PROBLEM TO BE SOLVED: To enhance antioxidizing activity of aminocarbonyl compounds by inoculating a composition containing the aminocarbonyl compounds with a lactic acid facteria and culturing the resultant. SOLUTION: At least 3 wt.%, preferably 10-20 wt.% of amino compounds of a protein, an amino acid or the like are reacted with at least 2 wt.%, preferably 5-15 wt.% of reducing sugar or the like at a temperature of 100-121 deg.C for 7-90 min to prepare aminocarbonyl compounds of L-value 65-85. A lactic acid facteria of leuconostoc lactics, lactobacillus casei, lactobacillus rhamnosus, lactobacillus delbrueckii subspecies, bulgaricus or the like is inoculated on a composition containing the aminocarbonyl compounds and the resultant is cultured in the pH up to 4. Thus, antioxidizing activity of aminocarbonyl compounds can be enhanced without being required severe heat conditions. |
