The course is intended to introduce students to the issues comprising experimental observation of the reactions important in food technology, laboratory and practice. Students will learn how to control reactions and describe them by the use of kinetic means.

To get credits, students have to complete all the exercises prepared for particular run and submit the relevant protocols. In the case of an absence with leave, the exercise will be performed in a reserve time slot. In the case of long-time absence for a serious reason - a disease lasting more than one third of the laboratory run duration - the student may be exempted from one exercise. For credit acquisition, successful completion of the final test, which includes questions on the principles of the reactions observed in the exercises, relevant calculations and kinetic relationships, is needed.
