Industrial uses of enzymes

Extracts from this document...


Industrial uses of enzymes Most of the reactions catalysed by enzymes have commercial or industrial uses. These reactions used to happen by using high heats or strong acids but no enzymes can be used in these industrial processes. Here are just a few ways they can be used. Biological washing powders use the enzyme protease. This is enzyme is used to break down protein stains for example food and blood. The enzymes need alkali conditions to work there best and the detergents provide this. And as the enzymes work at relatively low temperatures this means the washing machine does not have to work at high temperatures. This is one advantage to using enzymes in biological washing powder. This is an economic advantage because the washing machine is not using, as much heat so it will not be using as much energy and this will be saving on the cost of your electric and heating bills and the cooler the temperature the kinder it is to your clothes so they last for longer. ...read more.


This used to be done with a mixture of chemicals, but these chemicals produced harmful poisonous gases so an alternative was needed. Also the skin of the animal needed to be made more pliable and to do this the fats needed to be removed. The enzyme protease is used to perform these processes. Protease is applied to the underside of the animal skin and left to diffuse through to the hair follicles the protease then partly digests the keratin found in hair and this allows the hair to be removed more easily. The enzymes that are used to digest or remove the fat from the animals skin are extracted from the pancreas of slaughtered animals. Using Enzymes to perform these processes is an advantage to the environment because harmful chemicals are no longer being used, so less harmful waste is being produced which is kinder on the environment. ...read more.


The baking industry uses enzymes to modify the flour they bake with to prevent the bread from becoming stale too quickly. Lactase is used when making cheese and other dairy products containing milk because it reduces the amount of lactose. Enzymes are used to convert starch into sugar and sugar in to alcohol. When making alcoholic beverages. Enzymes are also very important when it comes to the digestion of animal feed components. Enzymes are added to the natural enzymes that are found in animals, these help break down the raw feed materials in the animal's digestive system. This is especially important in young animals whose digestive system is not fully developed. This is an advantage because it enables young livestock to be fed better quality food which they can properly digest which will then provide a better tasting product e.g. steak when it comes to be slaughtered and prepared for sale. In all the industrial uses of enzymes I have looked at I think that in every case the advantages out way the disadvantages. ...read more.
