Fried foods usually contain a significant amount of saturated and unsaturated fats, in some cases up
to 1/3 of the total product mass. This high fats content has been related to obesity and coronary heart
diseases. During deep-frying, the internal moisture of food is evaporated while oil is confined to the
external surface. These processes are influenced by factors such as oil quality, frying conditions
(temperature and time), food composition and pre-frying treatments (blanching and/or drying). The
increase in the consumer’s interest for more healthy food products has led to the trend of reducing lipid
uptake in fried-food products while maintaining acceptable organoleptic characteristics. Edible coatings
prepared from food hydrocolloids, such as cellulose and derivatives, gums, alginate, whey protein,
albumin or pectins have been studied for such purpose. The high water absorption capacity and retention of the original food firmness of these coatings decrease the moisture loss by evaporation, reducing lipid
uptake [56].
