To produce good-quality clarified juice (Vaillant et al., 1999), the enzyme liquefaction treatment carried out before membrane filtration has the advantage of not only lowering the juice viscosity but also of reducing the SS content. Insoluble solids can then be re-concentrated by microfiltration until the concentration is the same as the original juice. The clarified juice can thus be extracted without lowering the retentate's economic value. This methodology, if it were applied in a plant producing pulpy juice, would not generate waste or by-products and would diversify the range of products being offered. The costs of producing clarified juice would also be highly competitive, compared with other established processes and would have a higher production yield. For tropical fruit juice industries, it represents a real alternative method to diversify production and increase market share. This methodology also allows fully continuous processing that can be easily integrated into the normal processing line and can also be automated. Indeed, in the trials, permeate flows seem to remain almost constant, not showing the classical decrease observed during microfiltration done in concentration mode.
