Chemistry of deep-fat frying oils
WebFood absorbs varying amounts of oil during deep fat frying. Sizable amounts of oil/fat are carried with the food – 5 to 40% by weight, e.g. potato chips have a final fat content of about 35% resulting in need for addition of fresh oil. Food itself can release some of its endogenous lipids into frying oil/fat. • e.g. fat from chicken. WebThe physico-chemical changes of product which occur during frying influence the thermal conductivity at these regions. In the core region, the starch gelatinization, taking place during the first minutes of frying (3 min), causes an increase in core thermal conductivity; while the moisture loss which starts after 3 min of frying decreases ...
