Anwendungen & Verwendung
Occurrence
Maltose also is formed by yeast during breadmaking.
Verwenden
Maltose is a sweetener formed by the enzymatic action of yeast on starch. it consists of two dextrose molecules. maltose dissolves and crystallizes slowly in aqueous solutions, and is less sweet and more stable than sucrose. it is used in combination with dextrose in bread and in instant foods, and is also used in pancake syrups.
