Description
Technical field
The present invention relates to edible oil technical field, a kind of method that oily grape fruit oil prepares edible oil is specifically referred to.
Background technology
Oily vine has the names, scientific name idesia (Idesia Polycarpa such as wooden, the water wax gourd of the white red, Guar of bucket respectively
) and mutation Idesia polycarpa (IdesiaPolycarpa Var.vestita Giels) Maxin.It is that China is distinctive a kind of wild
Raw large-scale deciduous tree, distribution is wide, strong adaptability, hobby moistening fertile soil, but also drought-resistant barren, acid and neutral
It can be grown very well in soil.There is the custom of edible oil grapefruit in common people among the people.But because the oil has a strand strong bitter taste
And rancidity, it is among the people to this without effective means, fail to be widely used and promote for a long time.
Patent CN 102191128A《A kind of preparation method of edible idesia oil》Phosphoric acid or lemon are used in scouring processes
Lemon acid carries out vacuum dehydration (vacuum 4000-5000Pa), again lower after the completion of dehydration again as degumming agent after the completion of degumming
Vacuum degree condition under depickling (10-20Pa).The acidic materials that this method is used add environmental treatment cost, while this method
Use condition of high vacuum degree condition, equipment investment increase.Scouring processes can not ensure that degumming is clean, be unfavorable for bulk industrial production.
Patent CN 105861140A《A kind of Idesia polycarpa method for refining raw food oil》This method uses oxalic acid as degumming agent, de-
Carry out being filtered under diminished pressure after a depickling (alkali, which is neutralized, removes soap) is dried in vacuo again after the completion of glue, after being decolourized afterwards again
Deodorization processing is carried out once more after de- hardship, de- hardship are carried out with alcohol solvent.Complex process, and to be grasped under condition of high vacuum degree
Make, equipment requirement is high.Patent CN 103173283A《A kind of solvent acid stripping method of edible idesia oil》This method uses ethanol
Idesia crude oil is carried out after extraction heat, stratification, then solvent is removed with vacuum distillation.This method is only carried out to deacidifying process
Optimization, without complete food-grade technology.Above technology Shortcomings in use, reaction directly perceived exists on product
Pained and rancid peculiar smell is difficult to edible situation.
Pained and rancid peculiar smell of the technical problems to be solved by the invention aiming at oily grape (scientific name idesia) oil
It is difficult to edible situation and refines into the food plant for meeting state health standards there is provided a kind of processed from pretreatment of raw material to refining
The technology of oil and technological process.
The content of the invention
It is an object of the invention to provide a kind of method that oily grape fruit oil prepares edible oil, it is solution edible vegetable oil
There is provided a brand-new raw material variety, the edible vegetable oil produced using the present invention, which further can refine to be made, meets items
The polished fat of index.
To achieve these goals, present invention employs following technical scheme：A kind of oily grape fruit oil prepares edible
The method of oil, comprises the following steps：
1) pretreatment of raw material：Ripe oily grape fruit is harvested, the enzyme case that goes out is sent into after removing impurity and carries out the enzyme that goes out, so
Collected after the oily grape fruit after the enzyme that goes out is dried afterwards, storage needs the condition that shady and cool ventilation is dried；
2) raw material degumming process：By oily grape fruit, fruit carries out squeezing out crude oil entirely, will precipitate the crude oil after filtering and stirs
40 DEG C~75 DEG C are heated to, the water for then adding the same oil temperature of quality of crude oil 1%~7% is stirred 10~60 minutes, precipitation 3~10
Hour；
3) the de- bitter, processing of taking away the puckery taste of crude oil：Alkali lye is added after crude oil temperature after degumming is adjusted into 10 DEG C~50 DEG C, is stirred
10~60 minutes, while oil temperature is risen into 40 DEG C~90 DEG C, staticly settle 4~10 hours；
4) crude oil washing, detection process：Crude oil after de- hardship is taken away the puckery taste is heated to 50 DEG C~100 DEG C, adds oil quality 5%
~30% with oil temperature soft water wash 2~3 times, make water-oil separating；The acid number of test oil is less than 3, in the water separated
Instill after detection liquid without discoloration；
5) dewater treatment：The oil for detecting qualified is heated to 90 DEG C~150 DEG C.Add food-grade water removal auxiliary agent.
Further, described crude oil is the full fruit oil of oily grape fruit.
Further, described alkali lye is NaOH or Na2CO3Or other possible alkali lye.
Further, described detection liquid is FeCl3。
Further, described food-grade water removal auxiliary agent is non-ionic surface active auxiliary agent, such as sorbester p18.
The beneficial effects of the present invention are：It is edible to solve there is provided a kind of preparation method of brand-new edible vegetable oil
Vegetable oil provides a brand-new raw material variety, and the edible vegetable oil produced using the present invention, which can be refined further, is made symbol
Close the polished fat of indices.
