Abstract

Eggs are livestock products which contribute significantly to the fullfil nutrition need of community, because of one egg contains nutrients is complete and easy to digest. However, eggs have a short shelf life and only lasted 10-14 days at room temperature. This research aims to develop a preservation method of egg which efficient and halal. In this research, egg of domestic chicken (Gallus sp.) was coated with propolis extract of Trigona sp. Propolis extracted with two methods which were ethanolic extraction followed with aquadest extraction prior to application. Propolis extract applied by immersed egg inside propolis extract for 15 seconds, 30 seconds 45 seconds and 60 seconds with eggs without any coating designated as control. Eggs were kept in room temperature and change in egg quality (e.g. shape index, shell thickness, height of air cell) measured at 0, 7, 14, 21 and 35 days after the immersion. In the same time, alcohol content were tested with ester formation and Iodoform test. The results showed that propolis coating did not effect shape index, however maintained good shell thickness and height of air cell. Furthermore alcohol test did not showed sign of alcohol all treatment groups. Based on this study, it could be concluded that application of propolis extract as egg coating may increase egg shelf life while comply with halal regulation.
