20150056328 | PREPARATION AND THE USE OF FROZEN DOUGH FOR MICROWAVABLE FRIED FRITTERS - It relates to the manufacturing and preparation of frozen dough, and its application in microwaveable fried food. The preparation of fried fritters comprises the following steps: disposal of raw materials, dough kneading, dough proofing for the first time, dough folding, dough proofing for the second time, making blanks, frying and quick-freezing. Alum as the acidic component in leavening agents is replaced by a complex formulation of gluconic acid-δ-lactone, glycerol monolaurate and calcium dihydrogen phosphate, thus reducing the toxicity of the dough. The fried fritters preparing by the dough of the present invention possess a good expansion rate, crispness and taste, and should satisfy consumer demands for quality food products that can be reheated by microwaving. | 02-26-2015 |
