Effect Of Adding Different Levels Of Citric Acid On Quality Attributes Of Beef Burger

Abstract

The study was conducted to evaluate the effect of adding citric acid on the shelf life and quality of beef burger. Different levels of citric acid were added, (0% control, 0.8and 1 %). Six kilograms of beef were divided into three groups with 3replicates. Chemical composition, Cooking loss, water holding capacity (WHC ( , pH, total bacterial counts and sensory evaluation were determined. The chemical analysis showed significant differences in moisture content, protein, fat , ash and pH as citric acid levels increased .the moisture content significantly decreased from (70.43 ±0.32 )to( 69.95 ±1.1)at(P
