Figure 5 shows the ascorbic acid content of the coated and uncoated tangerine citrus var. Siam Banjar during storage at 25°C and 5°C. The ascorbic acid content in both coated and uncoated fruits decreased gradually as storage period was prolonged. However, these differences were not statistically significant (p ≥ 0.05). The results show that at the end of the storage period, treatment 10 and 12% wax coating, stored either at 25°C or 5°C had relatively higher value of ascorbic acid compared to the control. However, treatment 15% wax coating had lower value of ascorbic acid compared to the control. After 35 day of storage, it was observed that the combination of 12% wax coating and storage at 5°C is the most effective in preventing ascorbic acid losses from fruits, which had the highest value of ascorbic acid (38.64 mg/100 ml). The same trend was also observed in the previous study by Ahmed et al. (2007) who reported that orange fruit coated with 30% jojoba oil can reduce the loss of ascorbic acid in Valencia orange fruits compared to those uncoated ones.
