Effect of Reducing Fat and Using Fat Replacers in the Crust of Flaky Chinese Pastry

Abstract

Flaky Chinese pastry (Pia), is a small Chinese pastry filled with mungbean conserve and is a popular bakery product. Its crust is made from wheat flour, fat, water, sugar and salt, with mungbean conserve stuffed inside. This research aimed to lower the fat content in Pia by using fat replacers in the outer crust that had high liking scores from untrained panelists. Maltodextrin gel and inulin gel were used as fat replacers. The results indicated that the hardness of the product increased slightly with the reduction in fat content, while the extension and puffiness decreased. Panelists liked products in which the fat content in the outer crust was reduced by 45% and replaced by 50% of its weight with inulin gel in the formula. The overall liking of the developed product was at a moderate level, which was not significantly (p > 0.05) different from the control. The chemical composition of this formula was analyzed and showed that the fat, total calories and calories from fat could be reduced by 10.5, 3.02 and 10.05%, respectively.
