PROBLEM TO BE SOLVED: To provide a new method for depressing the reaction of vitamin C.SOLUTION: This method for depressing the reaction of vitamin C includes covering vitamin C with calcium, and also using a binder for binding vitamin C and calcium. The 50% particle diameter (median diameter) of vitamin C is ≥50 and ≤500 μm, and preferably, ≥100 and ≤400 μm. The 50% particle diameter (median diameter) of calcium is ≥0.1 and ≤80 μm, and preferably, ≥5 and ≤30 μm. |
