Magnesium chelation of low molecular weight peptides from protein-rich industrial wastes: Production and properties.

ABSTRACT: Magnesium chelating is considered a promising method to increase Mg uptake, thus fight against the prevalent case of Mg deficiency. In this study, hydrolysates and peptide fractions from spent brewer's yeast (SBY) and soybean meal (SBM) were evaluated for the magnesium chelating ability. Despite the similar amino acid profile and protein concentration, SBY hydrolysate showed superior chelating yield than that of SBM. Cross flow filtration was shown to have facilitated the chelating process, with the specific chelating yield peaked at 94.44 mg/g protein for the 3 kDa peptide fraction of SBY hydrolysate. It was also demonstrated that at optimum conditions (pH 2 to 4 and Mg loaded 5 mM to 25 mM), the ≤ 3 kDa peptide fraction of SBY exhibited the highest magnesium chelating yield of more than
