Description
Technical field
The present invention relates to the processing technique fields of rapeseed oil, relate in particular to a kind of physics cold pressing process of rapeseed oil.
Background technique
Currently, people pay attention to edible oil it is healthy and safe it is more be tea-seed oil and rapeseed oil.Rapeseed oil is using rape
Seed squeezing processing after obtained oil, also known as rape oil, generally conventional rape oil processing method is to dry the vegetable seed after acquisition,
Steaming fries, rolls embryo, squeezing, Dip goes out, the processes production such as addition active matter carclazyte is oily in refining process,
The method of existing rape oil expression, which is still in, will pass through the stage of steaming and frying technique in vegetable seed, and steams the high temperature fried and hold
The nutritional ingredient in oil is easily lost, affects fragrance and the shelf-life of active material and rape itself, traditional refinery practice is also
The crude oil come of squeezing out is dried in vacuo, add the chemical components such as carclazyte, alkali, salt, water, vacuum decoloration, high temperature high vacuum
The process flows such as deodorization processing, equally can be to palmitinic acid C16:0, linoleic acid C18:2, the erucic acid C22:1, wood tar in hair rape oil
The effective ingredients such as sour C24:0 cause largely to lose, in addition, containing more impurity, vegetable seed scurf, phosphatide, trip in hair rape oil
From fatty acid, carbohydrate, moisture content, protein and their degradation product, oxide, the appearance luster of oil is not only affected,
Also directly second of pollution of contact oil, influences the interior quality of oil, it is therefore desirable to remove from office to existing rape oil squeezing process
Newly.
Summary of the invention
It the purpose of the present invention is overcoming above-mentioned technological deficiency, provides a kind of simple and easy to do, is not lost in oil in expressing process
Nutrition, do not generate secondary pollution in refining process, the limpid appearance color of rapeseed oil true qualities is presented in obtained squeezing rape oil
Rape oil mark is squeezed better than DB53/T 288-2009, GB/T23373-2009, GB/T22460-2008, GB/T 5530-2005 in pool
The physics cold pressing process of quasi- rapeseed oil.
Realize the physics cold pressing process the technical solution of the present invention is as follows: a kind of rapeseed oil, method includes the following steps:
(1) vegetable seed of acquisition is dried, the biochemical basis acted on using seed afterripening promotes vegetable seed after-ripening；
(2) vegetable seed of after-ripening is subjected to cleaning removal of impurities, rapeseed is squeezed using cold press process；
(3) crude oil and rape cake that the vegetable seed after squeezing is collected；
(4) it is 30 DEG C in temperature by crude oil, is filtered using 50 mesh or 60 mesh filter clothes and obtains semi-finished product rape oil with brilliant growing the grain；
(5) semi-finished product rape oil is introduced into the warm bucket that temperature is 280 DEG C -380 DEG C, adjusting revolving speed is 30/min, by semi-finished product
Rape oil disposably decolourizes, depickling, degumming, deodorization, is filtered to obtain rape oil using 100 mesh, and it is 50 DEG C that rape oil, which is introduced temperature,
Insulation barrel must refine pure rape oil by multiple filtration.
It preferably, further include drying vegetable seed to be placed on 0 DEG C -20 DEG C of low temperature environment and store to dish in the step (1)
Seed after-ripening.
Preferably, vegetable seed after-ripening to aridity is 80-85% in the step (1).
Preferably, the temperature of cold press process described in the step (2) is 18-33 DEG C.
Preferably, semi-finished product rape oil is introduced into the warm bucket that temperature is 380 DEG C in the step (5), adjusting revolving speed is 30/
Semi-finished product rape oil is disposably decolourized, depickling, degumming, deodorization, is filtered to obtain rape oil using 100 mesh, rape oil is introduced by min
The insulation barrel that temperature is 50 DEG C, must refine pure rape oil by multiple filtration.
The invention also discloses a kind of rapeseed oils, it is to process to obtain by the physics cold pressing process of any of the above-described kind of rapeseed oil
's.
Compared with prior art, the beneficial effects of the present invention are: 1, by the way that vegetable seed is dried, utilize seed afterripening effect
Biochemical basis promotes vegetable seed after-ripening, improves raw material vegetable seed quality, ensure that material quality；2, the vegetable seed bits shadow in dark pool is avoided
Ring product color；3, the inferior vegetable seed raw material of mildew is avoided to enter in production technology, ensure that squeezing crude oil quality and
Mitigate cost of investment；4, rapeseed oil color depth and burning are avoided, ensure that rapeseed oil intrinsic smell and flavour；5, disposable
280 DEG C of -380 DEG C of high temperature, 50 DEG C of filter at low temperature refining techniques avoid caustic soda in normal refinery activities, salt depickling, carclazyte activity
The pollution that chemical substance caused by water decolorization technique is directly contacted with rapeseed oil, at the same also avoid the vacuum drying in tradition,
The distortion of vegetable seed incense oil taste when vacuum decoloration, high-temperature vacuum deodorization, be effectively retained the following fatty acid of 14 carbon in rapeseed oil,
Palmitinic acid C16:0, palm monoenoic acid C16:1, lignoceric acid C24:0 erucic acid C22:1, stearic acid C18:0, oleic acid C18:1 etc. have
Imitate composition；The limpid appearance luster of rapeseed oil true qualities is presented in squeezing rape oil through examining the present invention to obtain, is better than DB53/T 288-
2009, GB/T23373-2009, GB/T22460-2008, GB/T 5530-2005 squeeze rape oil standard.
