WebJan 23, 2024 · Maltose has the same molecular formula as sucrose but contains two glucose units joined together, whereas sucrose contains one glucose and one fructose unit. Yeast is then added and the mixture is kept warm (say 35°C) for perhaps several days until fermentation is complete. 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. Outside of plants, maltose is also (likely) found in sugarbag. In humans, maltose is broken down by various maltase enzymes, providing tw…
