Abstract

The purpose of this research was to analyze carotenoid content, anthocyanin content, phenolic compound content and the antioxidant activity by 2, 2-diphenyl-1-picrylhydrazyl scavenging capacity (DPPH) and 1, 10-Phenantroline (Phen). In the 3 varieties of corn milk which were the Queen Ruby Siam strain (Purple corn milk), (White corn milk), Sweet strain (Yellow corn milk). It was found that the samples of 3 types of corn milk have total carotenoid content were 0.45+0.00 0.29+0.02 and 0.68+0.00mg/l respectively. Anthocyanin content measured by pH-differential method were 2.86+0.01 1.71+0.03 and 0.80+0.01 mg/l respectively. The total amount of phenolic compounds were 12.00+0.02 10.05+0.00 and 8.62+0.09 mg/l respectively. The ability to resist free radicals by DPPH method were equal to 96.50+0.10  47.10+0.01 and 60.91+0.08 respectively. The antioxidant activity using Phen method were 133.98+0.76  111.17+0.48 and 86.61+0.98 mg/l respectively.
