Caracterização do composto residual obtido no processamento da batata frita

Abstract

The potato (Solanum tuberosum L.) plant with a certain characteristic is that the underground stem called a tuber, which is the edible part, considered a vegetable of great economic importance in Brazil. Generally marketed in fresh form, easily prepared for consumption in the form of puree, crisp type chips or straw, but is also marketed in processed forms such as: potato chips or frozen pre-fried frozen, peeled cooled and others. This tuber originating in the Peruvian Andes and Bolivian ended up winning the world taken by Spanish colonizers introduced in Europe where Spain and Ireland were the first countries to stand out in your planting, eventually spreading around the world and is currently the fourth most consumed food grown over 136 countries and would be no different in Brazil, where among the greenery is considered the main. Today in Brazil the species are cultivated Achat, Bintje, Monalisa, and Aracy Rados, the Bintje and those who have favored both cultivation and to be used in the production of potato chips and french fries. The potato has in its composition carbohydrates, protein, vitamin C, vitamin B complex, and a good source of iron, phosphorus and potassium. The processing of potatoes to produce potato chips and straw, begins in the choice and quality of it, goes through a washing, peeling, cutting, frying and packaging. The subject matter of this work, residual starch, has its origin in the stage of peeling and cutting potatoes, considered the disposal on the production line is usually deposited in a lake of contention, because the industry has no commercial value, so considered a disposal, but this reality is changing, in the so-called cycle of use disposal of potatoes, both the liquid (starch) and the solid (shell) are being recycled and transformed into biodegradable products. Starch is reused to produce alcohol (ethanol), and alternative fuel industry, in the mixture with plasticizers and polymers, production of plastic bags environmentally friendly, gas production in biodigesters; ironing fabrics in more natural process. Finally, one can say that considering the results obtained in experimental procedures, that the disposal of potatoes is usable, the starch in the potato waste, by the way a considerable amount, makes it viable raw material for production of both alcohol and other products.
