Abstract
The invention relates to a method for pressing rapeseed oil by a physical method, which solves the defects of the prior art that rapeseeds are not good seeds harvested in a planting base and are not picked and separated, more importantly, harmful technologies of leaching, refining by alkali, and the like which can seriously destroy the internal quality of finished oil are adopted to cause the damage and the pollution to the rapeseed oil by a chemical solvent and damage to the natural nutrient content of the rapeseed oil so that the traditional rapeseed oil is harmful to the health and the long life of an eater and in addition, the traditional rapeseed oil is pressed by mixing materials so that the levels of the rapeseed oil can not be divided, and the traditional rapeseed oil can not be instantly eaten and needs to be boiled fro a cold dish with sauce. The method is characterized by comprising the following steps of: after removing dust and ash of good rapeseeds harvested in the planting base and choosing and classifying the good rapeseeds, firing the good rapeseeds between 50 DEG C and 70 DEG C; then, leaching and separating crude oil; heating the crude oil to a temperate ranging from 110 DEG C to 130 DEG C; filtering and separating the rapeseed oil into two levels of a third international standard and a fourth international standard; after cooling the rapeseed oil to a temperature ranging from 5 DEG C to 15DEG C, heating to a temperature ranging from 140 DEG C to 160 DEG C; and refining the rapeseed oil. The invention is used for pressing rapeseed oil.
Description
Technical field
The invention belongs to the large class of B44 in the International Classification of Patents, i.e. isolation technique, particularly a kind of Physical presses the method for rapeseed oil.
Background technology
Traditional Semen Brassicae campestris squeezing process its objective is contained out separating of oil in the Semen Brassicae campestris, its technique generally comprises dedusting, dedust, steaming fry after squeezing, and then become the rapeseed oil finished product through refining, decolouring.Although rapeseed oil can be squeezed and isolate to the method also, its weak point is: oil expression is not the breeding Semen Brassicae campestris of planting base results with Semen Brassicae campestris; The oil expression with Semen Brassicae campestris without selected with separate; Important part also is harmful technique of the havoc processed oil inner qualities such as it takes to leach, alkali refining, has caused used chemical solvents to infringement and the pollution of oil product, thereby has destroyed the natural nutrient component of rapeseed oil, is harmful to eater's health with long-lived; In addition, traditional Semen Brassicae campestris squeezing process is the batch mixing squeezing, so can not divide the number of degrees of the rapeseed oil that produces; Moreover can not instant i.e. usefulness, when especially cold and dressed with sauce, need boil can.
Summary of the invention
In order to solve above-mentioned weak point of the prior art, the purpose of this invention is to provide the method that a kind of Physical presses rapeseed oil.Technical solution of the present invention is: with the dedusting of breeding Semen Brassicae campestris, the dedust of planting base results, roast after selected grading, the duration and degree of heating is controlled between 60 ℃ ± 10 ℃; Then crude oil is isolated in squeezing; This crude oil is heated between 120 ℃ ± 10 ℃; After filtration, be separated into GB three, 4 two grades; After it is cooled between 10 ℃ ± 5 ℃, heat again between 150 ℃ ± 10 ℃; Through refining processed oil.
The advantage that the present invention has compared to existing technology is: carefully-selected in material, the Semen Brassicae campestris of oil expression usefulness must be the breeding Semen Brassicae campestris of planting base results, and need selected, grade; Roast the technique uniqueness, maintain strict control over " duration and degree of heating " and close, solved well the problems such as the color of rapeseed oil and transparency; The present invention adopts integrated technology, thoroughly abolish harmful technique of the havoc processed oil inner qualities such as leaching, alkali refining, eradicated infringement and the pollution of chemical solvents to oil product, thereby the natural nutrient component that has kept rapeseed oil, be conducive to eater's health with long-lived, solve well all unsolved problems of physical method of how long leaning in the rape oil-pressing process, belonged to pioneering at the rape oil-pressing separation field, had novelty, creativeness and practicality.In addition, use the rapeseed oil that method of the present invention processes and need not re-refine, can fry in shallow oil, fry, boil, fried, especially cold and dressed with sauce various foods, convenient, fast.
Embodiment:
The present invention is described in further detail below in conjunction with embodiment: with the dedusting of breeding Semen Brassicae campestris, the dedust of planting base results, roast after selected grading, the duration and degree of heating is controlled between 60 ℃ ± 10 ℃; Then crude oil is isolated in squeezing; This crude oil is heated between 120 ℃ ± 10 ℃; After filtration, be separated into GB three, 4 two grades; After it is cooled between 10 ℃ ± 5 ℃, heat again between 150 ℃ ± 10 ℃; Through refining processed oil.
For pressing rapeseed oil.
