| Abstract: | This paper focused on the relationship of ohmic heating rate and conductivity for liquor food (liquid food, hydrophilic colloid and liquor food containing particles). The conductivity of food material is the main factor that influences the heating rate. The higher the conductivity, the quicker is the ohmic heating. The effect of pH value is reflected in its ability in increasing the acidity, therefore increasing the conductivity of liquid food. This study contributes to studying electric heating properties of food and developing food products of higher quality. |
