The importance of enzymes in modern food biotechnology

Introduction:
The use of enzymes outside their natural environment in food technology gets more and more important. Although the application of enzymes as food additives or in processing raw materials has been used since a long time, it gets more and more popular and also crucial for many processes. Especially because enzymes are labelled with the GRAS (generally recognized as safe) tag, they are very desirable for industries and also consumers to use to convert raw materials into end products. Therefore, many chemicals, which could be harmful to the human body are replaced by enzymes or are tried to be replaced through the discovery of adequate enzymes. Enzymes can serve several functions,

Some of the currently used enzymes come from plants or animals, but the major source of enzymes are microorganisms. The purpose of this essay is to describe some of the most important areas of operation of enzymes in food biotechnology and to get an overview over the variability of enzymes. (Porta, et al., 2011)

Use of various enzymes in different areas of operation:
 Starch processing, sugar industry:
One of the most important process in food biotechnology is starch processing. Starch consists of amylose and amylopectin. They are built of glucose molecules, the only difference is the linkage between this molecules. Starch processing is used to convert starch originating from maize, wheat or potatoes into disaccharides or monosaccharides. A very big area of operation is the production of High Fructose Corn Syrup (High Fructose Corn Syrup). Three different enzymes are used in the processing of corn to the HFCS end product. The first step in HFCS production, which involves an enzyme, is liquefaction. The used enzyme is an alpha-amylase. The purpose of this enzyme is to convert the starch slurry into shorter-chain-length dextrins. The

They are hydrolytic enzymes, which play a major role in plant cell wall degrading. Xylanases can convert insoluble hemicellulose into water soluble parts, which can then bind water. Arabinoxylan is one of these hemicelluloses, which makes out 2-5% of flour. Even though it is only a small amount, it accounts for almost 30% of the water binding capacity and is therefore a very important component. That increases bread volume, decreases the firmness of the dough and finer crumbs are formed. Also the dough gets more machine-friendly and is therefore easier to handle. The characteristics of xylanases also depend on their origin, endoxylanases of Bacillus subtilis have different abilities than ones of Aspergillus niger. They can be used as an alternative to emulsifiers. (Butt, et al., 2008), (Collins, et al.,

    Sugar refers to carbohydrates. Sugars are employed by yeast during the early stages of fermentation. Extra sugars are used to increase gas production by the action of enzymes in the flour. By this way, it improves the crust colour and sweetens the bread. During baking, the reducing sugars in dough combine with amino acids from protein to undergo Maillard reaction giving attractive brown colours to the whole wheat bread.…

    2.4 Amylase’s Role in Bread Processing Bread making process is different from one company and the other company. There are many uniqueness of formula from each company but generally, the process is divided into three processes. The first step is dough mixing. The starch inside the flour can be broken by the alpha-amylase and will produce dissolved amylose which is the enzyme substrate to the next amylose degradation process. Starch hydrolysis process has a very important role to dough’s rheology characteristic because amount of water will be bonded by the hydrolyzed starch.…

    6. 1st step in this transformation is liquid-faction of the starch using acid or better using alpha-amylase. Employing this step we will hydrolyse the starch into smaller chains of polysaccharides with a ratter low Dextrose Equivalent setting up it for step. 7. The liquid-factions performed by a complete scarification to a high DE hydro lysate with amylo-glucosidase to an assortment of the monosaccharide dextrose and also smaller amounts of the disaccharide maltose and also lower polysaccharides.…

    Gluten is a protein matrix made up of the gluten forming proteins: glutenin and gliadin. These two proteins are unquie because when they are kneaded and hydrated, they associate with one another and form an elastic protein matrix. The function of gluten is to add elasticity to the product and trap the CO¬¬2 produced from the leavening agent to help the dough rise and shape. Yeast breads without gluten have difficulties trapping the CO¬2 within the bread structure and raising the bread because there is not enough elasticity. Gums, such as xanthan gum, can be added to help trap the gas bubbles but it is not a perfect substitute.…

    Products that are labeled “bran” or “all bran” are made from the outer bran coating of wheat grains (Brown, 2015). The bran of wheat includes residue from the milling, sifting, or other working of the grain. The aleuronic layer, located just beneath the bran, contains protein, phosphorus, thiamine, some fat, and other B victims. Bran provides the fibers cellulose and hemicellulose. Wheat bran is an insoluble fiber that functions as a stool softener (Brown, 2015).…
