Abstract
The present invention relates to a method for refining nutrient oil, which belongs to the category of blended oil. The present invention economically and effectively improves the quality of edible oil. The nutrient oil is formed by refining raw materials of rice bran oil, rapeseed oil, cotton seed oil and tea seed oil, and by preparation by different formulations. The nutrient oil contains a proper quantity of nutrient components such as linoleic acid and other fatty acid requisite for human bodies, vitamin E, oryzanol, carotene, etc. The nutrient oil is of great benefits to the regulation of brain functions, the reduction of serum cholesterol, and the prevention of arterial sclerosis by eating the nutrient oil for a long time. The present invention has positive significance for changing single edible oil supply variety of China for a long time, sufficiently utilizing oil sources, and improving people health levels.
Description
A kind of edible refining nutritional oil preparation method who belongs to the tempered oil category.
Food oils are the indispensable goods and materials of human lives.Along with economy and science and technology development, people not only need have enough oil quantities for promoting longevity, and the grease of requirement picked-up keeps the balance of lipid acid composition on matter.But lard commonly used contains cholesterol and saturated fatty acid is many, the worry of suffering from hypertension, obesity is arranged, then flavour of candy is heavy, wax content is high for the rice sugar and oil, Oleum Gossypii semen contains also to make us and can fear more than the gossypol, especially the rapeseed oil fatty acids is extremely uneven, erucic acid and linolenic acid are too high, Palmiticacid and stearic acid are low excessively, and being considered to has detrimentally affect to growth of animal and myocardium health.Therefore the formation of the fat that absorbs from edible oil of people and lipid acid does not meet balance and requires.So greasy nutrition reasonably being concocted, is the effective ways that improve the edible oil quality both at home and abroad, strengthen the human physique.Therefore the development and production tempered oil just becomes the developing direction of oils industry.Tempered oil is by refining, and oil quality is to have improved, and nutrition is but lost much.The external way that solves this contradiction is that first degree of depth refining adds nutrition again.This way is that cost height, cost are big, the needs of incompatibility developing country.
Task of the present invention is to provide the method for the refining nutritional oil-tempered oil of a kind of economical and effective preparation.Here it is adopts full refining than the degree of depth (promptly four take off or five take off) with Crude Dapeseed Oil, hair oil extracted from rice husks, hair cotton oil, remove the non-oil substances such as moisture content, impurity, free fatty acids, pigment smell and wax in above-listed three kinds of oil products to greatest extent, reach the balanced principle that is according to the lipid acid composition.Reduce content of erucic acid, and, add the oil product (as rape oil) of smell that people like, be mixed with the nutritional oil-tempered oil of various different ingredients with reference to traditional food custom.
The present invention can implement by two kinds of different operational paths:
1. various greases are pressed different ratios prescription mixing refining:
1. with various greasy crude oil filtering and impurity removings.Try one's best the slag pin in the crude oil is removed, obtain absolute oil preferably, alkali charge during with the minimizing alkali refining.
2. the absolute oil of removal of impurities carries out refining after mixing by the proportioning of rice oil extracted from rice husks 50～60%, rapeseed oil 15～20%, rapeseed oil about 10%, Oleum Gossypii semen 15～20% after filtration.
3. alkali refining will be checked its acid value by above-mentioned formula rate blended absolute oil earlier.Just calculate alkali charge and excess alkali quantity draws total alkali charge according to acid value.Just determine to use concentration of lye according to acid value again.Acid value height, concentration of lye want high.Acid value is low, and concentration of lye is low.General 14～20Bd alkali lye that uses is advisable.When oily temperature rise to 50～55 ℃, begin alkali lye down.And constantly stir.Following alkali finishes and is warmed up to 75～80 ℃.Promptly stop to heat up and stirring.Leave standstill oil is separated with soap stock.When temperature was higher than 80 ℃, soap stock promptly will float, and was difficult for sinking.
4. washing.After soap stock was removed in oil refining, oil will be washed, and washes soap stock contained in the most oil, and water temperature will reach 80～90 ℃.Repeatedly wash, until the water of emitting clear and bright bright till.
5. dehydration.After washing finishes, be heated to 70 ℃.Promptly open the vacuum hydro-extraction drying, control oily temperature and be no more than 110 ℃, vacuum tightness keeps 700～720mmHg, treats that pasta does not have bubble to present, and promptly decolours.
6. decolouring.After oil dehydrates fully, look the cast of oil depth, the activated clay of reusing about 3% by oil carries out vacuum decoloration, and the oil temperature keeps 105～110 ℃, and vacuum tightness 720mmHg post keeps promptly stop vacuum half an hour, filters.Eliminate carclazyte soil pin in the oil.Bleaching time is not long, in order to avoid color and luster is increased on the contrary deeply.
7. deodorization.Deodorization promptly heats up after bleached oil all filters.Open vacuum when oily temperature reaches 110 ℃, vacuum tightness keeps more than the 740mmHg post, and oily temperature reaches more than 150 ℃, otherwise the stink of oil and smell are just not divisible.Deodorization time will keep promptly stopping in 1～2 hour heating, is cooled to 25 ℃ of left and right sides after-filtration, and the oil that filters out is processed oil.
2. various greases are carried out refining (tea oil only carries out alkali refining, washing, dehydration, to keep its inherent fragrance) according to above-mentioned steps respectively.Mix according to the ratio of rice oil extracted from rice husks 50%～60%, rapeseed oil 15～20%, tea-seed oil about 10%, Oleum Gossypii semen 15～20% then and finished product.
By above-mentioned two kinds of finished products that method prepares, its vitamin-E is that 122mg/100 gram oil, carotene are that 0.02mg/100 gram oil, thiaminogen 0.33%, content of erucic acid are reduced between 1.45～18.4% after testing, and oleic acid, linolic acid, saturated fatty acid content ratio of component are more reasonable.Basically reaching 1: 1: 1 best requirement of trophology, is a kind of edible vegetable oil preferably.Changed the situation of for a long time edible single oil products of people.Retail is per jin/25 yuan easy for consumers to accept, the rate of profit of manufacturing enterprise can reach about 12%.If people are for a long time edible, for regulating brain function, reduce serum cholesterol, prevent that arteriosclerosis etc. is all helpful.Simultaneously also produce, make full use of oil sources and created condition for the development oil crops.
