This causes poor noodle quality and greater loss during packaging and distribution. The introduction of vacuum mixers in some plants has overcome this problem. Aging the dough before sheeting is beneficial in all noodle production. It improves starch gelatinization and assists in the even hydration of the flour

The added benefit is a smoother noodle surface and associated decreased stickiness both of which are desired by the consumer. During the compression stage of sheeting the gluten initially is developed and becomes more uniform in nature. 24 However, in most small commercial plants a dough-resting or aging step is not used, resulting in uneven hydration and subsequent loss of gluten development. Random areas of poor gluten development result in weak areas within the cut noodle causing increased loss during subsequent packaging and distribution. Compound sheeting using waved rollers, see Fig. 7.2, in a multi-roller system, has been regarded as a significant development in noodle production. 23 The primary goal of this system is to improve the development of the gluten network to achieve noodle quality approaching that of the hand-made noodle. 7.3 White salted noodles 7.3.1 Hand-made noodles Three forms of noodle making by hand have been used traditionally: hand swung, hand cut and hand stretched. Hand-swung noodles have great appeal as they are considered the optimum noodle quality. Flour and water (55 percent) containing dissolved salts are mixed to form a crumbly dough. Intensive hand labor kneads the dough to develop the gluten. The dough is then rolled into a rope whose ends are held in either hand. Repeated swinging elongates the dough which is folded and twisted and the process repeated. With each elongation the
