Protein nutritional value, polyphenols and antioxidant properties of corn fermented with Agaricus brasiliensis and Agaricus bisporus

Solid-state fermentation (SSF) with Agaricus brasiliensis and Agaricus bisporus on corn was carried out. The results showed that SSF with the two fungi made up the deficiency of tryptophan in corn and improved the protein nutritional value of corn. The conjugated polyphenols contents in fermented corn decreased and free polyphenols (FPP) contents increased. FPP contents in corn fermented with the two fungi reached respectively 25 and 88 times of control, total polyohenols contents reached respectively 1.4 and 3.3 times of control. The antioxidant properties (i.e. 1,1-diphenyl-2-picrylhydrazyl radical scavenging capacity, reducing power, ferrous ion chelating ability and superoxide anion radical scavenging ability) of fermented corn were improved significantly. SSF with A. bisporus was more favorable to the enhancement in protein nutritional value and antioxidant properties of corn than that of A. brasiliensis. The results indicated that SSF with the two fungi could upgrade the protein nutritional value, FPP content and antioxidant properties of corn.
