Abstract
The invention belongs to the field of vegetable oil refinement, in particular relates to a corn oil with high vitamin E and phytosterin contents and a production method thereof. 100g of corn coil contains 90mg to 120mg of vitamin E and 90mg to 1300mg of phytosterin. The production method of the corn oil comprises the following steps: arranging a drip catcher behind a deodorizing tower to collect deodorized distillate; removing impurities; distilling the deodorized distillate to remove dissociative fatty acid; adding alcohol to mother liquid after removing the fatty acid to further remove remnant fatty acid; using a decoloring agent to absorb and decolor the mother liquid; and returning the obtained qualified treatment liquid to product oil, uniformly mixing the qualified treatment liquid and the product oil, storing and packaging the mixture. Compared with the corn oil prepared by the traditional refinement technology, the corn oil is improved in the vitamin E and phytosterin contents by 30 to 50 percent.
Description
Technical field
The invention belongs to the vegetable oil refining field, specifically, relate to the corn oil product and the production method thereof of a kind of homovitamin E, phytosterol content.
Background technology
Corn oil is the vegetable fat that is made by maize processing, is a kind of high-quality edible vegetable oil, is oil for cooking preferably, also is the best oil product of processed food.In addition, corn oil mixes with solid grease (as brown tung oil) and the mixing corn oil made, can be widely used in metric system cake and the various instant food, with fast food, instant noodles, the pot foods features good taste that corn oil is made, long shelf-life.
Mainly contain 86% unrighted acid in the corn oil, wherein linoleic acid accounts for 55%, and oleic acid accounts for 30%, also contains nutritional labelings such as vitamin E, vitamin A, phytosterol, lecithin, coenzyme, beta carotene.Wherein linoleic acid is an essential fatty acid, is the part that constitutes human body cell, can combine with cholesterol in human body, is flowability and eubolism, and the effect of angiocardiopathy such as atherosclerotic of preventing and treating is arranged.
Vitamin E has the function that reduces body's cholesterol, hypotensive, softening blood vessel, increase human muscle and heart, cardiovascular system, prevention and improve artery sclerosis, reduce effects such as heart disease generation, vitamin E can be removed the oxygen radical in the body, Wheat Protein to human body cell division, certain effect that delayed senility, has the body of enhancing resistivity, and have certain antitumaous effect, can also suppress to alleviate the generation and the outbreak of human body various disease conditions.
Phytosterol is the main component of corn oil unsaponifiable matter.There is research to point out that the sterol content of corn oil will be higher than sunflower oil and soybean oil.Phytosterol by suppress enteron aisle to the absorption of cholesterol, promote the alienation of cholesterol, in liver, suppress three kinds of modes of action of biosynthesis of cholesterol, significantly reduce cholesterol.In addition, zoopery and human trial prove, that phytosterol also has is anticancer, quasi-hormone activity, anti-inflammatory antipyretic, immunological regulation, adjusting growth and function such as antiviral.
Because the These characteristics of corn oil, and also because of it is of high nutritive value, the sense of taste is good, and not perishable, thereby popular to people deeply.
But because oil refining process, in the commodity corn oil of current listing, vitamin E and phytosterol content are also not high enough, influence its nutritive value.
The refinery practice of existing corn oil is: corn oil earlier through coming unstuck, depickling and decolouring handle and remove dephosphorization matter part, aliphatic acid and coloring matter, carry out the stripping deodorization again, the mode of operation of stripping deodorization not only directly influences the quality of oil, and nutriment vitamin E and phytosterol reservation amount what are determining.Have many free fatties in the distillate of stripping deodorising process, also have simultaneously usury to be taken out of in a large number with the vitamin E of value and phytosterol and run off very much.According to detecting data, contain unsaponifiable matter 10-30% in the corn oil deodorization distillate, wherein, about 40% is phytosterol, the 15%th, natural VE.
Contained phytosterol and natural VE are not done further extraction, and are undersold as waste material with free fatty often because of separation difficulty in the distillate of above-mentioned deodorising process, cause the wasting of resources; Free fatty after separating is wherein incited somebody to action by indivedual enterprises, carries out loaded down with trivial details steps such as cold analysis, isolated by filtration, dehydration and level Four molecular clock again, from wherein extracting vitamin E, has both needed complicated complete set of equipments, factory building and great amount of investment,
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the content of vitamin E and phytosterol in the raising commodity corn oil, increase the nutritive value of corn oil, the invention provides the corn oil of a kind of homovitamin E, phytosterol content, wherein the content of vitamin E is 90-130mg/100g, and the content of phytosterol is 1200-1600mg/100g.
For convenience, on the basis that does not increase existing equipment and investment, produce the corn oil product of above-mentioned high standard, the inventor has proposed the processing recovery scheme that a kind of new refining and deodorizing slips out thing, its principal character is that the deodorization with the refining process deodorization procedures slips out thing and collects, through the separation removal free fatty, the qualified treatment fluid of gained directly returns in the refined oil.The content of vitamin E and phytosterol has improved 30-50% than prior art in the finished product corn oil thereby make.
Concrete separation recovery and treatment method is as follows:
(1) behind the deodorization tower, trap is set, is used to collect deodorization distillate;
(2) remove impurity;
(3) the deodorization distillate distillation is removed free fatty;
(4) add alcohol in the mother liquor after removing aliphatic acid, wherein residual aliphatic acid is further removed;
(5) with decolorizer mother liquor is carried out adsorption bleaching;
(6) the qualified treatment fluid of gained is returned in the product oil, after mixing, store, pack.
Wherein said trap is installed in the inside of stripper.
The process conditions that wherein said distillation removes free fatty are: vacuum 1～4Pa; 100～115 ℃ of temperature.
Wherein the process conditions of said esterification are: mother liquor: alcohol: the part by weight of alkali is 60: 8～10: 0.6～1.
Wherein said decolorizer is active carbon and/or atlapulgite.
Use above invention, obtained effect preferably: the content of the corn oil vitamin E of prior art is 50-80mg/100g, the content of phytosterol is 650-900mg/100g, the content of corn oil vitamin E of the present invention is 90-130mg/100g, and the content of phytosterol is 1200-1600mg/100g.The corn oil vitamin E that patent of the present invention is produced and the content of phytosterol improve 30-50% than traditional refinery practice.
Vitamin E is a kind of antioxidant, can remove the oxygen radical in the body, has the body of enhancing resistivity, improves effects such as blood circulation, angiocardiopathy preventing.
Phytosterol has the important physical active function to human body, can suppress the absorption of cholesterol in intestines, and clinical use proof has certain effect for reducing fat, and can prevent and treat the heart disease of coronary disease atherosclerotic class.
The corn oil that this patent method is produced, significantly improved the content of vitamin E and phytosterol, the nutritive value and the commodity value of finished product corn oil have been increased, and vitamin E wherein and phytosterol are pure natural, help absorption of human body and utilization, further improved the nutritive value of corn oil, and in the corn oil of produced in conventional processes, add synthesising complex E and compare with phytosterol that to have a cost low, characteristics such as composition is natural have good popularization value.
