Three hundred and twenty (320) oranges of Valencia variety were stored under cold conditions in the refrigerator for 8 weeks. The following parameters were carried out during the course of storage: Total soluble solids, titratable acidity, weight loss, firmness, pH, vitamin C and sugar/ acid ratio. The final value for firmness for coated oranges was found to be 1781.25 + 118.30N, while that of uncoated oranges was 1531.25 + 185.53N. The pH was gradually increasing during the course of storage in the two treatments, whereas vitamin C was found to be decreasing in storage. The total soluble solid for coated oranges was 9.79+ 1.14% while that of uncoated oranges was found to be 9.34 + 0.06% at the end of storage. There was a linear decrease in titratable acidity during the course of storage. It was found that the value obtained for coated oranges was higher than that of uncoated oranges which was obtained to be 1.14 + 0.07 at the end of storage. Converse to this was obtained for % weight losses in the two treatments. The weight loss for coated oranges was 29.20+ 0.55%, while that of uncoated oranges was 53.30+ 1.17% at the end of storage. A linear increase was observed in sugar/acid ratio in the two treatments during the course of storage with higher value being recorded for uncoated oranges as 8.90 + 0.87, while lower value was gotten for coated oranges as 7.43+ 0.34%.
