Role and Application of Pectic Enzymes

Table III. Technological roles and applications of pectic enzymes...

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. 

More knowledge of physical and chemical properties of pectic enzymes, their substrate specificity, pattern of action, action on plant tissues, interaction with each other and other polysaccharide degrading enzymes is essential to establish their technological roles and to improve existing applications and to develop new applications.
