Abstract

Papaya (Carica papaya L.) is one kind of fruit plant that grows in many tropical regions and various kinds. Papaya much loved Indonesian society. Chemical content of papaya fruit such as β-carotene is a provitamin A, which are crucial for the formation of vitamin A. The purpose of this study was to determine the content and the levels of β-carotene in papaya Bangkok, papaya Hawai, papaya California. Fresh papaya that has been mashed mixture extracted with hexane: acetone: ethanol (2: 1: 1) v/v with maceration method. Results of extraction used for qualitative and quantitative analysis. Quantitative analysis of β-carotene using UV-Vis spectrophotometry at a wavelength of 452.0 nm. Qualitative test results showed that papaya Bangkok, papaya Hawai, and papaya California tested positive for β-carotene. Average levels of β-carotene papaya Bangkok amounted to 9,6094 mg / 100 g, papaya Hawai at 11,0345 mg / 100 g, and papaya California amounted to 6,5925 mg / 100 g. Βeta-carotene levels from high to low at the papaya Hawai, papaya Bangkok and papaya California. The results of the analysis using One Way ANOVA showed a significant difference between the levels of β-carotene papaya Bangkok, pepaya Hawai, and pepaya California (P = 0.00).
