Problems solved by technology

[0003] Ferric pyrophosphate is often added to food as fortified iron due to its wide application range and high safety. Oxidation-reduction reaction occurs, resulting in black precipitation, which not only affects the appearance of food, but also has adverse effects on dietary health; and the fluidity of ordinary ferric pyrophosphate is poor (powder-like electrostatic adsorption produces clumping phenomenon), which also affects processing performance

Embodiment 1

[0018] Example 1 Preparation of ferric pyrophosphate powder added to vitamin-containing foods

[0019] First, the commercially available ferric pyrophosphate raw material is ultrafinely pulverized to form an ultrafine powder of about 10 μm for use;

[0020] Put 100Kg of ultra-finely pulverized iron pyrophosphate powder, 20Kg of polyacrylic acid resin III, 70Kg of sodium starch octenyl succinate, and 10Kg of calcium gluconate in 1000Kg of purified water, stir to form a suspension, and then use a 2-ton preparation tank Perform high-speed shearing and homogenization (for 55-60 minutes) at a speed of 20-25 rpm, and finally send the emulsion into the spray drying tower for spray drying, keep the inlet air temperature of the spray drying tower at 180 °C, The wind temperature is 90°C, and the spray-dried powder is sieved through 80 mesh, weighed and packaged for storage.

[0021] When used as a food fortifier, it should be added at 10% of the total weight of the material, and evenly...

Embodiment 2

[0022] Example 2 Preparation of ferric pyrophosphate powder added to vitamin-containing foods

[0023] Similarly, the commercially available ferric pyrophosphate raw material is ultrafinely pulverized to form an ultrafine powder of about 10 μm for use;

[0024] Put 150Kg of ultra-finely pulverized iron pyrophosphate powder, 25Kg of polyacrylic acid resin III, 70Kg of sodium starch octenyl succinate, 5Kg of calcium gluconate into 1000Kg of purified water, stir evenly to form a suspension, and then use a 2-ton preparation tank Perform high-speed shearing and homogenization (for 55-60 minutes) at a speed of 20~25 rpm, and finally send the emulsion into the spray drying tower for spray drying, keep the inlet air temperature of the spray drying tower at 170 °C, The air temperature is 85°C, and the spray-dried powder is sieved through 100 mesh, weighed and packaged for storage.

[0025] When used as a food fortifier, it should be added at 10% of the total weight of the material, an...

Embodiment 3

[0026] Embodiment 3 The performance comparison of ferric pyrophosphate produced by the present invention and commercially available ferric pyrophosphate

[0027] Common commercially available ferric pyrophosphate and the finished powder of ferric pyrophosphate produced in Example 1 of the present invention were mixed with vitamin C in the same proportion, and then the brewing experiment was carried out. The result is as figure 1 shown.

[0028] figure 1 The picture on the left in the center shows the solution prepared by vitamin C containing conventional ferric pyrophosphate, and the black precipitate produced after the reaction can be clearly shown in the picture; After adjusting the solution, it can be seen that the solution is clear and no black precipitate is produced.

[0029] The ferric pyrophosphate produced by the present invention is added in vitamin-containing nutritious food as an iron-fortified element, and the iron content in the solution is measured after weig...

Abstract

The invention discloses a production method of ferric pyrophosphate to be added into foods containing vitamins. The production method of the ferric pyrophosphate to be added into the foods containingthe vitamins comprises the following steps: performing ultrafine crushing on a commercially available ferric pyrophosphate raw-material; adding water, polyacrylic resin III, starch sodium octenyl succinate and calcium gluconate in proportion so as to obtain a suspension by performing blending, and adjusting the pH value of the suspension to 6.0-8.0; and then, performing high-speed shearing and homogenizing on the blended suspension, and carrying out spray-drying so as to obtain a finished ferric pyrophosphate powder product. The production method of the ferric pyrophosphate to be added into the foods containing the vitamins has the following advantages: carbohydrates are used as a wall material so as to perform embedding treatment on a common ferric pyrophosphate raw-material by adopting amicroencapsulation technology, so that, the treated ferric pyrophosphate has good fluidity; and thus, processing performance of the ferric pyrophosphate is improved. Therefore, being used in the foods containing the vitamins as an iron fortifier, reaction between the treated ferric pyrophosphate and the vitamins can be avoided; and thus, no black precipitate is produced during brewing process. The foods added with the ferric pyrophosphate are good in taste and healthier for drinking.

Description

technical field [0001] The invention relates to an iron salt for food addition, in particular to a method for producing iron pyrophosphate added to vitamin-containing foods. Background technique [0002] Iron is one of the essential trace elements for the human body. Although its content in the human body is low, it is the main component of human hemoglobin, and is closely related to the human body's immune system. It plays a vital role in the physiological activities of the human body. Therefore, the human body cannot lack iron. For iron supplementation, in addition to dietary intake, you can also take some nutritional foods that fortify iron. [0003] Ferric pyrophosphate is often added to food as fortified iron due to its wide application range and high safety. Oxidation-reduction reactions occur, resulting in black precipitation, which not only affects the appearance of food, but also has adverse effects on dietary health; and ordinary ferric pyrophosphate has poor flu...
