In this study, 64 cases of fruit and vegetable beverages were investigated for vitamin C, polyphenol, and mineral contents. The results showed that vitamin C content ranged from 1.851 to 251.108 mg/100 mL, and the mean content was highest in non-heated apple juice at 89.646 mg/100 mL. Polyphenol content ranged from 260.767 to 1895.095 mg gallic acid equivalent (GAE)/L, and the mean content was also highest in non-heated apple juice at 1042.311 mg GAE/L. Selenium and copper contents were highest in heated orange juice at 0.101 and 22.875 µg/100 mL, respectively. Magnesium, phosphorus, and iron were highest in the non-heated strawberry juice at 4.281, 16.085, and 0.400 mg/100 mL. Zinc was highest in heated strawberry juice at 149.344 µg/100 mL. Compared to the recommended daily intake for adult men, vitamin C could be consumed up to five times the recommended daily intake of 200 mL of juice, and more than 50% of the iron intake could be satisfied.
