Abstract :
Pectinases is a group of enzymes that catalyze hydrolysis of complex pectic polysaccharides of plant tissues into simpler form, for example, galacturonic acid. They are one of the enzymes that enjoy highest market place. Food industries at large depend on this group of enzymes. Functionally, these biocatalysts are being utilized widely in different industrial procedures like liquefaction, clarification, and extraction of fruit juice in food industries including in wine making. Their importance also lies in the fact that as enzyme they participate in the process that is less aggressive and less energy demanding vis-à-vis synthetic process. Enzyme mediated processing is thus said to be eco-friendly one. Pectinases utilized currently in the food industries are mostly derived from mesophilic or thermophilic microorganisms. But, some trends towards obtaining these enzymes from cold-adapted microorganisms is also being felt. The reason for this is the recognition of the fact that cold processing saves the nutritious quality and aromatic profile of the product. Cold-adapted microorganisms producing psychrophillic pectinases which work at low to freezing temperatures are known. Cold-active pectinases apart from being suitable for food industries for the reasons mentioned above, they are also considered to be a better alternative for various other applications like bio-refinery of pectic substances, bioremediation etc. This review describes information available on the cold-active pectinolytic enzymes, their substrates and industrial applicability of these enzymes in varied sectors.
