Study Notes
Amylases in the Food Industry
Amylases are enzymes that hydrolyze starch and related complex carbohydrates into simpler sugars, such as glucose, maltose, and dextrins. They are widely used in the food industry for various applications, including starch modification, starch hydrolysis, and food processing.
Starch Modification
Amylases are used in the food industry to modify starch, which is a complex carbohydrate found in many foods like corn, potatoes, and wheat. The structure of starch comprises two main components: amylose, a linear polymer of glucose units, and amylopectin, a branched polymer of glucose units. Amylases can selectively hydrolyze these components, altering the functional properties of starch and making it suitable for specific uses. For instance, waxy corn starches are produced by treating starch with phosphates, which modify the functional properties of the starch granules and adapt them for special uses.
Starch Hydrolysis
Amylases are also used in the food industry for starch hydrolysis, which is the process of breaking down starch into smaller sugars. This is accomplished by breaking the intra- and inter-molecular bonds, resulting in dextrins, maltose, and glucose. The rate of starch hydrolysis is accelerated by heat, extremes in low pH, and enzymes (e.g., amylases), making them indispensable in food processing and preparation.
Food Processing and Preparation
Amylases play a crucial role in food processing and preparation. They are used to modify the texture, viscosity, and taste of various food products. For example, in the production of beer, amylases are added to the mash to break down starch into fermentable sugars, such as maltose. This allows the yeast to convert these sugars into alcohol and carbon dioxide, resulting in the fermentation of beer.
In the baking industry, amylases are used to improve the quality of baked goods by altering the structure and functionality of starch. They can help increase the bread's volume, improve its texture, and enhance its flavor.
Beverage Industry
Amylases are also used in the beverage industry for various purposes. For instance, in the production of juices, amylases are used to hydrolyze starch into fermentable sugars, which can be converted into alcohol by yeast. This process is known as alcoholic fermentation, and it is used to produce alcoholic beverages like wine and cider.
In the soft drink industry, amylases are used to hydrolyze starch into fermentable sugars, which can be used as a source of energy for microorganisms during the production of non-alcoholic beverages.
Conclusion
Amylases play a crucial role in the food industry, contributing to the production of various food and beverage products. They are used for starch modification, starch hydrolysis, and food processing and preparation, making them indispensable in the industry. By breaking down complex carbohydrates into simpler sugars, amylases help improve the quality and functionality of food products, ensuring they meet the nutritional and sensory requirements of consumers.
