In recent years, interest in edible flowers has increased. The problem that arises with edible flowers is that this commodity is perishable quickly, cannot be stored for long, and is required to be fresh. One alternative technology that can be done to increase the shelf life of carnations is to use carrageenan and chitosan edible coating applications. The purpose of this research was to examine the effect of using edible coatings of carrageenan and chitosan on changes in the quality of carnation flowers and to determine the best coating solution treatment based on the shelf life of the carnations produced. The results showed that the best treatment was coating with 0.1% chitosan solution (Q1) which was able to maintain the water content, weight loss, and hue values of 79.61%, 7.93%, and 26.62° to 6 shelf life with panelists' acceptance on score of 3 (from 0-5) based on color and freshness. Meanwhile, flowers without coating treatment (control) had moisture content, weight loss, and hue values of 74.01%, 11.68%, and 24.13°. However, these results may need to be reviewed with the same experiments in near future because the chitosan material used is categorized as technical material whose quality is unknown. The material used for coating should refer to Badan Standarisasi Nasional (BSN).
