Quality of food powder can be defined in many ways using parameters such as moisture content, absolute or bulk density, hygroscopicity, degree of caking and reconstitution time and reconstituted paste properties. Reconstituted juice was indicated by the quality changes in color, rheology and acidity comparing to those of feed. (Haugaard et al., 1978; Pisecky, 1985) Choosing the criteria for evaluating food powder qualities is dependent upon its function. For instance, flavoring food powder requires high retention of flavor or volatile. For milk powder, consumer expects the product that has high nutrition and good solubility. For tomato powder, the reconstituted paste characteristics as well as flavor should have the same as that of tomato paste.
