Effect of batter formulation on lipid uptake during frying and lipid fraction of frozen battered squid
The present paper studies the influence that batter ingredients (wheat flour, corn flour, salt and leavening agent) have on fat content and oxidative degradation of the lipid fraction of deep-fried frozen battered squid. The use of a leavening agent significantly increases the fat content during frying; the generation of gas cells where oil easily lodges is the most important event observed by scanning electron microscopy when this additive is used in the formulation. The addition of salt in the formulation also increases fat content, but replacement of wheat flour by corn flour decreases significantly the oil content of the battered squids. The acidity index values indicate a relatively low degree of hydrolysis for all the batters studied. The batter formulation influences the degree of oxidation of the lipid fraction of the deep-fried products; the battered product with leavening in its formulation shows a lesser oxidation (P<0.05), which might be connected with the high absorption of oil during deep fat frying.

| Summary: | The present paper studies the influence that batter ingredients (wheat flour, corn flour, salt and leavening agent) have on fat content and oxidative degradation of the lipid fraction of deep-fried frozen battered squid. The use of a leavening agent significantly increases the fat content during frying; the generation of gas cells where oil easily lodges is the most important event observed by scanning electron microscopy when this additive is used in the formulation. The addition of salt in the formulation also increases fat content, but replacement of wheat flour by corn flour decreases significantly the oil content of the battered squids. The acidity index values indicate a relatively low degree of hydrolysis for all the batters studied. The batter formulation influences the degree of oxidation of the lipid fraction of the deep-fried products; the battered product with leavening in its formulation shows a lesser oxidation (P<0.05), which might be connected with the high absorption of oil during deep fat frying. |
