INSOLUBLE PROTEIN PARTICLES

摘要

Insoluble, denatured, heat-stable protein particles are used in food and beverage products. The particles are easily dispersible in aqueous solutions and take the form of substantially non-aggregated macro-colloids. In a hydrated state the preferred mean diameter particle size distribution of the insoluble, denatured, heat-stable particles ranges from about 0.1 microns to about 3.0 microns, with less than about 5 percent of the total number of particles exceeding about 3.0 microns in diameter. The majority of the particles are substantially spheroidal in shape and have a substantially smooth, emulsion-like organoleptic character similar to that of high-calorie fats and oils. Additionally, these particles have a degree of protein insolubility of at least about 80%, which provides processing advantages during heat treatment.
