Description
Technical field
The present invention relates to a kind of methods of degumming of rape oil, belong to food processing technology field.
Background technique
Rape is one of big oil crops in the world four, is mainly used for edible fat production.Rapeseed oil Linoleic acid and linolenic acid
Rich content, degree of unsaturation is higher, has unique fragrance, and rich in a variety of work such as phosphatide, polyphenol, sterol, carrotene
Property ingredient.Although the phosphatide in rapeseed oil has the effects that adjust body metabolism, builds up health, relieves fatigue, oil and fat refining
What remaining phosphatide may cause rapeseed oil in the process returns color and aftertaste, it is therefore desirable to remove, reduce in oil and fat refining process
Or the technique of removal phospholipid in lipid is known as degumming technology.
Traditional Degumming method mainly has aquation degumming, absorption degumming and enzymatic degumming.Absorption degumming need up to 3h~
The time of repose of 8h；When carrying out enzymatic degumming using phosphatidase, the enzyme digestion reaction time is long, generally requires 3h~5h, which can increase
The acid value for adding degummed oil, it is unfavorable to subsequent deacidifying process.In addition, enzymatic degumming higher cost.Currently, aquation degumming is still
The main Degumming method of fats and oils processing enterprise.Cost is relatively low for aquation degumming, but degumming effect is not ideal enough, it would be highly desirable to develop one kind
The good rapeseed oil aquation Degumming method of short processing time, degumming effect.
In recent years, ultrasonic technology food, medicine, chemical field using more and more extensive.Ultrasound cavitation effect produces
Raw cavitation bubble increases interfacial area in the rupture of immiscible two phase boundray；And cavitation bubble ruptures to be formed micro- and penetrates
Stream can generate strong stirring action to solution, increase the mass-transfer efficiency of solution.Therefore, ultrasonic wave rapeseed oil aquation is used to take off
Glue process is to improving the degumming effect of rapeseed oil.
Summary of the invention
Degumming is inefficient when the purpose of the invention is to overcome the shortcomings of traditional crude rapeseed oil aquation degumming, improves one
The method of kind ultrasonic wave added degumming of rape oil.
The technical solution adopted by the invention is as follows:
A kind of method of ultrasonic wave added degumming of rape oil carries out as steps described below:
(1) crude rapeseed oil is weighed, is heated to 40 DEG C~80 DEG C, weighs the citric acid that mass ratio is 0.05%~0.35%,
And the distilled water of mass ratio 1.5%~4.0% is measured, citric acid and distilled water are mixed and dissolved, citric acid solution is heated
To crude oil it is mutually synthermal after make an addition in crude oil, stirring make crude rapeseed oil aquation 10min~60min；(2) using frequency 40kHz,
Ultrasonication 10min~30min of power 150W is centrifuged (4800r/min, 20min) after being stored at room temperature 5min；It (3) will be upper
Layer oil reservoir rotary evaporation under the conditions of 0.09Mpa, 70 DEG C removes moisture；(4) according to GB/T5537-2008 " grain and oil detection phosphatide
The measurement of content " phosphorus detection is carried out, and calculate degumming rate.
The present invention assists crude rapeseed oil degumming using ultrasonic wave, can greatly improve degumming efficiency.
