Abstract
Abstract Low viscosity orange juice concentrates which are useful in preparing high Brix concentrate products that are less pseudoplastic at freezer temperatures and are more highly dispersible when reconstituted with water are disclosed. These low viscosity orange juice concentrates are obtained by subjecting concentrated orange juice to high shear treatment for a period of time sufficient to reduce the mean particle of the sinking pulp at least about 40 microns and thus lower the viscosity of the concentrated juice. The mean particle size of the sinking pulp in these low viscosity orange juice concentrates is typically about 125 microns or less.
