1. A process for modifying the characteristics of citrus fiber comprising:
hydrating citrus fiber;
subjecting the citrus fiber to a bleaching agent;
heat treating the hydrated and bleached citrus fiber at a temperature of from 50° C. to 140° C. for a period of 2 seconds to 60 seconds;
treating the hydrated and bleached citrus fiber to obtain homogenized citrus fiber;
washing the homogenized citrus fiber with an organic solvent to obtain organic solvent washed citrus fiber;
feeding the organic solvent washed citrus fiber through a screw press at a speed and pressure to obtain a dry matter content of about 30 wt %;
milling the screw pressed citrus fiber;
adding 40% to 60% solvent solution, comprising 70 wt % to 100 wt % solvent, to the milled citrus fiber, placing the milled citrus fibers in a vacuum drier, and vacuum drying the milled citrus fiber using heated water at a temperature of at least 95° C. for at least 4 hours, to remove the solvent from the milled citrus fiber, to form a vacuum dried citrus fiber;
comminuting or pulverizing the vacuum dried citrus fiber; and
recovering modified citrus fiber from the solvent solution;
wherein said recovered citrus fiber is dispersible in standardized water at a mixing speed of from 800 rpm to 1000 rpm to a 3 w/w % citrus fiber/standardized water solution having a viscosity is in a range of from 2000 mPas to 15000 mPas as measured at a shear rate of 5 s−1 at 20° C.
