A.Y. 2024/2025
Learning objectives
General aims:
The Course is divided into four teaching units and has the main objective of illustrating to students, through general concepts and analytical technologies, some paradigmatic examples relating to the impact of environmental stress on food-producing animals, with reflections on the biological dynamics and the relationship between parasites and their respective hosts, and on the food assessment processes.
Aims of the Teaching Units:
TEACHING UNIT: "Host-parasite dynamics in a changing environment"
The Unit aims to provide a comprehensive view of the effects of environmental changes on host-parasite relationships assuming a well known food-producing animal, the honeybee, as a reference model for sustainable, environmental-driven livestock production.
TEACHING UNIT: "Authenticity and quality issues in animal food products"
The Unit aim is to provide student knowledge in analytical techniques for food authenticity and quality.
TEACHING UNIT: "Environmental proteomics"
The unit aims to understand how organisms respond to environmental stress at the molecular level through an integrated omic approach. The course provides examples of proteomic approaches to study changes in protein abundance and post-translational modifications in response to environmental stressors.
TEACHING UNIT: " High Resolution Mass Spectrometry approaches toward environmental risks detection involved in food safety "
The Unit aims to provide the main knowledge in the field of inspections in relation to the Community reference standards and national transpositions (National Residual Plan) for quality analysis, certification, fraud and food safety in production chains of food of animal origin. The course provides the theoretical bases and practical applications of the main new techniques to protect food safety along food chain of food of animal origin
