The study was conducted to investigate the effectiveness of beeswax containing<br />

coconut oil and sunflower oil as coating to maintain postharvest quality of tomato.<br />

Tomato fruits were coated with three different amounts of beeswax (5, 15 and 25 g)<br />

and stored at 10 °C for 30 days. The results showed that uncoated fruits showed<br />

higher percentage of weight loss, L* and b* values of fruit skin, total soluble solids<br />

(TSS), titratable acidity (TA), and pH than coated fruits during storage. Coating<br />

treatments could delay declining firmness, TSS and TA percent, a* value of fruit skin,<br />

as well as bioactive compounds such as lycopene content. The coated fruits with 25 g<br />

beeswax showed significantly lower percentage of weight loss than other treatments.<br />

The results suggested that postharvest application of beeswax containing coconut oil<br />

and sunflower oil have a potential to extend storage life of tomato fruits by maintaining<br />

fruit quality.<br />
