- Duck eggs have a very high protein content. The obstacle faced at this time is that eggs have large shell pores, which speeds up the evaporation process. Efforts made to overcome this problem are soaked with guava leaf extract and chitosan solution. This study aims to study the effect of immersion using guava leaf extract and chitosan solution on the physical quality of local duck eggs. This research was conducted from August to September 2018 at the Animal Nutrition and Food Laboratory of the Livestock Study Program of the Faculty of Agriculture, Sriwijaya University. The study used a completely randomized design (CRD) consisting of 7 treatments and 4 replications. Each test consists of 2 eggs. The number of eggs in this study was 56 items. The treatment consisted of T0 (Without guava leaf extract and chitosan solution), T1 (Immersion with guava leaf extract 0,5%), T2 (Immersion with guava leaf extract 1,5%), T3 (Immersion with guava leaf extract 1,5%), T4 (Immersion with chitosan solution 0,5%), T5 (Immersion with chitosan solution 1%), T6 (Immersion with chitosan solution 1,5%). The results showed that immersion of eggs using guava leaf extract and chitosan solution significantly (P> 0.05) on weight loss, white pH and haugh egg unit while not significantly (P <0.05) on the pH of egg yolk. The conclusion of the research is that immersion chitosan solution has better results to maintain the physical quality of eggs such as weight loss, pH of egg white and haugh unit compared to preservation using guava leaf extract but the two tanners are not able to maintain the pH of egg yolk.
