Analysis Of Carica Papaya
The effectiveness of lemongrass essential oil incorporated into starch based bio-coating in lengthening the shelf life of Carica papaya (Papaya) was tested through the application of different concentrations of lemongrass essential oil and starch treatment on the papayas. The Peel Color Index (PCI) of each papaya was determined 4 days after the application of starch bio-coating.

It was observed that T1 has the lowest number of anthracnose rings present in the papayas. Anthracnose is a disease of fruit and vegetables that occurs in tropical areas caused by Colletotrichum spp. This infects immature fruits which only shows up after ripening (Solgi & Ghorbanpour, 2014). Even though lemongrass essential oil is anti-fungal, it did not prevent the anthracnose rings to occur. In an experiment conducted by Bevilacqua et al. (2011), lemongrass was tested on various spoiling bacteria such as Alicyclobacillus acidoterrestris, Bacillus coagulans, Lactobacillus plantarum, and Lactobacillus brevis together with other pathogens, yeasts, and moulds. The effect of lemongrass oil in these specimen are only selected. Some fungi reacted on the oil and was successfully prevented but some were not. In this study, Colletotrichum spp. cannot be penetrated by the lemongrass oil and therefore, has no effect in this kind of fungal activity of the fruit at its ripening phase.
Based on the data, there is a significant difference between the means of Peel Color and number of Anthracnose rings on the papayas in each treatment for Day 0 and 4. The results indicate that the lemongrass essential oil was unable to lengthen the shelf life of the
