Abstract: The invention relates to a method for reducing water consumption of a system (1) for processing a liquid or semi-liquid food product, after an interruption of said processing. The food product is a composition of a first sub-composition having a low concentration and a second sub-composition having a high concentration, wherein said high concentration is greater than said low concentration. The method comprising the steps of pushing said first sub-composition, said second sub-composition and said food product out of the system (1) using water until the system (1) substantially contains only water, sterilizing the system (1) by heating the water present in the system (1), and forming a new food product by adding a new second sub-composition to the sterile water, thereby using said sterile water as said first sub-composition.

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: It is provided a processing system for processing a liquid or semi-liquid food product. The food product is a composition of a first sub-composition having a low concentration of particles and a second sub-composition having a high concentration of particles. The high concentration is greater than said low concentration. The processing system comprises a first mixing tank for mixing said first sub-composition, a second mixing tank for mixing said second sub-composition, and a heat treatment apparatus arranged to receive said first sub-composition and said second sub-composition and to heat treat said first sub-composition and said second sub-composition.

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.

Abstract: To extend shelf-life, a method of heat-treating a food packed in a packaging container of a packaging laminate comprising a layer of paper or paperboard and outer, liquid-tight coatings of plastic. The 9ackaging container is exposed to a liquid heating medium sprayed against outer walls of the packaging container to heat and hold the food at a predetermined treatment temperature during a predetermined period of time so as to exterminate, eliminate or deactivate harmful microorganisms inside the packaging container. Thereafter, the food is cooled by cold water sprayed against the outer walls of the packaging container. To avoid the risk that liquid penetrates into exposed incision edges on the outside of the packaging container during the heat treatment, the packaging container, before this treatment, is brought into contact with a hydrophobic impregnation agent for absorption and penetration of the hydrophobic impregnation agent in the exposed incision edges.
