Learning outcomes
The aim of this course is to supply the knowledge of the main operations to put into effect on the raw materials and on the semifinisched to the production of the foods: Operations of separations: filtration, sedimentation, flotation, centrifugation, pressing. Distillation: equilibrium curves, simple and split distillation. Food conservation and stabilisation: physical and chimicals methods. Heat treatments: concentration, evaporation, drying, liophilisation, pateurisation and sterilisation. Low temperatures tratments: refrigeration, freezing, deep-freezing. At the end of the course, the student will have knowledge on the production of different types of wine (white, red, sparkling and dessert wine) and spirits (brandy, cognac, armagnac, grappa). They are also given notions about technology of beer.
Course contents
Preliminary operations. Operations of separations: filtration, sedimentation, flotation, centrifugation, pressing. Distillation: equilibrium curves, simple and split distillation. Food conservation and stabilization: physical and chemical methods. Heat treatments: concentration, evaporation, drying, lyophilisation, pasteurization and sterilization. Low temperature treatments: refrigeration, freezing, deep-freezing. At the end of the course, the student will have knowledge on the production of different types of wine (white, red, sparkling and dessert wine) and spirits (brandy, cognac, Armagnac, grappa). Moreover, notions on beer, whisky, cider, calvados and rum will be acquired.
