Abstract
Abstract Preparation of a wheat flour pasta by preparing a dough, shaping the dough into individual pasta pieces, pre-drying the pieces to a moisture content between 22 and 27 per cent by utilizing warm dry air and then drying the pasta to between 8 and 13 per cent moisture by application of microwave energy. The use of microwave energy materially reduces the overall drying time and produces a pasta with a shortened rehydrating time and less microbiological buildup.
