FLOW BEHAVIOR OF SOME FRUIT JUICES

Abstract

Juice production is known to be one of the important and critical industries as it involves products that are delivered and consumed by people. Strict parameters should be maintained in order to deliver safe product from raw materials delivery and semi-finished product processing to end product handling. The demand for juice in Egypt has increased widely to call for new product innovations and concepts since it is a country with high potentials of market growth. Upon processing juice, identifying the juice type whether it’s high on fruit content, artificial fruit drink or juice mix is mandatory as it strongly assists in identifying the optimum processing parameters. Juice production schemes can differ depending on whether the starting point is production from juice concentrate or juice fruit. The fluid behavior in each processing step starting from ingredients mixing up to heat treatment should be known as it serves in the ideal handling for the juice and maintaining the product quality. This results in providing premium juice for end consumer and can be studied through Rheology. Rheology is the study of flow behavior and deformation of fluid upon applying certain force and analyzing the flow behavior in response to time, temperature change and deformation
