Abstract

Apple cell wall materials (CWMs) exhibiting different degrees of cell walldegradation were prepared by the application of maceration and liquefaction enzymes (control sample without treatment), and their physico-chemical properties were investigated. Different methods were used for the determination of the water binding behaviour and the theological properties. It was found that the standardized analysis methods gave results of limited correctness depending on the sample type and on the sample pre-treatment. Aggregates, formed during the drying of apple CWM that was treated with liquefactionenzyme, could be re-dissolved by mechanical stress (stirring) during rehydration. The stirring improved the detected functional properties (water binding and theology) of the material to a great extent. It has to be realizedthat the analysis methods including the sample pre-treatment have to be adapted to the type of sample material. Furthermore the investigations showedthat the water binding properties of CWMs do not simply correlate with separate parameters such as porosity, pec tin content or the remaining naturalgrown cell structure. Probably, the functional properties are influenced mutually and multivariately by many material attributes.
