Abstract
The present invention relates to vegetable edible oil extracting method field, specifically a kind of camellia oil preparation method.Fresh tea seed is taken, is dried under vacuum, add subcritical dimethyl ether solution, being put into extraction kettle carries out supercritical CO2Extraction, enzymolysis and 3-4h of Maillard reaction are carried out under conditions of camellia oil foot is slowly stirred after 1398 neutral proteinases and alpha amylase at 38-42 DEG C of temperature, camellia oil is obtained, the camellia oil preparation method that the present invention is provided, the oil yield of camellia oil can be improved, and using two methods of the extraction of subcritical dimethyl ether solution and supercritical carbon dioxide extracting, the loss of active material during liquefaction can be substantially reduced, improve the quality of camellia oil, and Maillard reaction is carried out using cold-adapted enzyme, oil foot can significantly be utilized, improve the utilization rate of camellia seed, turn waste into wealth, the fragrance of generation can also make the camellia oil of preparation more aromatic.
Description
Technical field
The present invention relates to vegetable edible oil extracting method field, specifically a kind of camellia oil preparation method.
Background technology
Camellia seed oil is the fully natural green edible oil obtained from Theaceae tea oil tree seed, its golden yellow color or pale yellow, and quality is pure
Only, clear, smell delicate fragrance, good taste, there is the laudatory title of " east olive oil ".CDC is sought
Support with food security the comparative study of tea oil and olive oil is shown, the composition of tea oil and olive oil in spite of similarity, but
The dual-use function of tea oil dietotherapy is actually superior to olive oil, also superior to other any greases.After testing, unsaturated lipid in olive oil
The content of fat acid is 75%~90%, and the content of unrighted acid is up to 85%~97% in tea oil, is the hat of various edible oils.
Meanwhile, the active ingredient such as tannin, squalene for containing in camellia seed oil can also remove interior free yl, reach anti-aging,
Improve the effect such as colour of skin.
Used as high quality food oil, particularly it has peculiar flavour to tea oil, and with unique health-care effect, all obtains all the time
To the favor of broad masses.With living standards of the people raising and build a well-off society in an all-round way, it is edible to high-quality healthy flavor
The demand of oil gradually expands, and the shared share in edible oil high-end market of local flavor tea oil also accordingly increases, and camellia oil has well
Market prospects, and current production rate is extremely limited.
Camellia oil is mainly after tea seed is squeezed through degumming, depickling, except the refinement treatments such as soap, decolouring, deodorization, dewaxing are obtained.
Traditional production method has the following disadvantages：Oil yield is low, a large amount of active materials contained in tea seed such as squalene, Ve and
Phytosterol etc. is big in the subtractive process loss amount of tea oil, and the recovery rate of active material is low to cause that tea oil quality is relatively low, and operation is various,
Production cycle is long.
The content of the invention
In order to solve the above problems, the invention provides a kind of camellia oil preparation method.
Technical scheme is as follows：
A kind of preparation method of camellia oil, its preparation method is as follows：
(1) fresh tea seed, is taken, is dried, shelled, selecting excellent impurity elimination；
(2) 60-80 DEG C, by the tea seed of select under vacuum conditions, is heated to, drying to moisture is less than 10%, cooling；
(3), the tea seed kernel that will be dried is crushed, and adds subcritical dimethyl ether solution, static, filtering；
(4), filtrate is centrifuged, the camellia oil of first time is obtained；
(5), the tea seed kernel after filtering is put into extraction kettle carries out supercritical CO2Extraction, 30-50 DEG C of extraction kettle temperature, pressure
20-40MPa, extraction time 3-4h, obtain secondary camellia oil and oil foot；
(6) enter under conditions of, camellia oil foot is slowly stirred after 1398 neutral proteinases and alpha amylase at 38-42 DEG C of temperature
Row enzymolysis and 3-4h of Maillard reaction；
(7), by step 4) and step 5) prepare camellia oil twice mixing, carry out depickling treatment；
(8), by step 6) the fragrance extraction grease that reaction produces fragrance is carried out, dewater treatment is carried out, obtain Aroma camellia oil；
(9), by step 7) and step 8) camellia oil mixing, that is, obtain camellia oil.
Further, the preparation method of above-mentioned camellia oil, the camellia oil is filling using nitrogen.
Beneficial effects of the present invention：
Compared with prior art, the camellia oil preparation method that the present invention is provided, can improve the oil yield of camellia oil, and using sub-
Two methods of the extraction of critical dimethyl ether solution and supercritical carbon dioxide extracting, can substantially reduce active material during liquefaction
Loss, improves the quality of camellia oil, and carries out Maillard reaction using cold-adapted enzyme, can significantly utilize oil foot, improves camellia
The utilization rate of seed, turns waste into wealth, and the fragrance of generation can also make the camellia oil of preparation more aromatic.
Specific embodiment
A kind of preparation method of camellia oil, its preparation method is as follows：

(3), the tea seed kernel that will be dried is crushed, and adds subcritical dimethyl ether solution, static, filtering；
(4), filtrate is centrifuged, the camellia oil of first time is obtained；
(5), the tea seed kernel after filtering is put into extraction kettle carries out supercritical CO2Extraction, 30-50 DEG C of extraction kettle temperature, pressure
20-40MPa, extraction time 3-4h, obtain secondary camellia oil and oil foot；
(6) enter under conditions of, camellia oil foot is slowly stirred after 1398 neutral proteinases and alpha amylase at 38-42 DEG C of temperature
Row enzymolysis and 3-4h of Maillard reaction；
