A process is disclosed for modifying citrus fiber. Citrus fiber is obtained having a c* close packing concentration value of less than 3.8 w %, anhydrous basis. The citrus fiber can have a viscosity of at least 1000 mPa·s, wherein said citrus fiber is dispersed in standardized water at a mixing speed of from 800 rpm to 1000 rpm, to a 3 w/w % citrus fiber/standardized water solution, and wherein said viscosity is measured at a shear rate of 5 s−1 at 20 C. Citrus fiber can be obtained having a CIELAB L* value of at least 90. The citrus fiber can be used in food products, feed products, beverages, personal care products, pharmaceutical products or detergent products.
