Water is an essential component of almost all of the foods that we consume, yet its presence may pass largely unnoticed. We derive considerable quantities of the water that we need to sustain our lives from this ‘hidden’ water in foods. The original idea for this book came from the running of seminars on water activity in bakery products. Much is known about the contribution of water …
Antioxidant activity depends on many factors such as the lipid composition, antioxidant concentration, temperature, oxygen pressure, and the presence of other antioxidants and many common food components, e.g. proteins and water. Antioxidants were first used before World War II for food preservation. These early antioxidants were natural substances. They were, however, soon replaced by synthet…
