Abstract
The rheological behaviour of two different loquat juices was studied. Juices containing pectins and pulp exhibited non‐Newtonian with yield stress behavior. Juices from which pectins and pulp were removed exhibited Newtonian behavior. The Bingham model described the relationship between shear stress and shear rate for the first type of juice and the Newtonian model described the second type. The effect of temperature on the Bingham plastic viscosity and the Newtonian viscosity was described by Arrhenius equation. The effect of soluble solids contents was described by power‐law and exponential expressions. Finally, two equations that described the combined effect of temperature and concentration were developed.Keywords
