ABSTRACT
The temporal variation in the proximate content of sweet oranges based on three to seven days of post harvest provides valuable insights into the dynamic changes in proximate contents and mineral composition during fruit storage. The analysis revealed significant differences in key nutrients such as vitamin C, zinc, copper, sodium, and iron across the different stages of orange ripeness. Specifically, there was a notable decline in vitamin C, zinc, and copper content as the oranges aged, indicating potential degradation or loss of these essential nutrients over time. Additionally, the sodium content exhibited a significant decrease from day 1 to day 3, followed by a gradual decline thereafter, while the iron content remained relatively stable throughout the 7-day period. These findings underscore the importance of considering the timing of orange consumption to maximize nutrient intake and highlight the potential impact of post-harvest handling practices on the nutritional quality of Citrus fruits. Freshly harvested oranges may offer higher levels of certain nutrients, particularly vitamin C, compared to oranges that have been stored for several days. Therefore, consumers and stakeholders involved in the Citrus industry should be mindful of these variations in nutritional value when making decisions regarding fruit harvesting, storage, and distribution.
