Abstract

Brazil is the world's largest producer of Orange, being that most of the production intended for the manufacture of frozen concentrated juice (FCOJ). Due to their large volume of export and its high consistency (apparent viscosity), the knowledge of its rheological properties becomes necessary for better design of equipment and processes. In high-pressure homogenization (HAP), a non-thermal processing technology, the product is pressurized and forced through a small gap that dramatically increases speed followed by a sudden drop to atmospheric pressure, causing high shear stress and cavitation. These phenomena are able to change the structure of cells and biopolymers, impacting on the particle size and the way they interact, thus changing the rheological properties. The use of this technology in concentrated orange juice aims to decrease consistency, and other rheological parameters, facilitating operations like pumping, freezing, storage and transport. Even small reductions in viscosity and density will make great savings of energy and transport and storage, given the large volume of juice processed in Brazil. This work aims to evaluate the influence of high pressure homogenization pressure (0, 25, 50, 100 and 150 MPa) and number of cycles through the high pressure homogeneization valve, on concentrated orange juice rheological time nondependent and time dependent properties, particle size distribution and density, as well as, the reconstituted product's stability.
