Description
Technical field
The present invention relates to fundamentals field, and in particular to a kind of fundamentals technique.
Background technology
Rapeseed oil is exactly the rape oil that we are commonly called as, and is called rapeseed oil, caraway oil, is a kind of food for being squeezed out to come with rapeseed
With oil.Rapeseed oil color is golden yellow or pale brown, there is certain penetrating odor, it is among the people draw be called " green gas taste ".This smell is wherein
Containing caused by a certain amount of sinigrin, but the rapeseed of special quality product kind is then free of this material.
1st, divide from reparation technology, squeezing rapeseed oil can be divided into and leach rapeseed oil.
2nd, whether it is transgenosis to divide from raw material, transgenosis rapeseed oil and non-transgenic rapeseed oil can be divided into.
3rd, divide from the content of erucic acid of aliphatic acid composition, general rapeseed oil and Canola Oil can be divided into.
Typically in buff or brown.0.4-1.0% containing arachidic acid in rapeseed oil, oleic acid 14-19%, linoleic acid 12-
24%, erucic acid 31-55%, leukotrienes 1-10%.From the aspect of nutritive value, human body may be up to rapeseed oil digestibility
99%, and have cholagogic function.In the case where liver is in pathological state, vegetable seed ketone also can be by human homergy.In addition, rapeseed oil
In contain the material such as a small amount of erucic acid and sinigrin, it is considered that these materials are unfavorable to growing for human body.If edible
When with linoleic excellent edible oil is matched, and its nutritive value will be enhanced rich in having.
Existing fundamentals technique is cumbersome, and the rapeseed oil processed is impure, and oil yield is low, and product quality obtains not
To raising.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of fundamentals technique.
In order to solve the above technical problems, the technical scheme is that：
A kind of fundamentals technique, comprises the following steps：
(1) rapeseed is fully dried, it is final to ensure moisture content in 4%-6%；
(2) rapeseed after drying is put into the boiling water that temperature is 90-100 DEG C and soaks 6-10 minutes, while ensure oil
The ratio of weight and number of vegetable seed and boiling water is 1-3:5-12；
(3) rapeseed after step (2) processing is pulled out and cold water flushing is carried out to it, 2-4 times repeatedly；
(4) rapeseed after flushing is added into hydraulic press squeezing, it is 100-110Mpa that average rate, which adds to low pressure, then again will pressure
Power is ramped up high pressure 260-280Mpa, and rapeseed is squeezed, and obtains rapeseed oil first product；
(5) the rapeseed oil first product is subjected to freezing 1-2h, places into the high speed cold that rotating speed is 18000-20000r/min
Freeze in centrifuge and centrifuge 30-50min, remove impurity and obtain rapeseed oil A；
(6) rapeseed oil A is subjected to acid adding degumming, alkali-refining deacidification, charcoal absorption, takes off soap, washed, decolourized, deodorization, produced
Final rapeseed oil finished product.
Further, in the deodorizing technology of the step (6), the speed of heating is：Within 50-60min, temperature from
170-190 DEG C of average rate rises to 240-260 DEG C.
Further, the condition of the deodorizing technology is：Vacuum 200-280Pa, vapor dosage is relative to rapeseed oil
