The invention relates to a process for producing a non-caloric citrus albedo bulking agent comprising obtaining albedo from citrus peels to produce albedo particles substantially free of flavedo, water-washing to reduce soluble carbohydrates, constituents, removing alcohol and water, and bitter constituents, removing alcohol and water, and finally milling to the consistency of flour. The citrus albedo bulking agent obtained from this process is especially useful as a partial replacement for high-caloric ingredients such as flour, fat and/or sugar in a food product with at least a one-third reduction in caloric density, more preferably from 50% to 75% or higher. The citrus albedo bulking agent has a water binding capacity of from 10 to 20 grams of water per one gram of the albedo bulking agent.
