Abstract: A system for processing a liquid or semi-liquid food product is provided. The food product is a composition of a first sub-composition having a low concentration, such as water or a sugar solution, and a second sub-composition having a high concentration, such as a concentrate. The high concentration is greater than the low concentration. The system comprises an ultra violet (UV) light treatment apparatus for reducing an amount of microorganisms in the first sub-composition and a blending apparatus for aseptically combining the first sub-composition and the second sub-composition into the liquid or semi-liquid food product.

Abstract: A system, method and computer-readable medium for producing a pasteurized liquid product. The system comprises a first supply comprising a concentrate having a water content being less than that of the desired liquid product; a second supply of water and/or sugar solution; a first heat treatment device connected to the second supply and being arranged to heat the water or sugar solution to a predetermined temperature for reducing a number of microorganisms in the water or sugar solution; at least one combiner connecting the first supply with the heat treatment device, and configured to combine the heated water or sugar solution with the concentrate to form a liquid product, wherein the predetermined temperature of the water or sugar solution is set such as to reduce a number of microorganisms of the liquid product by the heat energy of the heated water and/or sugar solution.
