The invention relates to a method for processing retentate generated in film clarification process of fruit-vegetable juice production. The method comprises the following steps: mixing the retentate generated in film clarification process of fruit-vegetable juice production with a filter aid, injecting the mixture into an airtight external-pressure type film filter press, and carrying out filter pressing, so as to obtain liquid-phase clear juice and a solid-state fruit residue, wherein the liquid-phase clear juice can be used for producing fruit-vegetable juice products, thereby increasing the product yield, and the solid-state fruit residue is a solid substance which cannot flow, has the water content less than 25% and can be processed in a concentrative dumping manner or converted into animal foods. According to the method, the technical problem that the loss and the wastage are serious because the retentate generated in the film clarification process of fruit-vegetable juice production is difficult to process, solid and liquid phases are not thoroughly separated and the fruit-vegetable juice in the retentate cannot be adequately extracted is solved.
