Educational Goals

The course aims to achieve the following learning outcomes for students:

  • Acquiring knowledge in the basic physical principles that govern the physical processes during food production and in particular real fluid dynamics, thermodynamics of real gases with irreversible thermodynamic cycles, and mass and energy balances in food engineering with applications in fruit and vegetable preservation technology and freezing technology in food processing industry.
  • Application of Physics in the food industry in the form of computational exercises.

General Skills

  • Analyzing, interpreting and synthesizing special topics in Physics and their applications in food industry. Searching and analyzing information using measurements of physical quantities obtained from experimental studies.
  • Promotion of analytical, creative and inductive thinking.
  • Decision-making.
  • Autonomous work.
  • Teamwork.

Teaching Methods

Face to face:

  • Lectures (theory and exercises) in the classroom.

Use of ICT means

  • Lectures with PowerPoint slides using PC and projector.
  • Notes, solved and unsolved problems in electronic format. Each session involved both a faculty lecture and student participation in problem-solving exercises.
  • Posting course material and communicating with students on the Moodle online platform.

Students Evaluation

Evaluation methods:

  • Attendance at class and participation in discussions, and solving exercises in the classroom is rewarded with 20% of the final grade.
  • Written final exams (80% of the final grade).

The evaluation criteria are presented and analyzed to the students at the beginning of the semester and are available at the course website.
