Compound anti-caking agent used in salt

Abstract

The invention discloses a compound anti-caking agent used in salt. The anti-caking agent is prepared by the raw materials including 70% of ferric citrate, 29% of tricalcium phosphate and 1% of calciumstearate by the following method: first weighing the ferric citrate and adding water based on 1% of the total weight of the three raw materials to stir the calcium stearate evenly, then adding the tricalcium phosphate and the calcium stearate, evenly stirring and drying the mixture, and grinding to prepare the anti-caking agent. Salt caking can be prevented by adding the compound anti-caking agent according to 0.0025% of the weight of the salt. An addition method comprises the following steps: weighing the salt and the compound anti-caking agent by proportioning, drying and then grinding thetwo substances, and directly mixing the two substances evenly by a mechanical method. The anti-caking agent has the advantages as follows: the three raw materials are nontoxic and harmless; the anti-caking agent can not generate harmful substances at high temperature; and tests show that the anti-caking effect of the anti-caking agent used in the salt is on a par with that of the conventional anti-caking agent potassium ferrocyanide.

Description

technical field [0001] The invention relates to an anticaking agent, in particular to a composite anticaking agent used in table salt. Background technique [0002] Now the anti-caking agent commonly used in domestic salt is potassium ferrocyanide, the product is relatively single, and the raw material is relatively safe within 200 °C, if the temperature is too high, it may produce toxic substances, endangering life safety, but in our When processing fried and grilled food, the temperature often exceeds 200°C, and long-term consumption will bring potential harm to our daily life. Contents of the invention [0003] The object of the present invention is to provide a composite anti-caking agent that does not contain cyanide, is non-toxic, harmless and has good anti-caking effect and is used in table salt. [0004] To achieve the above object, the present invention can take the following technical solutions: [0005] The composite anticaking agent used in table salt accordi...
