Description
Technical field
The present invention relates to food processing technology fields, in particular to a kind of to remove vegetable protein using complexed surfactant
The method of Isoprothiolane and hexaconazole in powder.
Background technique
Not fully, rice blast is potential in Rice Production to demand of the different phase of paddy growth to disease control
One of dangerous most serious disease, the use of Isoprothiolane mainly appear on before jointing after leaflet latter stage and jointing cut to Qi Sui
Phase.Use the residual exceeded rice residue of the agricultures such as Isoprothiolane as rice protein raw material, directly makes the rice protein product being process
There are the residual exceeded harm of agriculture.GB 2763-2016 regulation Isoprothiolane content must not exceed 1ppm, and U.S. FDA provides China's export
Into the food in the U.S., Isoprothiolane content must not exceed 10ppb, therefore the method for developing removing Isoprothiolane is referred to as urgently to be solved
Problem.
Three kinds of Bio-surface actives removal Pesticide Residue in Soil residual such as Yang Huijuan, obtains preferable effect, using 20mL,
The 1:1 complexed surfactant (APG0810 and saponin) of 20g/L to six six six in soil, DDT, heptachlor, Acetochlor and
Cypermethrin maximum material removal rate is 40.31%~98.62%, but this method does not refer to the removal for Isoprothiolane and hexaconazole
Effect, while being not field of food technology.Huang wu is peaceful etc. to be disclosed hydrogen peroxide and ethyl alcohol under a kind of neutrallty condition and removes rice
The method of Isoprothiolane in albumen, by the hydrogen peroxide oxidation of 0.5-5%, 60% or more ethanol solution removes Isoprothiolane, wherein
Isoprothiolane removal rate reaches 90% or more, and Isoprothiolane residual quantity is lower than 10ppb, but 60% or more ethyl alcohol is used to remove rice
Pest spirit requires height there may be certain arrangement hidden danger and to production equipment, and whether following protein powder quality, which is affected, does not mention
And.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, it is de- using complexed surfactant that the applicant provides a kind of
Except the method for Isoprothiolane and hexaconazole in plant protein powder.The method of the present invention reaches the removal rate of Isoprothiolane and hexaconazole
90% or more, and albumen powder mouthfeel is not influenced.In addition, low to production equipment requirement, production cost is low.
Technical scheme is as follows:
A method of using Isoprothiolane and hexaconazole in complexed surfactant removing plant protein powder, this method includes
