In this study the factors that affect the quality of water melon during storage is divided into four episodes, the first study of the chemical and physical properties of water-melon, the amount of soluble solids, total 9.07 0Brix, total acidity percent. 0:07, acidity - alkalinity (pH) 5.71, the L * 30.90, a * 37.49, b * 23.75, the stability of turbidity. (% Transmittance) 53.47 and sedimentation rate (% The precipitation rate) 2.29 The second effect of the acid - base. The quality of watermelon during storage that can not be maintained at pH 2-9 turbidity of water melon has the third effect of the stabilizers on the stability of the turbidity of water melon during storage. The use of the three types of stabilizers xanthan gum, methyl cellulose, carboxymethyl. Carradine and Carrageenan. At a concentration of 0.10, 0.20 and 0.30% (w / v) found that only xanthan gum type is only one constant turbidity of water melon save. The viscosity and to maintain the stability of the turbidity is proportional to the concentration of xanthan gum increased. By xanthan gum at 0.10% (w / v) received the most likes. Take it to the next step in the four study shelf life and the changes in place. During the storage of water melon. By counting total microorganisms found in watermelon stored at 4-5 ° C can be stored for four weeks, but the quality of physical decline. However, the product is stable throughout its shelf life.
