Carotenoids accumulate a lot in fruits that are orange, yellow, and red and green as antioxidants, help boost immunity, the objective of this research was to determine the total carotenoid content in 8 types of fruit as follows: Papaya (Carica papyya L.) Grape (Vitis vinifera L.) Jackfruit (Artocarpus heterophyllus Lam.) Pineapple (Ananas comosus) Banana (Musasapientum L.), Tomato (Solanum lycopersicum L.), Apple (Malus domestica), and watermelon (Citrullus lanatus) by acetone extraction method and the absorbance was measured with a spectrophotometer. The total carotenoid content was 1681.07 ± 0.00, 1230.83 ± 21.15, 1365.59 ± 6.59, 404.65 ± 2.85, 1222.35 ± 7.75, 1213.15 ± 3.71, 857.89 ± 0.0 and 936.01 ± 9.25 mg/L respectively. The highest total carotenoid content was papaya (Carica papyya L.) total carotene content 1681.07 ± 0.00 mg/L and the lowest content was pineapple containing carotene. Total carotenoids 404.65 ± 2.85 mg/L. The results of this research should be beneficial to consumers in choosing to eat fruit with difference in the accumulation of carotenoids.
