| Abstract Guava is very delicate and alluring fruit which is being ignored since very long time despite of highly nutritious fruit and rich source of Vitamin C. It contains Vitamin C 2-3 times more than orange. Naturally the guava fruit is enriched with vitamin C and polyphenoles. Guavas fruits after harvesting were dunked in solutions of CaCl2 (1, 2 and 3%) at room temperature for 5 minutes and stored for 24 days in 5% CO2 level at temperature of 10±1°C, while the humidity level of storage chamber were 80%. The stored fruits were analyzed at 6 days of interval for sugars (glucose, fructose and sucrose g/100g) total phenolic contents (mgGAE/100g), antioxidant activity (µmolTE/g), and organic acids (citric, tartaric, ascorbic, and malic acids mg/100 g).

| Abstract Vitamin C is imperative component of our nutrition and used as additive in many foods owing to its high antioxidant activity. The degradation of vitamin C content in orange juice during storage was evaluated in this study. Degradation of vitamin C in orange juice during 40 days storage at 0, 05, 15, 25, and 40 °C was analyzed and evaluated. Hydroxymethylfurfural (HMF) accumulation in orange juice acts as an indicator of ascorbic acid degradation. The initial vitamin C content in orange juice was 34.26 mg/100 mL that reduced when subjected to various storage conditions such as temperature and time. The loss of vitamin C during storage was lowest at 0 °C and the losses increased with rise in temperature. The Vitamin C content after 40 days in orange... |
