AI Technical Summary

Technical Problem

Existing mineral-fortified formulations, particularly those based on proteins, are prone to coagulation or precipitation during heat treatment, making them unsuitable for liquid applications and affecting the stability and solubility of iron and other minerals.

Method used

The formation of soluble mineral complexes through unheated or heated mixtures of proteins and carbohydrates, with pH adjustments and Maillard Reaction Products (MRPs), to enhance solubility and stability, using buffering agents like phosphates and citrates to modulate pH and complex formation.

Benefits of technology

The method produces stable and soluble mineral complexes that can withstand heat processing, improving the delivery and bioavailability of minerals like iron, while preventing precipitation and maintaining clarity in liquid formulations.

Abstract

A mineral supplement or fortified food ingredient product comprising nutritional minerals and unheated protein-carbohydrate carriers or Maillard Reaction Products (MRP) produced by heating aqueous protein-carbohydrate mixtures. The components in the formulation comprise protein, carbohydrates, mineral(s) iron salts / chelates and pH modifying agents. The product may also be a mixture of complexed iron compounds that is stable to heating. The protein complexed with iron may exist as soluble colloidal dispersion of iron-protein entities. A dried formulation of the nutritional mineral supplement may be obtained by dehydration of the aqueous mixture. The wet or dried product may be used in supplements or added to foods to obtain mineral-fortified foods.
