Micro-sugar-snap and -wire-cut cookie baking with trans- and zero-trans-fat shortenings. Cereal Chemistry. 87:415-419. Interpretive Summary: The two AACC micro-cookie-baking methods were used to evaluate the effect of trans- and zero-trans-fat shortenings on cookie-baking performance. For both fat shortenings, sugar-snap cookies made with a given flour were larger in diameter, smaller in height, and greater in weight loss during baking than were corresponding wire-cut cookies. Differences in fat type (trans vs zero-trans) did not significantly affect the geometry of sugar-snap cookies, but did affect that for wire-cut cookies. Of the two baking methods, wire-cut cookie baking showed a much more sensitive response to changing ingredients, compared with sugar-snap cookie baking. Our overall results thus confirmed that wire-cut cookie baking is a better diagnostic tool for use in evaluating ingredient changes in cookie formulas. When the wire-cut cookie-baking method is used for analyzing the cookie-baking quality of soft wheat flours, and in particular, for comparing the baking performance of a comprehensive set of flour samples, use of consistent ingredients and procedures is also necessary, in order to obtain reliable results. Technical Abstract: The effect of trans- and zero-trans-fat shortenings on cookie-baking performance was evaluated, using the two AACC micro-cookie-baking methods. Regardless of fat type, sugar-snap cookies made with a given flour were larger in diameter, smaller in height, and greater in weight loss during baking than were corresponding wire-cut cookies. Differences in fat type (trans vs zero-trans) did not significantly affect the geometry of sugar-snap cookies, but did affect that for wire-cut cookies. In the wire-cut cookie-baking method, cookies made with zero-trans-fat shortening produced larger diameters, smaller heights, and greater weight loss during baking than did those made with trans-fat shortening. Of the two baking methods, wire-cut cookie baking showed a much more sensitive response to this ingredient change, compared to sugar-snap cookie baking. Ouroverall results demonstrate that wire-cut cookie baking is a better diagnostic tool for use in evaluating such ingredient changes in cookie formulas. |
