At the end of this course the student will have acquired knowledge, skills and powers to:

1-    At the technological level, develop interpretation and analysis capabilities and acquire skills in the production and agro-industrial processing.

2-    At the production level, understand and develop technical itineraries, considering the operational plans of agricultural enterprises.

3-    At the processing level, understand the articulation of the different unit operations related to food, continuous and discontinuous, applying fundamental concepts and methodologies in the agro-industrial.

4-    Articulate and develop technological procedures for the development of new food products.


General knowledge regarding food production and processing, with emphasis on unit operations involving the organization of production and processing flowcharts.
