The technical difficulties caused by the manufacture of infant milk powder are much higher than those encountered in the production of other dairy products for common consumption.

Good sanitary practices

To obtain the microbiological characteristics required for the product, quality management is very important :

  • Stringent sanitary conditions must be established and adhered at the place of manufacture
  • More generally, the entire manufacturing process must be designed or modified to reflect this requirement.

 

The delicate step of spray drying

The complexity of the formulations induce the complexity of drying operations.
In fact, each different formula requires different drying parameters; any change, addition or subtraction of ingredients challenges the parameter settings, which must then be completely redefined.

It is through empirical tests, lengthy and expensive, that most dairy companies determine the drying parameters. To evade from  this complexity, many manufacturers dry some aggregated ingredients, then mix them in the dry phase. However, only the liquid phase mixture, followed by drying under controlled conditions of the complete formulation, ensures consistency and quality in the reconstitution of the feeding bottle.

 

Processes respecting product integrity

The industrialists, actuated by the defense of infant well-being, but also pushed by more stringent legislative standards, need to develop and promote transformation processes (heat treatment, oxidation ...) that preserve all the nutritional quality(link to page 19) of their infant formula milk.

With its dedicated expertise (link to page 25), LISA aims to open, for the interested companies, access to such a highly technical production of infant milk.
