Produits dérivés des fruits et légumes — Détermination de la teneur en matière sèche par dessiccation sous pression réduite et détermination de la teneur en eau par distillation azéotropique

The method of determination of dry matter content consists in heating to constant mass, after mixing, of liquid or semi-liquid products spread over an absobent surface, or of pasty products mixed with an inert powder, at 70 °C under reduced pressure. The method of determin of water content consists in entraining of the water in the form of vapour by a volatile solvent immiscible with water, condensing and separating in a reflux trap, recovering and measuring of the volume of water in a graduated tube.
