SUSTAINABILITY OF POWDERED MATERIALS FROM FARM TO FORK

The requirements for faster product development cycles, lower product cost and environmental sustainability are ever increasing in today’s globally competitive market. Cleaner production and sustainability are of crucial importance in the field of manufacturing processes where great amounts of energy and materials are being consumed. In Food technology and production there are a lot of new technologies that enables products with changed basic nature of material and they have constantly been studied. To observe new technologies, like nanotechnology, one has to be familiar with basic properties of those materials in a raw state as well as in finished products. Majority of materials are in a powdered, grained or granulated form during the process of food product formation. Their properties and quality characteristics are investigated while they are presented from farm to storage silos, from production chain to table. They have to be grinned or mixed for formulation or nutritional reasons. They show different properties before and after they have been processed (extrusion, thermal treatment). It is essential to know their physical, rheological, geometrical, behavioural and sensorial properties. Powders behave the way no other materials, that’s the reason why their characterisation is necessary for every new production application. Powder manufacturing technologies allow us to manufacture products with high quality values according to consumers needs. They put a great pressure on food industry to create products with added values, good texture, new taste or smell and at the same time with a reasonable price. For that reason industry sector collaborates closely to research institutions. Insofar as environmental considerations become an important issue in our society, as well as legislation obligations, those processes have to be evaluated in order to make easier its acceptance in the industrial world. Therefore there is a constant need to evaluate the risks of novel properties of raw materials to ensure their safe production, handling, use, and disposal.
