Food of aniimal and plant origin

A.Y. 2020/2021
Overall hours
AGR/03 AGR/19
Learning objectives
The course aims to introduce the physiology of animal and fresh vegetable product, in relation to its food features. It aims to provide scientific basis on biochemical and physical changes that occur during ripening, postharvest evolution and the factors related to qualitative and quantitative losses, including those for biochemical, pathological and physiological spoilage. The course deals with the commercial procedures for harvesting, processing, storage and marketing that are best suited to the products. It provides knowledge on technologies for the preservation of the freshness and qualitative analysis. Moreover, the course provides the understanding of the main characteristics of animal products (milk and dairy products, meat and meat products, fish) by providing knowledge on zootechnical factors that affect quality and production of these products.
Expected learning outcomes
At the end of the course the student will achieve the skills necessary to distinguish the main qualitative characteristics of food. The skills will enable the professional management of fresh fruit and vegetables in order to safeguard their quality, freshness and safety and to optimize their transformation into high quality products. It also provides the knowledge of the typical and excellent Italian fruit and vegetable product in order to protect its value. The student will be able to make a careful choice of products of animal origin offered by the market also in relation to production methods.
Course syllabus and organization

Single session

Lesson period
First semester
The lessons will be held on the Microsoft Teams platform and can be followed in synchrony on the basis of the first semester schedule.
Some lessons, situation permitting, will be in attendance. The methods and criteria for participating in face-to-face lessons, which for a reservation with a special app, will be published in time on the Ariel pages of the course, as well as notices relating to any update related to the evolution of the Covid-19 regulation.
The program and reference material will not be affected
The exam will take place in oral form using the Microsoft Teams platform or, where the regulation allows it, in person, always in written form.
Prerequisites for admission
No prerequisites
Assessment methods and Criteria
The assessment of the effective learning of the contents and topics covered in the lessons of the course takes place by means of an oral test.
The following topics, regarding the module of food of vegetable origin, will be subject of the test: knowledge of the physiological processes that play a role in determining the deterioration of plant products, in particular fruits and vegetables, and the factors that influence these processes; moreover, the understanding of all the procedures and technologies used in post-harvest to preserve and maintain the quality of plant products, and analytical approaches and methods for assessing quality attributes will be assessed.
As regards the module of food of animal origin, it will be ascertained the knowledge of the main husbandry techniques to produce, monitor and improve, from a qualitative-quantitative and hygienic-sanitary point of view, the final product of livestock farms, such as milk, fermented milk, butter, cheeses, beef and pork, and meat products.
The evaluation is expressed by thirtieths, resulting from the mathematical average of the grades obtained in the 2 single modules, approximated to the unit.
To take the exam it is necessary to register within the deadline set on the SIFA.
The grade is communicated to each individual student by e-mail automated by the University's verbalization system.
