• Carrot juice
• Reverse osmosis
• Yield improvement

A new carrot juice production process has been developed to improve the yield of product to values higher than 80%. This result was obtained by properly processing, with consolidated technologies, both the liquid and the solid streams coming from the decanter of a traditional carrot juice industrial plant. In particular, the above-mentioned solid stream (waste of the decanter) was further processed by using an aqueous washing stream consisting of the endogenous vegetation water contained in the processed carrots. This stream can be obtained, in the required amount, in a reverse osmosis section which is fed with the liquid stream coming from the decanter of a traditional carrot juice production plant. A special feature of the proposed process is that it uses an endogenous washing vegetation water stream, thus avoiding any kind of contamination of the final product. A detailed description of the washing and the reverse osmosis section, the values of the corresponding operating parameters, and validation of the results obtained by calculation were reported and discussed.
