The product on the basis of ferrous sulphate for the fortification of dried foods and methods of preparation

摘要

"Product based on ferrous sulphate for the fortification of dried foods and preparation method.This patent refers to a product, a source of iron for use as a valuable food, which maintains its sensory properties are stable during storage.Obtained from the formation of a layer of alginate on particles of bioavailable iron salts, in particular of ferrous sulfate, and the method of preparation.The present invention provides a way to modify bioavailable iron salts, in particular of ferrous sulfate monohydrate (FeSO4 H2O). ~ 4 ~.H ~ 2 ~) to circumvent problems with its use in food, and particularly in flour of wheat and other cereals and prepared foods like bread, noodles and cakes.With the innovation of coating the particles with alginate.A natural polysaccharide extracted from algae, which presents a great facility for gel formation with divalent metal ions such as Ca ^ + 2 ^ or Fe ^ + 2 ^, among others.The preparation method consists firstly in the deposition of a film of sodium or potassium alginate on the surface of particles of ferrous sulfate or a salt of the bioavailable iron.Followed by successive steps of drying,The deposition or not of a film policu00e1tions or synthetic polymer and drying and deposition of a new layer of alginate and drying until it reaches the coating and particle size desired.
