Pectic substances hairy regions

The classification of pectic enzymes in general, their occurrence in higher plants and micro-organisms and the properties of pectic enzymes from some plants and food grade micro-organisms are described with special emphasis on their substrate specificity. Their technological roles and applications, also in combination with (hemi-)cellulases, in a variety of processes are discussed. Evidence is presented for the existence of a new type of pectic enzyme which acts specifically in the hairy regions of pectic substances.
