Fat reduction in food is a major concern in our days, as market
demands increase for lower fat products. This is related to indices
showing a duplication of the population with overweight and
obesity in the last 30 years, accounting in 2008 more than 1400
million adults (WHO, 2014). Obesity may be related to other noncommunicable
diseases (Grundy, 2004). Fat substitution by other
ingredients is a great challenge, with special focus in bakery
products, as they can contain elevated levels of fat.
Pound cakes are consumed everywhere, and can contain up to
17 g/100 g fat in the product. Fat provides several advantages to
pound cakes, such as higher volume and softness in the final
product, due to a higher air incorporation during batter preparation
and inhibition of gas-bubble coalescence, leading to a finer and
softer crumb structure
