Postharvest physiology and quality of horticultural commodities
Code: G-00S-
Teacher:  Ilaria Mignani
Year:   
Term: 
CFU: 
CFU subdivision: Lectures: 4
Basic aims:  The main topic of the class is to understand the fisological, biochemical, and phisical processes during the postharvest life of produces.
Acquired skills:  The "Postharvest physiology and quality of horticultural commodities" class offers the skills to be able to manage fresh produces with the best quality and food safety.
Course contents:  Postharvest losses in horticultural commodities. Biological aspects –composition, nutritive value, structure, morphology, growth and development- of pome, stone, soft fruits, grapes, citrus and leaf, fruit, stem, root, tuber vegetables, ornamentals and cut flowers.
Program:  GENERAL BIOLOGICAL CONSIDERATIONS: Postharvest losses in horticultural commodities. Biological aspects –composition, nutritive value, structure, morphology, growth and development- of pome, stone, soft fruits, grapes, citrus and leaf, fruit, stem, root, tuber vegetables, ornamentals and cut flowers. RIPENING PHYSIOLOGY Respiration: definitions, characterisation of process, measurements, factors affecting, comparative rates, biological significance;Traspiration: definitions, characterisation of process, measurements, factors affecting, comparative rates, biological significance;Role of plant hormones in senescence. Ethylene and fruit ripening: biosynthesis, factors affecting production rate;Physiological disorders: symptoms and causes;Pathological diseases: host-parasite-environmental relationship, infection processes, disease control methods. COMPOSITION AND QUALITY:Compositional changes: carbohydrates, organic acids, pectic substances, lipids, aminoacid, protein, phenolics, mineral content, pigments, vitamins.Quality and its components. COMMERCIAL PRACTICES AND PROCEDURES. Maturity and quality standards, standardisation and inspection.
