The effect of oregano essential oil as a coating on the quality of fresh-cut guava fruits<br />

(Psidium guajava L.) were studied. Guava slices were coated with different<br />

concentration of oregano essential oil at 0.2, 0.4, and 0.6 % w/v. The treated freshcuts<br />

were kept at 5 °C for 15 days. The results showed that the coated fruit at all<br />

concentrations statistically significant between treatments in reducing weight loss,<br />

firmness and maintain L* value (lightness) on surface of guava during storage.<br />

However, there was no significant effect on total soluble solid (TSS) of fresh cut guava<br />

among all treatments. Sensory evaluation showed that 0.2 % coated guava was the<br />

most acceptable sample. These results demonstrated that oregano essential oil has<br />

an ability to prolong the shelf life and maintain characteristics of the fresh-cut guava<br />

fruit.<br />
