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.
