Abstract
Method for producing tomato paste and powder using both reverse osmosis and evaporation. A tomato juice is separated into a juice and a first pulp. The juice is clarified with a centrifuge and/or filter to produce a clarified juice and a second pulp component. The clarified juice is processed with reverse osmosis to produce a pre-concentrated juice by removing a first portion of water. The pre-concentrated juice is provided to a multi-effect evaporator, which removes a second portion of water to form a concentrate. Thermal vapor recompression can be used to recycle steam that is used during evaporation. The concentrate is mixed with the first pulp component or a pulp mixture to produce an intermediate paste, which is processed to produce a tomato paste by combining juice and pulp components. Tomato powder can also be produced.
