Abstract
The invention provides a physical refining process for non-GMO pressed rapeseed oil in Qinghai-Tibet plateau. The process comprises the processes like cooling of crude plateau non-GMO pressed rapeseed oil, standing and precipitation, rapeseed cake meal addition, a first filtration, a second filtration, and fine filtration. The method comprises the following steps: cooling the crude plateau non-GMO pressed rapeseed oil to 6 DEG C to 8 DEG C by using cooling water with a temperature of 4 DEG C to 5 DEG C; carrying out standing and precipitation for 2 hours so as to remove bottom precipitates; adding a proper amount of the rapeseed cake meal as an adsorbent and a filter aid so as to adsorb non-oil substances like moisture, wax, phospholipid and protein in oil; then carrying out the first filtration; after the first filtration is completed, carrying out the second filtration with different filter mediums; and finally, carrying out fine filtration by using a bag type filter so as to obtain the plateau non-GMO pressed rapeseed oil which has advantages of moderate acid value, standard-achieved moisture, qualified flavor and taste, excellent freezing test, excellent transparency and fully-retained nutrient elements.
Description
Technical field
The present invention relates to grease and produce industrial circle, particularly a kind of Qinghai-xizang Plateau Region non-transgenic squeezing rapeseed oil physical refining process.
Background technology
Qinghai-xizang Plateau Region particularly Qinghai Province is the important locality of China's spring rape seed, and output accounts for about 40% of national spring rape seed, Qinghai-Tibet dry air, day and night temperature is large, and daytime, photosynthesis of plant was strong, and sucrose accumulation is more, night temperatures is lower, and respiration is not strong, and the sugar of consumption is fewer, in Semen Brassicae campestris, organic content enriches, vegetable seed oleaginousness reaches more than 42%, and output is high, and most of kind is Double-low Rape Seed, content of erucic acid is less than 0.65%, and sulphur resources is less than 27.8mmol/g.
Plateau vegetable seed is due to the impact of growth district, environmental factors, make its nutritive element comparatively region, Plain vegetable seed more horn of plenty, but simultaneously because day and night temperature is higher, vegetable seed seed coat wax content is higher, cause the product rapeseed oil anti-freezing property deviation after its processing, directly affects the quality index appearances such as product transparency.
Vegetable seed obtains squeezing crude oil after squeezing, main containing impurity such as a certain amount of moisture content, crumb, fiber, protein, wax, phosphatide, vitamin-E, plant sterols in squeezing crude oil, its subsequent treatment process, traditional method one, adopt natural sedimentation, but need for a long time, sometimes even more than 10 days, in the process, although some mechanical impurity energy precipitate and separate, can there are some reactions in various non-oil substances, cause producing some aldehyde, letones, local flavor, mouthfeel and nutritive value that directly impact is oily, and transparency is not good; Method two, adopt high temperature refinery method, by adding the chemical such as acid, alkali, salt, remove other material in oil, need certain temperature just can complete, even up to about 100-200 DEG C, in the process, beneficial element in oil such as vitamin-E and plant sterol run off in a large number, and because plateau rapeseed oil wax content is higher, transparency that is that cause is not good problem also cannot solve.
Summary of the invention
The object of this invention is to provide a kind of temperature below 8 DEG C, do not add the Qinghai-xizang Plateau Region non-transgenic squeezing rapeseed oil physical refining techniques of other material any.
The present invention is mainly by the following technical programs to realize above-mentioned purpose:
A physical refining process for Qinghai-xizang Plateau Region non-transgenic squeezing rapeseed oil, is characterized in that comprising the following steps:
1., by plateau non-transgenic squeezing crude rapeseed oil oil pump squeeze into cooling pan, in cooling pan, be provided with coil pipe cooling heat exchange device and whipping appts;
2., open handpiece Water Chilling Units, setting water coolant leaving water temperature(LWT) 4 DEG C-5 DEG C, pumps into cooling pan coil pipe refrigerating unit by water coolant, start closed cycle cooling, open cooling pan whipping appts, stirring velocity 60rpm simultaneously, stir about 3-4 hour, oil temperature is down to after below 8 DEG C and stops stirring;
3., staticly settle 2 hours, get rid of the throw outs such as the oil foot of bottom;
4., reopen whipping appts, stirring velocity 80rpm, evenly add cake powder, addition is about 1% of crude oil amount simultaneously;
5., by the crude oil pump in cooling pan squeeze into Chamber Type Diaphragm Filter Press and carry out first time filtration, this pressure filter is provided with filter cloth, and by filtering, the impurity that major part and cake powder are attached together is stayed on filter cloth, obtains initial filter oil product;
6., by the initial filter oil product pump filtered through first time squeeze into second Chamber Type Diaphragm Filter Press and carry out second time filtration, residual impurity in initial filter oil product is removed further;
7., by the oil product after second time is filtered squeeze into bag type filtering machine with pump again and carry out secondary filter, improve oil quality to the utmost, guarantee the visual appearance of oil product, and the nutraceutical active ingredients in oil product is able to abundant reservation.
Wherein, step 6. in pressure filter filter cloth and filter paper are installed as composite filter media.
Wherein, step 7. in filter 5 μm of PO PE NT PTFEs are housed.
The present invention selects more rational low-temperature physics method of refining, refining is carried out to highlands non-transgenic squeezing crude rapeseed oil, both oil quality problem had been solved, oil quality is made to reach national standard, the visual appearance of oil product particularly in oil wax content greatly reduce, processed oil transparency is more outstanding, maintains again the active nutritional component in crude oil to the utmost simultaneously, compared with other technique, there is following advantage:
1, adopt low-temperature refining method, omnidistance oil temperature≤8 DEG C, highlands non-transgenic squeezing rapeseed oil active nutrient component vitamin-E, plant sterol retain more perfect.
2, technological process is all physical process, does not add any chemical substance, and only adopt the fresh cake powder of squeezing byproduct as sorbent material and flocculating aids, food quality is safer.
3, provide the water coolant of 4 DEG C-5 DEG C as refrigerant owing to have employed handpiece Water Chilling Units, oil temperature can fully reduce, while retentive activity component, Wax in rapeseed oil is fully separated out, and remove by filtering, make processed oil transparency better, freezing test better effects if, visual appearance gets a promotion.
4, process period than natural sedimentation and the high temperature refinery method time shorter, whole process, without high temperature, without the need to heating, does not need to adopt the heating unit such as steam, more energy-conservation, non-environmental-pollution.
