Program

Theoretical: Horticultural products for direct consumption (cooling process, controlled atmosphere, postharvest physiological Diseases); Minimally Processed products (processing Steps; Changes of plant tissue; Advantages and disadvantages); Manufacturing technology of frozen peas; Manufacturing technology of canned peach; Tea Technology (green and black); Technology of manufacture of nonalcoholic drinks; Sugar Technology (from beet and from sugar cane); Technology of oils and fats of vegetable origin (Physical and chemical properties of lipids with technological importance, manufacturing operations, olive oil Technology); Technology of cereals (pasta; Bakery; Downgrading of starch). Practice: quality control of frozen vegetables: search for peroxidase activity. Quality control of a canned fruit: stove proof and sterility test. The effect of ascorbic acid, cysteine and salt on viscoelasticity of bread dough.

Teaching Methodologies

The teaching is based on three fundamental pillars, lectures, practical classes and laboratory activities. The lectures are organized by themes, and consist mainly by theoretical exposure of fundamental concepts of technology post-harvest. An important component of education is based on discussion with students, who are encouraged to develop reasoning clearly focus on industry problems solving. The laboratory classes are made individually or in groups and results obtained from the practical work are used for the calculation of, for example, kinetic of vegetal enzymes inactivation during the bleaching.
