Analysis of Vitamin C Content of Red Dragon Fruit (Hylocereus polyrhizuz) and White Dragon Fruit (Hylocereus undatus) in Storage with Different Temperatures and Times

Abstract

This study was conducted to determine the temperature and storage time of the exact vitamin C content of red and white dragon fruit and the difference of vitamin C. The samples were taken from the plantation land in Ubud Andong Highway, Petulu, Gianyar Regency. Treated for 10 and 30 days with 2, 10, 20 and 30⁰C temperature treatment with five repetitions using Completely Randomized Design Factorial pattern. Data obtained statistically using ANOVA (Analysis of Variance). The highest vitamin C content in red dragon fruit is 29.61 mg/ 100g temperature 10⁰C for 10 days and the lowest is in 30 days storage with temperature 30⁰C that is equal to 22,09 mg/ 100g. While the white dragon fruit content of vitamin C highest contained in storage with a temperature of 2⁰C is 22.69 mg/ 100g with maximum storage of 10 days and the lowest at a temperature of 30⁰C is 17.37 mg/ 100g.
