This new Second edition of Bread Making: Improving Quality is an essential handbook for the bakery technologist and for other professionals in the bread making industry.

Part 1 addresses the impacts of wheat and flour quality on bread, covering topics such as wheat chemistry, wheat starch structure, grain quality assessment, milling and wheat breeding.

Part 2 covers dough development and bread ingredients, with chapters on dough aeration and rheology, the use of redox agents and enzymes in breadmaking and water control, among other topics.

Part 3   focuses on bread sensory quality, shelf life and safety. Topics covered include bread aroma, staling and contamination.

Part 4 covers bread products such as high fibre breads, those made from partially baked and frozen dough and those made from non-wheat flours.
