PROCESS AND SENSORY EVALUATION OF FOOD

Academic Year 2022/2023 - Teacher: Giuseppe MURATORE

Expected Learning Outcomes

The course aims to provide the student with the main knowledge related to the processes of conservation and transformation of the products of the main agri-food chains intended for human nutrition, learning the technologies of the related production processes that lead from raw materials to the product.

At the end of the course students will have developed the skills necessary to understand the relationship between technological conditions adopted for production and quality characteristics of the food product and will be able to analyze the processes of food technology to identify the critical issues and intervention actions to ensure the quality of finished products.

Course Structure

Lectures (35 hours - 5 CFU) and exercises (14 hours - 1 CFU) (classroom and company), also on line

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the Syllabus.

Learning assessment may also be carried out on line, should the conditions require it.

Information for students with disabilities and/or DSA. As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Inclusion - Services for Disabilities and/or DSAs), in the persons of professors Giovanna Tropea Garzia and Anna De Angelis.

Required Prerequisites

Basic knowledge of chemistry and microbiology

Learning Assessment

Learning Assessment Procedures

The assessment of learning takes place through an oral interview. The evaluation of the student's preparation will take place on the basis of the following criteria: learning ability and level of depth of the topics covered, synthesis and exposure properties, and the student's reasoning skills.

The vote follows the following pattern:

Knowledge and understanding topic: Important shortcomings. Significant inaccuracies

Analysis and synthesis skills: Irrelevant. Frequent generalizations. Inability to synthesize

Use of references: Completely inappropriate

18-20

Knowledge and understanding of the subject: At the threshold level. Obvious imperfections

Analysis and synthesis skills: Just enough skills

Use of references: Just appropriate

21-23

Knowledge and understanding of the topic: Routine knowledge Analysis and synthesis skills: It is able to correct analysis and synthesis. Argue logically and consistently

Use of references: Use standard references

24-26
