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.

La présente invention concerne des particules de protéine insolubles, dénaturées, stables à la chaleur, s'utilisant dans des produits alimentaires et des produits de boisson. Ces particules, qui se prêtent facilement à la dispersion en solutions aqueuses, prennent la forme de macro-colloïdes sensiblement non agrégés. A l'état hydraté, la répartition des calibres du diamètre moyen préféré de ces particules insolubles, dénaturées, stables à la chaleur va d'environ 0,1 ?m à environ 3 ?m. Les particules, sont dans leur majorité sensiblement sphéroïdes, présentent un caractère organoleptique sensiblement souple s'apparentant à celui de l'émulsion, proche de celui des graisses et huiles fortement caloriques. En outre, ces particules le degré d'insolubilité d'au moins 80% environ de ces protéines est avantageux pour le traitement à la chaleur.
