Carrageenans and pectins are widely used for their rheological properties in many foods, as well as industrial applications. In their processing, Degussa Texturant Systems uses ultrafiltration as a concentration step. The aim of this study was to compare organic flat sheet and mineral tubular modules for carrageenan and pectin concentrations. Mineral tubular membranes led to higher flux performances than organic flat sheet membranes. The comparison of energy and membrane renewal costs did not make it possible to draw definitive conclusions on the choice between both modules. Nevertheless, subject to a life expectancy of more than ten years and to high operating times, mineral membranes should be more economic to operate.
