Description
Technical field
The present invention relates to edible oil manufacture field, more particularly to a kind of processing technology of oil tea.
Background technology
Camellia seed oil is commonly called as tea oil also known as camellia oil, camellia seed oil, be from the C. olelferas of Theaceae Camellia Plants into
The pure natural high edible vegetable oil extracted in ripe seed.Tea oil is full of nutrition, fatty acids (unrighted acid 93%,
Middle oleic acid 82%, linoleic acid 11%), camellianin, tea polyphenols, saponin, tannin and rich in antioxidant and with anti-inflammatory effect
Squalene, squalene and Flavonoid substances play the role of anticancer splendid.Tea oil is also rich in vitamin E and calcium, iron, zinc etc.
Trace element is described as the Zn-ef ficiency of " flowers of life " by physician and nutritionist, and content is 10 times of soybean oil, in addition, tea
Amino acid contained type is most in all edible oil in oil, and content of fatty acid, ratio and olive oil are very much like, are known as
The title of " east olive oil " or even the index of some nutritional ingredients are higher than olive oil.Oil tea is the distinctive oil plant in China
Crop, 60,000,000 mu of China oil tea cultivated area, produce ten thousand tons of tea oil 18-20 per year, are equivalent to China's edible oil total quantity consumed at present
L-1.8%, development camellia oleiferaindustry play the role of for China's edible oil safety and people's health it is particularly important.
Invention content
The method that the present invention uses relative low temperature physical squeezing, simple for process, low energy consumption, and oil pump capacity is high, simultaneously effective
The effective active composition of tea oil is remained, obtained tea-seed oil is of light color, and quality is high, and nutrition retains comprehensively, remains tea oil
Intrinsic fragrance.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of processing technology of oil tea, includes the following steps：
(1) tea seed pre-processes：Pericarp is removed after the camellia oleifera fruit natural drying of fresh picking is split to tea seed pericarp, point
It is dried twice, first time drying temperature is 50-55 DEG C, and drying time 50-65min, tea seed moisture is dropped to from 35-40%
20%, second of drying temperature is 60-65 DEG C, the tea seed moisture content 6-10% after drying time 45-55min drying；
(2) it peels off crushing：The camellia seed kernel after drying is taken to carry out separation of peeling off, the amount containing shell of control tea seed kernel≤
0.5%, finally camellia seed kernel is crushed, obtains fine grained camellia seed kernel of the particle diameter at 0.1-0.5 millimeters；
(3) cold pressing is squeezed：It is quenched that the moisture progress that volume ratio is 1-3% is added in camellia seed kernel, while adds in camellia seed kernel
The cavings of weight 5%, then between 10-30 DEG C in a low temperature of extract oil, crude oil is obtained by filtration；
(4) depickling：Crude oil is heated to 60 DEG C -70 DEG C, adds in dilute alkaline soln, stirs 15min, adds weight as crude oil
The water of weight 10%-15%, water temperature be 60 DEG C -70 DEG C, stir 10min, be then cooled to 0-20 DEG C and stand 12-24h, with from
Scheming detaches, and removes oil soap, obtains tea seed crude oil；
(5) distillation dehydration：By tea seed crude oil, decompression dehydration is dried under certain vacuum degree and temperature condition, is obtained
To camellia seed oil, moisture≤1% of camellia seed oil is controlled；
(6) decolorization adsorption：The activated carbon or diatomite that weight is camellia seed oil 4-5% are added at 120 DEG C -130 DEG C,
Under vacuum degree -0.095MPa--0.085MPa, when 25min-30min postcoolings are to 60-70 DEG C, filtering；
(7) winterization degreasing is filtered：Camellia seed oil after decoloration is fitted into maturator, is stirred in the case where rotating speed is 8r/min,
1 DEG C is cooled to, hard fat is made to generate larger crystallization, separation is precipitated, filtering, and oil with hard fat is detached, obtains product oil.
Further, step (3) squeezing is by the way of high-frequency, low dynamics.
Beneficial effects of the present invention：The present invention dries fresh fried flour seed in time, prevents the liter of the acidity of tea oil to greatest extent
Height ensure that the quality into oil expression tea seed, and the high quality oils tea-seed oil to produce pure natural provides guarantee；It is squeezed using low temperature
Oil, the operation temperature of the more traditional hot moulding method of temperature is low, saves high temperature and fries seed process, makes cold press tea oil color shallower, effective to protect
Active constituent is stayed.
