Commercial Uses of Enzymes The use of enzymes to modify foods has increased vastly and these fermentations are continuing to be important, however, a new type of enzyme industry has evolved which involves the use of harvesting enzymes from microorganisms. The production of enzymes from bacteria and fungi can be isolated from the growth media and cleansed and purified as necessary. Generally in industrial processes the enzyme is immobilised which allows t h enzyme to be re-used and also enable the products to be separated easily. The production of textiles, paper, leather fruit juices and biological detergents are produced from Microbial enzymes.…show more content…
Microbial proteases can also be used in clarifying fruit juices and also in beer by terminating the protein haze. They can also be used in the digestion of fish livers to permit improved withdrawal of fish oil, tenderisation of meat and alteration of proteins in flour used for bread making. Pectinases The job of pectinases is to degrade pectins, which are polysaccharides, found within plant cell wall structure into shorter molecules, which are known as galacturonic acid. Pectin can turn into jelly that comes in use for products such as jams however not adequate in fruit juices and other liquids. Pectinases are obtained from fungi like Aspergillus’s and Penicillium. Other bacterial and fungal pectinases are used in destroying and rotting of fruits and vegetables. The biggest uses of pectinases are probably in the purification of fruit juices. They are added to fruit that has been crushed like grapes. This increases the yield of the juice extracted and also improves the colour derived from the fruit skins. Cellulases These break down cellulose into smaller chains and then into disaccharides cellobiose and to β-glucose. Cellulases currently have little use in the food industry however can be used in improving the release of colour form fruit skins and removing the haze from beer
