Edible coatings on the post-harvest conservation of orange 'Natal CNPMF 112'

Citrus fruit have a lengthy post-harvest lifetime, however owing to water loss, they lose firmness and luster on the skin after being picked. In light of the foregoing, this study aimed to assess the effects of coatings on the post-harvest conservation of 'Natal CNPMF 112' oranges under refrigerated settings using aqueous and alcoholic propolis extracts and carnauba wax. Fruit of 'Natal CNPMF 112' orange tree grafted on 'Rangpur' lime were treated with carnauba wax (100%) and alcoholic and aqueous propolis extracts (30%). The experimental design was totally randomized, with the plots consisting of the coatings plus the control (distilled water), and the subplots separated by the storage time (0, 10, 20, and 30 days) at 12 degrees C +/- 2, with the exception of weight loss, which was assessed at three-day intervals (0 to 30 days). Loss of fruit mass, average fruit mass, soluble solids, titratable acidity, ascorbic acid, maturity index, pH, and technical index were all examined. According to the findings, the alcoholic extract of propolis produced decreased fruit mass loss, a high maturity index, and balanced acidity. The coatings used in the postharvest conservation of refrigerated 'Natal CNPMF 112' oranges had no effect on the other parameters. As a result, propolis alcoholic extract is suggested for the preservation of 'Natal CNPMF 112' orange.
