A beverage formulation with proteins of high quality, inulin, Stevia and C vitamin has been prepared. The protein source was bovine plasma which was concentrated and demineralized by a combined membrane methodologies as microfiltration, ultrafiltration and discontinues diafiltration. The use of inulin as protective agent to prevent protein concentrate denaturation during freeze-drying was assayed. The inulin is a versatile food ingredient and it also has health benefits. The powder obtained has improved sensory characteristic and high solubility. Stevia has been added as sweetness, being a low-carbohydrate, low-sugar food alternative. The formulation could be destined as protein supplement with functional properties or for special dietary use.
