Reaproveitamento do permeado do soro de leite

Abstract

Brazil is currently the fourth largest milk producer in the world, behind only for United States, India and China. It is linked to the large amount of effluent generated by the dairy factories, increasing the need to reuse products such as milk whey which is often devalued or discarded by these industries. The permeate is a by-product obtained by the process of the whey ultrafiltration, being rich in lactose, minerals and water. Therefore is a product of high nutritional value with numerous possibilities of reutilization. The aim of the project work is to present a bibliographical review about what is the permeate and where it comes from, mainly covering the forms of valorization of the same, that can be used in obtaining products and raw materials, as a consequence to minimize the disposal, reducing treatment costs and the environmental impact generated by the inadequate disposal of this effluent. A dairy industry produces about eleven liters of effluent per liter of processed milk, this effluent brings with it high load of COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand). Several papers showing the numerous uses of the permeate, such as obtaining oligosaccharides that are widely incorporated into food and pharmacy production. Basically you only have to contribute to avoid waste of such a rich product. As mentioned, the alternatives for the reuse of the permeate are vast when adding it in the manufacture of new commodities the catalog of options offered by the company is increased and the consumer market is extended, as result it only has to add.
