Abstract
The invention relates to the field of edible oils and fats, in particular to maize oil containing vitamin A and vitamin E and a preparation method thereof. The vitamin AE maize oil contains the vitamin A and the vitamin E, so that the maize oil simultaneously meets double requirements of people on the vitamin A and the vitamin E. The maize oil contains over 65 percent of linoleic acid and rich phytosterol, so that the maize oil can provide sufficient nutrient substances for all using crowds; and the maize oil product being prepared by the method and containing the vitamin A and the vitamin E is oily liquid, is light yellow in color, has good mouthfeel, and meets the production requirement.
Description
Technical field
The present invention relates to the edible oil and fat field, relate in particular to a kind of corn oil that contains vitamin A, vitamin E and preparation method thereof.
Background technology
Vitamin A is to constitute the constituent of experiencing the rhodopsin of the low light level in the cellula visualis.Rhodopsin is made up of opsin and 11 – Shun – retinenes, and is relevant with noctovision, and it has the effect of epithelial tissues such as protection skin or firewood film, and vitamin A is that human body is necessary, but human body itself can not synthesize the nutrient of (relying on food entirely provides) again.Vitamin E is one group of liposoluble vitamin, claims tocopherol again, comprises tocopherols, triolefin tocopherols.Anti-oxidation function is all arranged, and is one of topmost anti-oxidant.For the animal normal growth essential with fertility institute.
Protect vitamin A with natural VE as anti-oxidant; The relation of vitamin E and vitamin A is also very close simultaneously; Vitamin E not only can be protected the vitamin A in the edible oil; And can prevent the oxidation of vitamin A in the enteron aisle and promote absorption, can improve vitamin A storage capacity in vivo simultaneously.In addition, vitamin E has removes free radical activity preferably, reduces cell senescence, keeps erythrocytic integrality, promotes the synthetic of cell, the effect of antipollution, antisterility.
Developing the demand that the grease with specific function satisfies consumers in general at present, is the developing direction of present oils industry.Corn oil is claimed maize germ oil again, is a kind of high-quality edible vegetable oil, contains unrighted acid and abundant phytosterol more than 80% in the corn oil.Must not be according to Chinese Soclety of Nutrition's recommendation vitamin E intake every day above 30 milligrams; With 20～30 milligrams of every days be the best; The oil quantity that the expert advice adult absorbs for each person every day is 25～30 grams; Develop and a kind ofly can satisfy people's demand, the corn oil that contains vitamin A and vitamin E is one of emphasis problem of grease production business research.
Summary of the invention
The object of the invention is exactly to the defective of above-mentioned existence a kind of corn oil that contains vitamin A, vitamin E and preparation method thereof to be provided.Contain vitamin A, vitamin E in the vitamin ae corn oil of the present invention, satisfied the dual requirements of people simultaneously for vitamin A and vitamin E.Also contain linoleic acid more than 65%, and the above phytosterol of 500mg/100g in the corn oil; Can be all use crowds the prescribing adequate nutrition material is provided; Adopting the prepared corn oil product that contains vitamin A, vitamin E of method of the present invention is oily liquids; Be faint yellow, mouthfeel is good, the accords with production requirement.
A kind of vitamin ae corn oil technical scheme of the present invention does; Contain vitamin A, vitamin E in the said corn oil; Percentage comprises following each component by weight: the vitamin A addition is 0.0004%-0.0008%, and the vitamin E addition is 0.010%-0.018%, and all the other are corn oil.
A kind of preparation method of vitamin ae corn oil comprises following processing step:
(1) pre-treatment of raw material
Soyabean deodorization distillate mixes with methyl alcohol by a certain percentage, uses the sulphuric acid catalysis esterification, and through washing, the material after the washing is that catalyst carries out alcoholysis with the sodium methoxide again, removes the part phytosterol through cold analysis again;
(2) separation and purification of vitamin E
The a soyabean deodorization distillate gets into the thin film evaporator evaporation through being preheated to after the pre-treatment about 100-120 ℃, and evaporation back material gets into thin film evaporator once more after preheating, and pressure is controlled at 0.25MPa, and evaporation back material gets into first order molecular still through preheating again;
Get into second level molecular still after the heavy ends preheating of b upper level distillation; Cloth, knifing, evaporation, condensation in molecular still equally; Purpose product vitamin E just separates with heavy ends, feed rate 1.0 mL/min, blade applicator rotor speed 120r/min;
(3) will be by weight percentage comprise following each component: vitamin A 0.0004%-0.0008%, vitamin E 0.010%-0.018%, all the other are corn oil, under nitrogen protection, after stirring with 20-50 rev/min, quantitative package.
Described preheater of a and molecular clock all adopt heat-conducting oil heating in the step (2), and the temperature control of conduction oil oil is at 120-130 ℃, and the system vacuum degree is 1-2Pa, 35-45 ℃ of circulation warm water of cold true employing in the molecular clock.
Described preheater of b and molecular clock also are to adopt heat-conducting oil heating in the step (2), and the temperature control of conduction oil oil is at 200-220 ℃, and the system vacuum degree is 1-2Pa, cold true 35-45 ℃ the circulation warm water that also adopts in the molecular clock.
Product of the present invention is an oily liquids, because these article are the nutrition and health care grease, manner of packing is taked inner wrapping usually, and its packing specification form has 1L, 2.5L, 3.6L, 5L, makes things convenient for family to use, and color is pure, and mouthfeel is good, and cooking is cold and dressed with sauce all can.
Beneficial effect of the present invention is: contain vitamin A, vitamin E in the vitamin ae corn oil of the present invention, satisfied the dual requirements of people for vitamin A and vitamin E simultaneously.Also contain linoleic acid more than 65%, and the above phytosterol of 500mg/100g in the corn oil, can be all use crowds the prescribing adequate nutrition material is provided.The corn oil product that contains vitamin A, vitamin E that the inventive method is prepared is an oily liquids, is faint yellow, and mouthfeel is good; Accords with production requirement, the vitamin E among the present invention are to be to handle with advanced molecular distillation technique in the aliphatic acid to make from soyabean deodorization distillate, realize natural VE product and more macromolecular separation such as neutral oil and pigment; Operating temperature is low, and heated time is short, has avoided chemical contamination; Thereby obtained keeping the VE product of pure natural characteristics, safely and effectively.Vitamin ae corn oil of the present invention is raw material with 100% maize germ oil, adopts physical refining process, has kept original vitamin E in the corn oil to greatest extent.Simultaneously; Regulation according to vitamin E addition in the national standard nutrition fortifier; Add a certain amount of vitamin E, can protect the multiple unrighted acid in vitamin A and the corn oil not oxidized on the one hand, vitamin A can better be absorbed by human body.
