摘要

In this study, the effectiveness of six methods for preserving sweet orange fruits was examined. The preservative methods considered are the treated wooden box (TWB), untreated wooden box (UWB), treated paper carton (TPC), untreated paper carton (UPC), treated native basket (TNB) and untreated native basket (UNB). A number of sweet orange fruits were preserved for 5 consecutive weeks using the six preservative methods. Certain quality characteristics on the orange fruits were observed and recorded at the end of each week. The efficacy of each preservative method relative to others was determined by the observed retained quality characteristics in the oranges at the end of the study period. Various results obtained from analysis of variance on the data revealed that the six preservative methods performed differently at preserving the observed quality characteristics on the sweet orange fruits over time (p < 0.0001). Among the six methods considered, results from this work showed that the treated paper carton (TPC) was the best method for preserving sweet orange fruits in Nigeria. Further results showed that the quality of the oranges, based on the six measured quality characteristics, depreciated as the length of preservation period increases irrespective of the method of preservation used. Data for this study were collected as extracts from the record of the Nigerian Stored Products Research Institute (NSPRI), Ilorin, Nigeria. Based on the results from this study, it was discovered that while TPC \(\left(\overline{x}=76.38,SD=21.28\right)\) is the best preservation method for sweet orange fruits, while UNB \(\left(\overline{x}=25.98,SD=28.55\right)\) is the worst method. To avoid wastage of this fruit and ensure that sufficiency is achieved year round, it is recommended that farmers should give attention to the practices adopted for preserving orange fruits as well as storage periods.
