Potato processing cutting

Starch Sweet potato has the advantage of remaining as a high starch-producing crop with 30 and 49% greater starch yield than rice, corn, or wheat, respectively, under the same conditions. In China, at the former level process, sweet potatoes are cut up by hand, crushed by machine, and sieved to remove waster such as peel and fiber. The starch is left to settle in a tank and then removed. Water is added to the starch, which is once more sieved and settled. Wet starch is transferred to jute bags and allowed to drip-dry for 1 d, and air-dried outside at ambient temperatures [25]. 

In addition, fhiit and vegetables can be minimally processed (washed, pealed, cut, diced, stripped, chopped, etc.) in order to provide ready to eat or ready to use products (salad mixes, apple slices, carrot sticks, diced potatoes, etc.). These minimal processing treatments damage the plant surface and induce changes in phenolic metabolism and phenolic antioxidant composition. 

Sources. The best food sources of vitamin C are citrus fruits, berries, melons, tomatoes, potatoes, green peppers, and leafy green vegetables. Vitamin C is sensitive to air, heat, and water, so it can easily be destroyed by prolonged storage, overcooking, and processing of foods. It is also present in some cuts of meat, especially liver. 

Most of fruits and vegetables are cut into pieces before they are contacted with hypertonic solution. Shape and size of the material pronouncedly affect the rate of the process. Osmosed fruits and vegetables have different forms that come from the technology and consumer requirements [62,63], Plums were dehydrated in whole or in halves [64] apples were cutinto 12 segments [65,66] or sliced into 3 mm slices [67] or 3-4 mm thick [15]. Peaches were cut into 6 or 8 segments and pears into 8 segments [65]. Carrots were cut into cubes of 5 or 10 mm [68,69], Potatoes were sliced 5 and 10 mm thick [70], or diced [20], Papaya was cut into cubes. 

During the First World War, Germany s powder plants were barely able to produce the amount of munitions required. A major problem arose from the lack of raw materials and components. Germany had no natural deposits of some of the materials, and was cut off from suppliers. Therefore, it had to find substitutes and synthetic processes, of which the Haber-Bosch process is perhaps the most famous. For example, Germany used coal for the production of toluol and phenol, and potatoes for the production of alcohol. Saltpetre — an essential raw material for the production of explosives — was not naturally available in Germany, and had to be imported. During the war the lack of saltpetre became a major constraint on German munitions production.
