This course unit goes through the procedures and unit operations used in the food industry to preserve and transform raw materials in food, given the specificity of these industries and methodologies to ensure quality and food safety. In addition, it addresses "packaging" in its different forms as inevitable and indispensable in the markets and modern life. Packaging is virtually present in all products, whatever their degree of freshness, its geographic market and market dimension. Packaging is part and contributes to the 'product identity', not only because it reveals the product to the consumer, but mainly because the product characteristics depend on the characteristics and features of the package.

At end of this course each student shall be able to evaluate procedures and unit operations used in the food industry in terms of preservation and transformation of raw materials in food, given the specificity of these industries and methodologies to ensure quality and food safety, with particular attention to features, applications and production methods of various types of packaging used in the food sector

1. Introduction
2. Traditional methods
3. Processing: kinetics of thermal degradation of physic chemical and microbiological tests on food; heat transfer; processes by application of heat; bleaching; pasteurization, sterilization; distillation and evaporation; extrusion; drying and dehydration; baking and roasting; frying; heat removal processes; membrane separation; extraction

Blended learning

Evaluation is made on individual basis and it involves the coexistence of two modes: continuous assessment (60%) and final evaluation (40%). Further information is detailed in the Learning Agreement of the course unit.
