An improved processing method and system for producing tomato paste and other food products affected by viscosity. Tomatoes are processed into tomato juice. The juice is provided to a decanter that separates or fractionates the juice into two portions—a thicker, more viscous cake portion and a thinner, less viscous serum portion. The serum portion is concentrated by removing a portion of water using an evaporator such as a thin film or juice evaporator. The cake portion can be concentrated if necessary with a drier. The serum and cake portions are re-combined to produce a tomato paste having improved color, texture, flavor and nutrition.

What is claimed is: 1. A system for processing a tomato juice stream to form a tomato product, comprising: a decanting centrifuge configured to receive the tomato juice stream, and fractionate the stream into a first portion comprising cake and a second portion comprising serum, wherein said first
What is claimed is: 1. A system for processing a tomato juice stream to form a tomato product, comprising: a decanting centrifuge configured to receive the tomato juice stream, and fractionate the stream into a first portion comprising cake and a second portion comprising serum, wherein said first portion has a greater viscosity than said second portion; an evaporator for concentrating said second portion; a drier for concentrating said first portion; a combination unit for combining said concentrated first portion and said concentrated second portion to form the tomato product; a sterilizer for sterilizing the tomato product; and a cooler for cooling the sterilized tomato product. 2. The system of claim 1, wherein the decanting centrifuge comprises a weir and a scraping mechanism, wherein rotating the decanting centrifuge forces the first portion against an inner surface of the decanting centrifuge, the weir separating the first portion and the second portion, and the scraping mechanism removing the first portion collected along the inner surface of the decanting centrifuge. 3. The system of claim 1, wherein the tomato juice stream is formed from raw tomatoes. 4. The system of claim 1, wherein said first portion comprises about 5 % to 35 % of the tomato juice stream. 5. The system of claim 1, wherein said first portion comprises about 5 % to 60 % insoluble solids. 6. The system of claim 1, wherein said first portion comprises about 3 % to 16 % soluble solids. 7. The system of claim 1, wherein said first portion has a concentration of about 3 to 13 brix. 8. The system of claim 1, wherein said first portion includes a majority of a color compound relative to said second portion. 9. The system of claim 8, wherein said color compound comprises lycopene. 10. The system of claim 1, wherein said first portion includes a majority of insoluble solids relative to said second portion. 11. The system of claim 1, wherein said second portion comprises about 65 % to 95 % of the tomato juice stream by weight. 12. The system of claim 1, wherein said second portion comprises about 0.01 % to 10 % insoluble solids by weight. 13. The system of claim 1, wherein said second portion comprises about 3 % to 17 % soluble solids by weight. 14. The system of claim 1, wherein said second portion has a concentration of about 3 to 16 brix. 15. The system of claim 1, wherein said concentrated second portion has a concentration of about 22 to 75 brix. 16. The system of claim 1, further comprising a processing system for processing tomatoes into the tomato juice stream. 17. The system of claim 16 wherein said processing system comprises: a chopper for cutting tomatoes into tomato pieces; and a pulper for removing solids from said tomato pieces. 18. The system of claim 17 wherein said pulper is configured to remove solids comprising skins and seeds by filtering said solids with a filter screen. 19. The system of claim 16, wherein said processing system comprises an enzyme deactivation system for inactivating one or more enzymes in the tomatoes. 20. The system of claim 19, wherein said one or more enzymes is pectin galacuronase or pectin methyl esterase. 21. The system of claim 19 wherein said enzyme inactivation system is configured to inactivate said one or more enzyme by subjecting the tomato pieces or tomato juice to a temperature of about 150 to 230 degrees Fahrenheit for a period of about 15 seconds to 10 minutes. 22. The system of claim 2, wherein said decanting centrifuge defines a first portion outlet through which said first portion collected against said inner surface of said decanter is removed. 23. The system of claim 2, wherein said decanting centrifuge defines a second portion outlet through which said second portion is removed. 24. The system of claim 1, wherein said evaporator concentrates said second portion at a temperature of about 190 to about 210 degrees Fahrenheit in a vacuum of about 10 to 30 Hg. 25. The system of claim 1, wherein said evaporator is a thin film evaporator, rising film evaporator, falling film evaporator, or a thermally accelerated short time evaporator. 26. The system of claim 1, wherein said tomato product comprises tomato paste.
