Method of making bread

1. A method of making bread, comprising:

a thermally treated dough making process of forming a thermally treated dough through a milk/salt heating step of heating a mixture of 48 to 50% of milk and 1 to 2% of salt to 95° C., a wheat flour addition step of adding 48 to 50% of wheat flour to the heated mixture, an aeration step of aerating and stirring the mixture, a low-temperature ripening step of ripening the aerated mixture in a refrigerator for 14 to 16 hours to form a thermally treated dough;

a dough mixing process of mixing the thermally treated dough of the thermally treated dough making process with wheat flour, dried yeast, refined sugar, refined salt, whole milk powder, bread improver, processed butter, milk, egg, and water to form a dough mixture, and stirring the dough mixture;

a deep-freezing process of dividing the dough mixture into equal-sized dough pieces and deep-freezing the divided dough pieces at −38° C. for 40 minutes;

a thawing process comprising a low-temperature thawing step of primarily thawing the deep-frozen dough pieces at 5° C. for about 16 hours followed by a room-temperature thawing step of secondarily thawing the dough pieces at 25° C. for 2 hours;

a fermentation process in which the thawed dough is placed in a bread pan to be fermented; and

a baking process in which the fermented dough is heated.
