In recent years,
Haruyutaka, a Hokkaido-grown wheat, has attracted attention for its favorable
bread-making characteristics. The quality and properties of Haruyutaka flour
were examined, and bread made from Haruyutaka flour was evaluated in terms of
staling. Thus this study seeks to make a determination on whether Haruyutaka
wheat is suitable for bread making. Data measuring the physical and
fermentative properties of a dough made from Haruyutaka flour and a control
dough indicates that Haruyutaka wheat produces a dough with greater
extensibility and superior fermentative properties. Bread quality was
investigated by preparing white bread using a straight dough method and a
sponge dough method. After baking, the bread was stored for a 72-hour period.
Specific volume, quantity of soluble starch, wheat starch gelatinization and
bread crumb hardness were then measured. In each case, bread produced by the
straight dough method was found to be superior to bread made using the sponge
dough method.
