry Sequence, oil is then squeezed by high temperature hot pressing, manufacturing procedure is more complicated, equipment investment is larger, production cost is higher, oil colours is relatively deep, Inferior quality, it is necessary to can turn into one-level expressed oil by the refinings such as depickling, dehydration, decolouring, deodorization, degreasing processing, refine Oil cut rate is relatively low, and refined rear camellia oil loses natural flavour mountaineous.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of squeezing of camellia oil and refinery practice, concrete technology is:
A kind of squeezing of camellia oil and refinery practice, comprise the following steps:
1)Shell, select the camellia fruit of maturation, ted, allow camellia fruit pericarp season crack, remove pericarp and obtain camellia seed, continue The moisture content to camellia seed is tedded in 12-20%;
2)Heating, microwave heating, drying is carried out to above-mentioned camellia seed under environment under low pressure, heating-up temperature is 100-130 DEG C, to mountain Tea seed water content is 2-4%, then naturally cools to normal temperature;
3)Squeezing, above-mentioned camellia seed cold press being squeezed out into camellia oil, press chamber temperature is 100~150 DEG C, oil outlet temperature is 80~ 120℃;
4)Filtering, solid impurity is removed by above-mentioned camellia oil by plate and frame filter press;
5)Coldization, above-mentioned camellia oil is cooled to -5 DEG C~5 DEG C and preserves more than 30h, takes upper strata camellia edible vegetable oil;
6)Distillation, above-mentioned upper strata camellia edible vegetable oil is taken to distill, distillation pressure is 10-60kPa, and evaporating temperature is 130-150 DEG C, is kept 30-50min, it is then 20~25 DEG C in the drop of pressure as little as condensation temperature, takes camellia oil liquid;
7)Refining, is heated to 150-170 DEG C by above-mentioned camellia oil liquid and keeps 5-10min, then cool to 120-140 DEG C, The 1-5% of camellia edible vegetable oil weight oyster shell whiting is added, stirring reaction 50-100min, is subsequently cooled to normal temperature at 130-150 DEG C, Filter off and remove oyster shell whiting;
8)Secondary coldization, above-mentioned camellia oil is cooled to -5 DEG C~5 DEG C and preserves more than 30h, upper strata camellia edible vegetable oil is taken, obtains mountain Tea essential oil.
Further, described oyster shell whiting passes through for fresh shell is polished into powder, 450-550 DEG C of temperature lower calcination 1-4h, Obtained powder is cooled down, shell contains substantial amounts of calcium carbonate and a small amount of chitin, and the decomposition temperature of calcium carbonate is 898 DEG C, By the calcining of 450-550 DEG C of temperature, can destroy shell surrounds and watches structure, discharges micro calcium oxide and chitin, makes Obtaining oyster shell whiting has the effect such as purification, thickening, anti-oxidant.
Further, described step 2)Under the environment under low pressure, pressure 10-60kPa;The microwave heating, microwave Power is 1000-2000 watts.
Further, described step 2)Camellia seed heating in add camellia seed weight 1-5% chaff shell;Chaff shell can Camellia oil is decolourized, while contains a small amount of rice bran oil in chaff shell, camellia oil can be seasoned so that worth camellia Essential oil taste is more sweet and dilitious.
The beneficial effects of the present invention are:The present invention heats camellia seed by low pressure microwave, can preferably destroy kernel Middle albumen and immobilized artificial membrane, the moisture content of tea seed is reduced, promote the dissolution of oil droplet, improve squeezing oil yield, and microwave heats At 100-130 DEG C, relatively low temperature can reduce free fatty acid content and improve and the generation of oil peroxidation product, reduction for control The difficulty of follow-up refinery practice;Squeezing is squeezed using lower temperature, avoids squeezing from causing acid value and peroxide value too high, the present invention Micro oxygen is contained by the oyster shell whiting used in coldization-distillation-refining-secondary coldization PROCESS FOR TREATMENT, particularly refinement step Change calcium and chitin, can effectively reduce the content of acid value in camellia oil, peroxide value and poisonous peroxide;By inspection Survey, the camellia essential oil acid value that makes of the present invention be less than 0.05 mg/g, and peroxide value is less than 1mg/kg, aoxidizes toxic products the third two Aldehyde is less than 1ppb, and water content is less than 1ppm.
