The weight of coated fresh-cut apples was detected to analyze the efficiency of these coatings acting as water loss inhibitor over the experimental time. As time went on, weight of apple slices decreased gradually (Fig. 2). Over the experimental storage period, the variation trend of all the apple slices was similar. All the coated apples demonstrated their good ability of water loss inhibition when compared with the control apple slices. The weight loss ratio of apple slices coated with nothing was more than 15% while the others were less than 14%.
