Embodiment 1

[0019] Add 100Kg of ultra-finely pulverized ferric pyrophosphate, 15Kg of sodium alginate, 5Kg of glyceryl monostearate, and 0.5Kg of enzymatically hydrolyzed soybean lecithin into 400Kg of purified water above 80°C to form a suspension, which is subjected to high-speed shearing and homogenization; The emulsion is spray-dried, the inlet air temperature is 170°C, and the outlet air temperature is 85°C. The spray-dried powder is sieved through 100 mesh.

[0020] Ordinary ferric pyrophosphate and the improved ferric pyrophosphate of this embodiment were formulated into 10% solutions respectively, put into a 100ml measuring cylinder, and left to stand for 24 hours, and the height of the interface between the supernatant and the colored part produced by the precipitation was judged visually. The results are shown in Table 1.

Embodiment 2

[0022] Add 200Kg of undried ferric pyrophosphate wet material, 20Kg of sodium alginate, 6Kg of glyceryl monostearate, 0.8Kg of enzymatically hydrolyzed soybean lecithin into 400Kg of purified water above 80°C to make a suspension, and adjust the pH range to 2.0 ~5.0, after high-speed shearing and homogenization; the emulsion is spray-dried, the inlet air temperature is 170°C, the outlet air temperature is 85°C, and the spray-dried powder is sieved through 100 mesh.

[0023] Ordinary ferric pyrophosphate and the improved ferric pyrophosphate of this embodiment were formulated into 10% solutions respectively, put into a 100ml measuring cylinder, and left to stand for 24 hours, and the height of the interface between the supernatant and the colored part produced by the precipitation was judged visually. The results are shown in Table 1.

Abstract

The invention discloses a production method of suspended ferric pyrophosphate, and relates to the technical field of ferric pyrophosphate production. According to the production method of the suspended ferric pyrophosphate, emulsifying-modifying treatments are performed on common ferric pyrophosphate by adopting a micro-encapsulation technology. The production method of the suspended ferric pyrophosphate specifically comprises the following steps: (1), blending superfine ground common ferric pyrophosphate or an undried wet common ferric pyrophosphate material with sodium alginate, glycerol monostearate and enzymatically hydrolyzed soybean lecithin so as to obtain a suspension of which the temperature is 80 DEG C or higher, and carrying out high-speed shearing and homogenization so as to obtain a mixed emulsion by performing emulsification; and (2), performing spray-drying on the emulsion, wherein the air inlet temperature is 160-190 DEG C and the air outlet temperature is 80-95 DEG C, and then, sieving the spray-dried powder so as to obtain a target product. According to the production method of the suspended ferric pyrophosphate, the emulsifying-modifying treatments are performed on the common ferric pyrophosphate by adopting a micro-encapsulation method comprising emulsifying, homogenizing and spray-drying so that the prepared suspended ferric pyrophosphate can be used as an iron element fortifier for beverages which produces no precipitates; moreover, the suspended ferric pyrophosphate is convenient for storage and transportation so that processing performances of the suspended ferric pyrophosphate in beverage-type foods are greatly improved.

Description

technical field [0001] The invention relates to the technical field of ferric pyrophosphate production, in particular to a production method of suspended ferric pyrophosphate. Background technique [0002] Iron is one of the essential trace elements in the human body. Although its content in the human body is low, it plays a vital role in the physiological activities of the human body. For example, it is the main component of human hemoglobin. They are closely related to each other, so the human body cannot lack iron; to supplement iron, in addition to dietary intake, you can also eat some nutritious foods that fortify iron. [0003] Soluble iron salts are used in beverages and foods, which have an iron smell that affects the taste. Iron pyrophosphate is widely used in food additives because it does not contain iron smell. It is suitable for flour, biscuits, bread, dry mixed milk powder, rice flour, soybeans Milk powder and other products; in foreign countries, it is also u...
