Pengaruh Edible Coating dengan Konsentrasi Berbeda terhadap Kadar Protein, Daya Ikat Air dan Aktivitas Air Bakso Sapi Selama Masa Penyimpanan

The aim of this research is to know the influence of different concentration from edible coating to protein, water holding capacity and water activity of beef meatball at shelf life period. The experimental design that is used in this research is Randomized complete design by 5 treatments and 4 repetitions. The treatment that is applied in this research is immersion in different concentration from edible coating. The result of this research shows that the treatment of different concentration from edible coating (0%, 0.5%, 1%, 1.5% and 2%) in beef meatball at shelf life period has an significantly affected (P<0.05) to protein, water holding capacity and water activity. Continually result of protein is 12.12%, 11.87%, 10.95%, 10.79% and 10.72%. Continually result of water holding capacity continually is 32.07%, 34.47%, 26.64%, 20.43% and 17.64%. Continually result of water activity is 0.949; 0.954; 0.944; 0.944 and 0.947. The best result of protein, water holding capacity and water activity to edible coating treatment is on concentration 0.5 %. The advice of this research is the use of edible coating concentration 0.5% method can be applied because it can keep the quality of the protein, water holding capacity and water activity from beef meatball
