Résumé

The aim of the study was to evaluate a new process based on crossflow microfiltration for concentration and partial purification of lycopene from watermelon. The process included sequentially juice extraction, enzymatic liquefaction, crossflow microfiltration and centrifugation. Different technological schemes were compared including or not a diafiltration step in order to remove soluble solids and increase lycopene purity. Microfiltration was performed at 50-60 °C using alumina tubular membranes with average pore diameter from 0.2 to 1.4 m and varying the transmembrane pressure from 0.5 to 2.0 bar. Using the best operating conditions at the crossflow microfiltration step, permeate flux was close to 110 L.h-1.m-2 and lycopene concentration was increased 11 times in the retentate. Centrifugation at 10,000 g for 10 min, enabled to enhance lycopene concentration up to 4 times. Diafiltration allowed to decrease total soluble solids from 100 to 20 g.kg-1 and so to purify lycopene further. No cis-isomerization was highlighted that proved that the process maintained carotenoid integrity. Finally, the optimal processing scheme allowed to obtain a natural extract of lycopene 42 times more concentrated and 34 times purer than the initial juice. The results looked very promising for industrial application even if economic viability has still to be assessed.
