Abstract


Beta-carotene is the most prominent member of the group of carotenoids, natural colorants that occur in the human diet.
Beta-carotene is also an effective source of vitamin A in both conventional foods and vitamin supplements, and it’s generally safe. In this study, we explored the beta-carotene contents in agricultural products widely and specifically grown in Korea. The beta-carotene contents were ranging from 223 to 27,908 μg/100 g in leaves, and 0 to 7,588 μg/100 g in vegetables. In leaves and vegetables, the amount of beta-carotene was the highest in green tea powder (27,908 μg/100 g), followed by pepper (7,588 μg/100 g). In fruits, the beta-carotene content was found to range from 0 μg/1,011 g to maximum of 293.66 μg/100 g(plumcot). However, there beta-carotene was not detected in strawberry. In the case of cereals and specialty crops, the beta-carotene contents were 326 μg/100 g for non-glutinous rice, 313 μg/100 g for glutinous rice, 57 μg/100 g for amaranth and 15 μg/100 g for pine nut, respectively. However, the beta-carotene content was not detected in other samples. This study revealed the presence of beta-carotene content in agricultural products specifically grown in Korea for nutritional information and food composition database.
