Description
Technical field
The present invention relates to edible oil and fat processing technique field more particularly to a kind of preparation methods of giving off a strong fragrance rapeseed oil.
Background technology
Contain 4% or so glucosinolate in vegetable seed.Glucosinolate is under wet, heat condition, in myrosase
Effect is lower to degrade, and resolves into isothiocyanates, thiocyanates, oxazolidine thione and nitrile compounds, is referred to as total sulfur glucoside,
These decomposition products can inhibit the thyroid gland of animal to the absorption of iodine, lead to metabolic disorder, and have the smell for the people that chokes, therefore,
Giving off a strong fragrance rape oil-pressing technique should remove above-mentioned decomposition product, make in the rapeseed oil after squeezing that total glucosinolate content is small, have
The fragrance of pure, strong rapeseed oil.Giving off a strong fragrance rapeseed oil is in light brown yellow, clear, and aromatic flavour is pure expressed oil, and
Refining process is not added with any chemical addition agent, and intrinsic liposoluble vitamin and other physiological activators are able in rapeseed oil
Retain, nutrient component damages are small, to ensureing people's safe edible vegetable oil, meet the needs of people are to healthy edible grease, have
It is significant.
At present, the production method of domestic giving off a strong fragrance rapeseed oil is that the vegetable seed after cleaning is directly fried seed in coal-fired directly fiery roller
Frying, oil expression or the embryo piece for the vegetable seed after cleaning being rolled into 0.4mm thickness in machine enter back into directly fiery roller seeds frying machine
Interior frying, oil expression, the giving off a strong fragrance rapeseed oil produced have the smell of one strong people that chokes, and the purpose of aromatic flavour is not achieved,
Some harmful ingredients do not remove, and Residual oil height, oil yield efficiency are low in cake, cause the wasting of resources, in particular by
The mode of heating of coal-fired directly fire generates exhaust emission environment, do not meet safely, the modern production code requirement carried out production strictly in line with rules and regulations.
A kind of simple Degumming method of giving off a strong fragrance rapeseed oil is disclosed in the prior art, but is covered and taken off using addition in this method
The degummings such as soil, silicate, modified alta-mud adsorbent carries out degumming, has used chemical addition agent；It discloses again in the prior art
A kind of novel rapeseed oil fumet and its application process in giving off a strong fragrance rapeseed oil is prepared use a variety of chemistry in this application method
Substance synthesizes fumet with rapeseed oil mixing preparation into giving off a strong fragrance rapeseed oil, is equally added to chemical addition agent, belongs to chemical method；
Therefore, at present, the prior art need it is a kind of it is new, harmful components can be removed and do not add chemical addition agent, physiological activity object
Matter be able to retain, strong fragrance can be generated, non-environmental-pollution prepare giving off a strong fragrance rapeseed oil method replacement.

| Common process | 300~400ppm | 1.5% | 0.8% |
As can be seen from the above table:Total glucosinolate content≤120ppm in giving off a strong fragrance rapeseed oil produced by the present invention, it is total in rape cake
Glucosinolate content≤0.8% leaches total glucosinolate content≤0.4% in rapeseed dregs, far below glucosinolate content total in common process.
Giving off a strong fragrance rapeseed oil prepared by the present invention has the advantages that：
(1) aromatic flavour, harmful substance contents are few：The synergistic effect of cigarette technique is raised in used wetting tempering and frying,
So that glucosinolate resolves into isothiocyanates, thiocyanates, oxazolidine under wet heat condition, under the action of myrosase
Thioketones and nitrile compounds are separated raising cigarette process, and it is extremely low to dissolve total glucosinolate content in the oil after squeezing, makes finally to press
The rapeseed oil come of squeezing out has pure, strong fragrance and flavour；
(2) Residual oil is low in rape cake, oil yield efficiency is high：After vegetable seed fully absorbs moisture, the albumen qualitative change during frying
Property it is thorough so that intracellular creamy texture destroys, and protein reduces the compatibility of grease, and the channel of grease outflow increases, together
When, the oil extruder gun pressure power of 4 grades of squeezings of use is high, reaches 28~30Mpa, down to≤6%, vegetable seed goes out Residual oil in rape cake
Oily efficiency >=90%, the utilization of resources are abundant；
(3) good product quality：It is not added any chemical additives in preparation process, the giving off a strong fragrance rapeseed oil after refining is purer
Just, total glucosinolate content≤120ppm；Total glucosinolate content≤0.8% of rape cake after squeezing, after routinely leaching, rapeseed dregs total sulfur
Salidroside content≤0.4% reaches feed rapeseed dregs standard；
(4) no pollution, zero-emission：Production process does not have any discharge of wastewater, the colloidal substance after Polish filtration mainly into
It is divided into phosphatide and grease, mixes with the rapeseed dregs after leaching and sold as feed, while improve the nutritive value of rapeseed dregs, do not have
There is any solid waste.
It should be noted that and understand, in the spirit and scope for not departing from appended claims the claimed invention
In the case of, various modifications and improvements can be made to the present invention of foregoing detailed description.It is therefore desirable to the technical solution of protection
