Abstract

The invention relates a preparation method of edible blend oil. The edible blend oil is prepared by using rice oil, rapeseed oil, cotton seed oil and tea seed oil as raw materials through refining and mixing at a formula. The edible blend oil contains a proper amount of fatty acids, vitamin E, oryzanol, carotene and other nutritional components needed by human body. The edible blend oil can be eaten for a long term in order to adjust the brain functions, reduce the serum cholesterol and prevent arteriosclerosis, and is of active significance to changing long-term single variety of edible oil in China, fully utilizing oil sources and improving people's health.

Description

A kind of preparation method of edible refining tempered oil

A kind of method for production of edible refining tempered oil.

Edible oil and fat are the indispensable goods and materials of human lives.Along with development that is economic and science and technology, people, for promoting longevity, not only need enough oil quantities, and require the balance that the grease of picked-up keeps aliphatic acid to form in matter.But conventional lard contains cholesterol and saturated fatty acid is many, there is the worry of suffering from hypertension, obesity, then chaff is highly seasoned, paraffin content is high for rice bran oil, cottonseed oil also makes us fearing more than gossypol, especially rapeseed oil fatty acids is extremely uneven, erucic acid and leukotrienes is too high, palmitic acid and stearic acid too low, be considered to there is harmful effect to growth of animal and cardiac muscle health.Therefore the formation of the fat that absorbs from edible oil of people and aliphatic acid does not meet balance requirement.So reasonably concocting the nutrition of grease, is the effective ways improving edible oil quality both at home and abroad, strengthen human physique.Therefore development and production tempered oil just becomes the developing direction of oils industry.Tempered oil is by refining, and oil quality improves, and nutrition is but lost much.The way of external this contradiction of solution is that first intensive conch adds nutrition again.This way is that cost is high, cost large, is not suitable with the needs of developing country.

Task of the present invention is to provide a kind of economical and effective method manufacturing refining tempered oil.Here it is by Crude Dapeseed Oil, hair oil extracted from rice husks, hair cotton oil adopts full refining (namely four is de-or five de-) compared with the degree of depth, remove the non-oil substances such as moisture content, impurity, free fatty, pigment smell and the wax in above-listed three kinds of oil products to greatest extent, reaching balanced according to aliphatic acid composition is principle, reduce content of erucic acid, and with reference to traditional food custom, add people like the oil product (as rape oil) of smell being mixed with the refining tempered oil of various different formulations.

The present invention can implement by two kinds of different process routes:

1, different proportion formula mixing refining pressed by various grease:

(1) by the crude oil filtering and impurity removing of various grease.Slag pin in crude oil to be removed as far as possible, obtain good absolute oil, alkali charge during to reduce alkali refining.The proportioning of the absolute oil of removal of impurities after filtration by rice oil extracted from rice husks 50 ~ 60%, rapeseed oil 15 ~ 20%, tea-seed oil about 10%, cottonseed oil 15 ~ 20% is mixed.Its optimum proportioning carries out mixing alkali refining by rice oil extracted from rice husks 60 ~ 70%, rapeseed oil 15 ~ 20%, tea-seed oil 5 ~ 10%.

(2) alkali refining.First the absolute oil mixed by above-mentioned formula rate is checked its acid value, draw total alkali charge according to acid value height calculating alkali charge and excess alkali quantity.Determine that acid value is high with concentration of lye according to acid value height again, concentration of lye wants high, and acid value is low, and concentration of lye is low.General use 14 ~ 20Bd alkali lye is advisable.When oil temperature is elevated to 50 ~ 55 DEG C, starts lower alkali lye, and constantly stir, lower alkali is complete is warmed up to 75 ~ 80 DEG C, namely stops rising gentle agitation, leaves standstill and oil is separated with soap stock.When temperature is higher than 80 DEG C, namely soap stock will float, and not easily sinks.

(3) wash.After oil refining removing soap stock, oil will be washed, and wash soap stock contained in most oil, water temperature will reach 80 ~ 90 DEG C.Repeatedly wash, until the water of releasing clear and bright bright till.

(4) dewater.After washing, be heated to 70 DEG C.Namely open vacuum dehydration drying, control oil temperature and be no more than 110 DEG C, vacuum keeps 700 ~ 720mmHg, treats that pasta does not have bubble to present, namely decolours.

(5) decolour.After oil dehydrates completely, depending on the cast of oil depth, the activated bleaching earth of reusing about 3% by oil carries out vacuum decoloration, and oil temperature keeps 105 ~ 110 DEG C, and vacuum 720mmHg post keeps namely stop vacuum half an hour, filters.Eliminate carclazyte soil pin in oil, bleaching time is not long, in order to avoid make color and luster increase on the contrary deeply.

(6) deodorization.Namely heat up after bleached oil all filters deodorization.Vacuum is opened when oil temperature reaches 110 DEG C.Vacuum keeps more than 740mmHg post, and oil temperature reaches more than 150 DEG C, otherwise the stink of oil and smell just not divisible.Deodorization time will keep within 1 ~ 2 hour, namely stopping heating, and filter after carrying out being cooled to about 25 DEG C, the oil filtered out is product oil.

2, (tea oil only carries out alkali refining, washing, dehydration various grease to be carried out refining according to above-mentioned steps respectively, fragrance to keep it intrinsic), then carry out being obtained by mixing finished product according to the ratio of rice oil extracted from rice husks 50 ~ 60%, rapeseed oil 15 ~ 20%, tea-seed oil about 10%, cottonseed oil 15 ~ 20%.Its optimum proportioning is rice bran oil 60 ~ 70%, rapeseed oil 15 ~ 20%, tea-seed oil 5 ~ 10%.

The finished product prepared by above-mentioned two kinds of methods, its vitamin E is 12.2mg/100 gram of oil after testing, calabash radish is plain is reduced between 1.45 ~ 18.4% for 0.02mg/100 gram of oil, oryzanol 0.33%, content of erucic acid, and oleic acid, linoleic acid, saturated fatty acid content Component comparison are reasonable, substantially the best requirement of nutrition 1: 1: 1 is reached, be a kind of edible vegetable oil preferably, change the situation that people eat single oil product for a long time.Retail per jin 1.25 yuan easy for consumers to accept, the profit margin of manufacturing enterprise can reach about 12%.If people eat for a long time, for adjustment cerebral function, reduce serum cholesterol, prevent artery sclerosis etc. all helpful.Simultaneously also for development oil crops produce, make full use of oil sources and create condition.
