Enzymes In Wine Making Essay

651 words - 3 pages

Enzymes are biological catalysts which speeds up chemical reactions without being used up. There are three main factors which affect enzyme activity, and determines if their rate of reaction which are; sufficient energy (temperature), the pH, and the concentration. When there is a reaction, there must be energy around, the higher the energy, the faster the reaction because the particles will move faster therefore the chance of the particles to collide into each other will increase. However, if the temperature is too high or too low, the enzyme would denature and it will no longer work. This is similar to the pH; each enzyme will have a different optimal pH (a pH which an enzyme works best at) but if the pH is too high or too low, it will change shape and denature. Lastly as the concentration increases, so does the rate of reaction since more concentration means that there are more particles to react with. “To have a chemical reaction, there must be a least amount of energy which is called activation energy and enzymes help lower the activation energy therefore the speed of the reaction will increase”. People made wine for a long time without the help of enzymes in the winemaking process, but now pectinase is used around the winemaking society which enhances the process of wine making, however, there are limitations to use this enzyme. In this essay, the conditions that pectinase will need to be in will be analysed, and it’s affects economics and society.
Pectinase is commonly found naturally in fruits. Since pectinase is used in producing wine since the 1960’s people have been trying to find a way to produce a large quantity of this enzyme, which they found out that it can be extracted from the fungi: Asperguillus Niger. This fungus produces pectinase enzyme to breakdown the plants so that it could absorb the nutrients from the plant tissue and so that it will be able...

A variety of bacteria cultures may be used to ferment the milk, depending on the type of milk to be produced. The process differs for yoghurt production, at this stage, in that a mixture of enzymes, called rennet is added.BEERAs with yoghurt and cheese, the production of beer and wine dates back thousands of years. The fermentation in this

The History of Fermentation Essay

3748 words - 15 pages alcoholic percentage of over 14% would kill the fermenting enzymes. It takes a little more effort to make this pure substance than it does for the others. The first step could be the same as that in making wine. Fermentation simply has to take place somewhere; a grape yeast solution would be a good environment for the ethanol to be made but corn or soybeans could also be used. After the fermentation is done a distilling apparatus is set up. This

1995 words - 8 pages from Bacillus licheniformis or B. amyloliquefaciens. These enzymes are usable at high pH and temperatures up to 60o C, making them perfectly suited to the conditions found in a wash. Soon after amylases and lipases (to a lesser extent) began being used together with the proteases. This offered even greater cleaning power. While the proteases did the job of breaking down proteins, lipases could do the same to any fatty

THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY

651 words - 3 pages Enzymes are important to cells because they allow both the making and the breaking up of bonds. This would happen naturally and over time, but cells do not have the time to wait years, sometimes hundreds, for that to happen. With the use of enzymes, such tasks can take less than a second. This happens because enzymes are catalysts, and are able to speed up reactions. Enzymes, remaining unaffected by the process of catalysis, can continue to

Canada has the potential for almost 20 times that, which is still basically nothing in terms of Italy who produces 59 300 000 hL or 20% of the

The effect that temperature has on enzyme activity

1622 words - 6 pages reactions finished at 3 minutes and 30 seconds. This tells us that the optimum temperature for the enzymes to work at is located between these two temperatures, therefore making the optimum temperature close to body temperature. At 40C, the temperature was exactly right, so as not to deform the enzymes, but also to give them the maximum amount of energy, so that they are able to collide as often as possible with the right substrate, in this case
