|
The content of β-carotene in agricultural foods, such as seasonings, tea, vegetables, cereals, nuts & seeds, oils & fats, and fruits, were quantitatively analyzed using reversed-phase HPLC with an UV/visible detector. Standard reference material (SRM) 2385 was used as a control material to validate measurement of β-carotene in this study. Recovery percentage and relative standard deviation of β-carotene in SRM 2385 were 102% and 1.73%, respectively. Vegetables and tea contained relatively high concentrations of β-carotene (young barley powder, 17,293.95 μg/100 g; raw young barley, 2,755.15 μg/100 g; dried green tea leaves, 13,671.85 μg/100 g; green tea powder, 7,579.04 μg/100 g). Contents of β-carotene in nuts & seeds as well as oils & fats ranged from 11.32 μg/100 g in almond products (roasted with salt) to 58.56 μg/100 g in perilla seed oil. Among 20 fruits, a high content of β-carotene was found in apricots (raw), which contained 2,280.35 μg/100 g.
