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.

Analisis Kandungan Vitamin C Buah Naga Merah (Hylocereus polyrhizuz) dan Buah Naga Putih (Hylocereus undatus) pada Penyimpanan dengan Suhu dan Waktu yang Berbeda. INTISARI Penelitian ini dilakukan untuk mengetahui suhu dan lama penyimpanan terhadap kandungan vitamin C yang tepat pada buah naga merah dan putih serta perbedaan kandungan vitamin C. Kandungan vitamin C tertinggi pada buah naga merah yaitu 29,61 mg/100g suhu 100C selama 10 hari dan terendah terdapat pada penyimpanan 30 hari dengan suhu 300C yaitu sebesar 22,09 mg/100g. Sedangkan pada buah naga putih kandungan vitamin C tertinggi terdapat pada penyimpanan dengan suhu 20C yaitu 22,69 mg/100g dengan penyimpanan maksimal 10 hari dan terendah pada suhu 300C yaitu 17,37 mg/100g. Kata kunci: buah naga merah, buah naga putih, vitamin C, suhu dan waktu penyimpanan
