The risk of cardiovascular disease, type-2 diabetes and colorectal
cancer increases with obesity. Diet and lifestyle can be modified to
prevent and reduce the risks of these diseases. There is epidemiological
evidence that diets that promote health are rich in dietary
fiber and omega-3 fatty acid and low in saturated fat, trans fat and
cholesterol (Hu, 2002). A strategy to reduce the consumption of fat
is to develop products with low fat content. Fat is one of the substances
that is used more frequently in bakery products (Quaglia,
1991). Fat salter the sensory characteristics of bread and fermented
products, providing a shorter and smoother bite and
increasing the shelf life and duration of their softness. These effects
are intensified as increasing amounts of fat are added. According to
Brien, Mueller, Scannell, and Arendt (2003), the production of
breads with a lower fat content that possess the quality characteristics
derived from the functional properties of fats, such as a
greater volume, smoother texture and delayed aging, is a technical
challenge for food technologists. Based on concerns for health and
for foods with specific features that improve health, there has been
an increasing interest in so-called functional foods, which are
consumed as part of the usual diet and which either provide
physiological benefits or reduce the risk of chronic disease beyond
the basic nutritional requirements (Shahidi, 2009).
