  • Home preparation for classes - 30 hours per semester
Learning outcomes
The goal of the course is to summarize theoretical and practical knowledge of chemistry and technology of lipids. Attention is paid to the topics dealing with lipid composition, raw materials, technological processing and practical application.
After completion of the course, students have fundamental knowledge about the composition, extraction and processing of fats and oils. They are informed about modification procedures of fats and oils and their commonn use, with emphasis on their applications in food processing industry and cosmetics.
Prerequisites
Basic knowledge of inorganic and organic chemistry and biochemistry.

Assessment methods and criteria
Grade (Using a grade system), Oral examination, Written examination

Attendance: mandatory at the first lecture and at all laboratory exercises. Course credit: attendance at all laboratory exercises, submitted protocols that all meet teacher's evaluation. Examination: written test covering entire curriculum scope. Oral examination. The result of a subject examination is expressed on a six-point scale: A "výborně" (i.e. "excellent"), B "velmi dobře" (i.e. "very good"), C "dobře" (i.e. "good"), D "uspokojivě" (i.e. "satisfactory"), E "dostatečně" (i.e. "sufficient"), F "nedostatečně" (i.e. "fail").
