Specifically, the grain enzyme diastase begins to convert starch in the grain to maltose. The baker's yeast enzyme maltase converts maltose into glucose, invertase converts any added sucrose to glucose and fructose, and zymase converts glucose and fructose to carbon dioxide gas which makes the dough rise, and alcohol which gives the baked bread ...
Maltose syrup. Maltose is a malt component, a substance obtained when the grain is softened in water and germinates. It is also present in highly variable quantities in partially hydrolyzed starch products like maltodextrin, corn syrup and acid-thinned starch. [10] Outside of plants, maltose is also (likely) found in sugarbag. [11]
The starch is first converted, by means of simple enzymatic hydrolysis, into high maltose syrup with di-, tri and oligosaccharides (2, 3 or more glucose units) having α(1,4)-glycosidic linkages which are readily digestible in the human intestine. These α(1,4)-glycosidic linkages are further converted into digestion-resistant α(1,6 ...
Mashing allows the enzymes in the malt (primarily, α-amylase and β-amylase) to break down the starch in the grain into sugars, typically maltose to create a malty liquid called wort. [ 1 ] The two main methods of mashing are infusion mashing, in which the grains are heated in one vessel, and decoction mashing, in which a proportion of the ...
The glands also secrete amylase a first stage in the breakdown of food acting on the carbohydrate in the food to transform the starch content into maltose. There are other serous glands on the surface of the tongue that encircle taste buds on the back part of the tongue and these also produce lingual lipase .
The first step in the production of high-fructose corn syrup is the treatment of cornstarch with α-amylase, which cleaves the long starch polymers into shorter chains of oligosaccharides. An α-amylase called "Termamyl", sourced from Bacillus licheniformis , is also used in some detergents, especially dishwashing and starch-removing detergents.
The drying step stops the sprouting, but the enzymes remain active due to the low temperatures used in base malt production. [20] In one before-and-after comparison, malting decreased barley's extractable starch content by about 7% on a dry matter basis and turned that portion into various other carbohydrates.

Hydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides so as to remove successive maltose units from the non-reducing ends of the chains This enzyme acts on starch , glycogen and related polysaccharides and oligosaccharides producing beta- maltose by an inversion.
