Composite edible salt anti-caking agent and preparation method thereof

Abstract

The invention discloses a composite edible salt anti-caking agent and a preparation method thereof. The composite edible salt anti-caking agent is prepared from silicon dioxide, magnesium carbonate and tricalcium phosphate; the weight percent of the silicon dioxide, the magnesium carbonate and the tricalcium phosphate in the total weight of the anti-caking agent is 0.01 to 5.0 percent; and a particle size range of the silicon dioxide, magnesium carbonate and tricalcium phosphate is 0.005 to 5.00 meshes, and a weight ratio of the anti-caking agent to edible salt is 0.05 to 9.0 percent. By adopting the composite edible salt anti-caking agent and the preparation method thereof, a novel choice is provided for the edible salt enterprises in China to solve the novel and safe anti-caking agent without hidden dangers, and the psychological panic of people caused by the food safety problem of the traditional edible salt anti-caking agent can be solved.

Description

technical field

[0001] The invention belongs to the technical field of food additives, in particular to a compound edible salt anticaking agent and a preparation method thereof. Background technique

[0002] At present, the anticoagulants allowed to be used in table salt in my country mainly include potassium ferrocyanide, tricalcium phosphate, ammonium citrate, calcium silicate, amorphous silica, sodium aluminosilicate, magnesium carbonate, microcrystalline cellulose, etc. , but because potassium ferrocyanide has an impact on the absorption of mineral elements by the human body, the permeability of ion membranes in industrial production and the export of some salt products. In the document "Zhang Guangwen, Dai Xiaoming, Xu Jing. Feasibility Discussion on Two Anticaking Agents Used in Salt Anticaking. Suyan Science and Technology. 2010 (3)." Two anti-caking agents were used to explore their anti-caking properties. This study clearly compared the anti-caking effects of the tw...

[0018] The preparation method of the composite edible salt anticaking agent provided by the embodiment of the present invention comprises the following steps:

[0019] Step 1. Measuring the particle size of edible salt respectively by microscope method: after the eyepiece micrometer is calibrated, measure the original salt slide of the prepared sample with a microscope respectively, and calculate the particle size;

[0020] Step 2. Selection of an anticaking agent that matches the particle size of table salt. The whiteness is close to that of table salt, and the particle size is close to that of salt crystals. Therefore, silicon dioxide, magnesium carbonate, and tricalcium phosphate with a particle size of 0.01-3.00 mesh are selected as the compound Type edible salt anticaking agent component;

[0021] Step 3. Single factor test: take 500g of raw salt as the unit sample, add the three anti-caking agents in equal gradients within the maximum usage range, mix evenly, pack the ba...

Embodiment 1

[0025] Embodiment 1: Microscopic measurement, well salt salt crystal grain size.

[0026]The first step: inspection and preparation before using the microscope. Put the eyepiece micrometer into the selected eyepiece, install the eyepiece and objective lens on the microscope, put the standard micrometer (10 μm per grid) on the stage, and adjust the focal length by rotating the public drop screw to calibrate the eyepiece micrometer The length represented by one grid ratio (μm);

[0027] Step 2: Calibration of the eyepiece micrometer. First observe with a low power lens, align the focal length, see the scale of the objective lens micrometer clearly, then turn the eyepiece so that the scale of the eyepiece micrometer is parallel to the scale of the objective lens micrometer, and coincide with the first line on the left side of two feet, Then look for another coincidence line two feet to the right, and record the number of divisions of the eyepiece micrometer and the number of di...

[0033] Example 2: Single factor test of silicon dioxide Determination of its anti-caking performance to mine salt.

[0034] Step 1: Weigh 500g of raw salt one by one with an electronic balance, and pack them in transparent food plastic bags;

[0035] The second step: use an analytical balance to add silicon dioxide according to the mass of the original salt within the maximum usage range of 50g / kg, so that the sample has a gradient concentration;

[0036] The third step: Add the original salt sample and the single anticaking agent mixture according to the ratio of 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, 4.5%, 5.0%, and mix evenly, exhaust Finally, the plastic bag is sealed and labeled, and placed in a biological incubator (simulated environment, but the humidity is greater than the ambient humidity) with temperature, humidity and pressure stable at room temperature and local atmospheric pressure conditions;

[0037] Step 4: After observing the first agglomeration, wei...
