Description
Technical field
The present invention relates to food processing technology field, more particularly to a kind of attapulgite modified preparation method and its removing
The application of aflatoxin, free fatty and phosphatide in edible oil.
Background technology
In the prior art, there is the impurity such as aflatoxin, free fatty in edible oil crude oil, be unfavorable for that human body is good for
Health, phosphatide can be denatured influence oil product local flavor and influence health therefore need to be taken off when edible oil is prepared in frying high temperature
Remove.
For the removal of free fatty, conventional method is addition alkaline aqueous solution, generally NaOH, potassium hydroxide
Or sodium bicarbonate solution, in making grease there is saponification and then reduce acid value of lipids in free fatty with alkali.But this soap
In change method, alkaline aqueous solution easily by the non-free fatty acid saponification in grease, with grease free fatty produce compared with
Big soap group, easily wraps up grease, and addition highly basic can bring dense alkali taste to grease, it is impossible to obtain meeting national standard
The grease of local flavor.For the removal of phosphatide, conventional technical means is addition water or the salt solution in crude oil so that hydrophily phosphatide
Water swelling, then filtering removal, but there is very big deficiency in the stability and local flavor of edible oil after addition water or salt solution, it is fragrant
The taste retention time is short.For aflatoxin, prior art needs to be removed by alkali, highly basic is added in edible oil crude oil molten
Liquid, aflatoxin can decompose with highly basic, and so as to reach removal effect, but the edible oil crude oil for the treatment of can not directly be eaten
With scent is dense and opaque.
The scheme of prior art can only remove one kind in AFB1, free fatty and phosphatide in edible oil
Or two kinds, it is impossible to it is enough to solve the problems, such as in edible oil that acid value high, AFB1 and content of phospholipid are high simultaneously.
The content of the invention
In view of this, it is an object of the invention to provide a kind of attapulgite modified preparation method, what is obtained is modified recessed
Convex rod soil is provided simultaneously with depickling, dephosphorization, the effect of de- AFB1 when for eating crude Treatment, meets national food
Product add the requirement of auxiliary agent, solve crude oil fragrance, acid value, AFB1, phosphating treatment present in prior art not
The problem that can be got both.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：
The present invention has put forward a kind of attapulgite modified preparation method, comprises the following steps：
(1) attapulgite clay is mixed with strong alkaline substance and water carry out it is alkalization modified, obtain alkalize attapulgite；
(2) the alkalization attapulgite roasting for obtaining the step (1), obtains attapulgite modified.
Preferably, the mass ratio of attapulgite clay, strong alkaline substance and water is 100 in the step (1):[0.5,1.2]:
1。
Preferably, the alkaline matter in the step (1) includes one or more in hydroxide and NaOH
Mixture.
Preferably, the pH value of the alkalization attapulgite for being obtained in the step (1) is 11~14.
Preferably, the temperature of roasting is 280~300 DEG C in the step (2), and the time of the roasting is 1~3h.
Preferably, also include after alkalization modified in the step (1)：The alkalization attapulgite compressing tablet that will be obtained, obtains piece
Shape firing precursor.
Preferably, the thickness of the sheet firing precursor is 0.5~1.5mm.
Preferably, also include after the roasting：It is milled after the product of roasting is cooled down.
Present invention also offers the preparation method described in above-mentioned technical proposal obtain it is attapulgite modified remove it is edible
The application of aflatoxin, free fatty and phosphatide in crude oil.
Preferably, the attapulgite modified mass ratio with edible crude oil is 1~3:100.
The invention provides a kind of attapulgite modified preparation method, attapulgite clay is mixed with strong alkaline substance and water
Conjunction carry out it is alkalization modified, obtain alkalize attapulgite, then will obtain alkalization attapulgite roasting, obtain attapulgite modified.
By the attapulgite clay that alkalizes, every small attapulgite is set to be alkalescence, the alkalization attapulgite of fired treatment makes concavo-convex
Rod soil is expanded, it is expanded after attapulgite have good liquid pass through property and the effect high with oily degree of mixing, so as to effectively drop
Low oil is damaged, and small neat soap can be produced after free fatty in alkaline attapulgite absorption edible oil crude oil, and neat soap is former to edible oil
Phosphatide in oil has suction-operated, simultaneously because neat soap belongs to alkaline matter, can decompose AFB1, reaches de-
Except the effect of AFB1.Therefore, it is attapulgite modified obtained in the present invention simultaneously to reach depickling, dephosphorization, de- Huang
The function of aspertoxin B1, the grease after attapulgite treatment modified by this invention directly reaches national standard, it is not necessary to refine
Technique.Embodiment effect shows that the attapulgite modified of addition 1% makes crude oil acid value reduction by 0.5~0.7, aflatoxin
B1 removals 95%, phosphatide reduction more than 100ppm, solve conventional method fragrance, acid value, AFB1 and phosphating treatment
The problem that can not be got both, and process is simple, it is not necessary to which cumbersome technique is that can reach Standard, reduce cost, do not influence oil
Fat mouthfeel, fragrance keeps long.
