Abstract
The effect of temperature and soluble solids concentration on density of clear pineapple juices was studied. The density was determined with soluble solids content from 10 to 64.1°Brix, and temperatures between 10 to 70°C with 10°C increments. The aim of this work was to develop suitable mathematical models for the use in concentration process by evaporation. The density of pineapple juice was strongly affected by soluble solids concentration, while it was relatively less affected by temperature. Different models were developed as a function of soluble solids content and temperature.
