Cheesemaking (176007)

Course coordinator

Course description

Students are introduced to cheesemaking history, cheese definitions and classifications. In this module cheesemaking technology is postulated which starts with the milk selection and its preparation for renneting. These technological steps include milk analysis from the point of milk delivery to the cheesery, removing the mechanical waste, standardisation of the milk for cheesemaking, pasteurisation and the addition of additives and starter cultures in milk for cheesemaking before renneting. The fundamental chemical-biochemical mechanism of renneting is described. Furthermore, general rules for curd treatment is described, cheese moulding and salting in the production of different types of cheeses (fresh, soft, semi hard, hard and extra hard). This module provides general information about ripening and packaging of cheese. Knowledge about hygiene and sanitation in cheesemaking is also covered as well as the implementation of HACCP. This module provides information about the environmental protection during building, reconstruction, designing, and equipping of the cheese making plant. During the practical part of the module (exercises) students are introduced to the business organisation in a cheesemaking plant which includes calculations in the production and dealing of by-products that appear during cheesemaking such as cream, butter and whey (for instance albumin cheese – ricotta). During the laboratory practical work students are introduced to fundamental cheese analysis essential for cheese labelling. Field working includes practical work in the cheesemaking units (three different dairy plants) from milk receiving till packaging of the final products as well as cleaning maintenance of the production units. Students are introduced to the most world famous cheeses through seminars. Each student presents characteristics of a particular cheese in front of the group.

Working methods

Teachers' obligations

Lectures
The lecturer of an individual unit should organize the lectures as a power point presentation with the time provided for interactive teaching. Lectures of teaching units that cover the subject should be organized according to the timeschedule and held within 15 weeks of direct teaching. All teaching materials that are not contained in the textbook are organized by teachers and according to teaching units available in the MOODLE system.

Seminars
Seminars are organized and conducted by a teacher on the subject in order to supplement and expand the knowledge of the cheesmaking. The topics of seminar papers must be given to the students at the beginning of the semester and provide them with 10 weeks of preparation. The teacher gives instructions on how to create seminar papers, approaches to scientific literature and databases, useful links, and helps students (provides guidance) during the seminar work. The teacher organizes oral presentation of the seminar papers, actively participates in the discussion together with other students. The overall quality of the seminar work (oral presentation and power point presentation) is evaluated by the teachers with the grade that participate in the final grade.

Auditing and field exercises
The subject teacher should organize the lectures from the auditing exercises as a power point presentation with the time provided for interactive teaching. Field exercises are organized by the subject teacher with the aim of presenting practical work in medium and large scale dairy plants.

Forum for communicating with students; a calendar of important events for the course; information related to the course; the instructions for writing the seminar work and results of written exams are available in the MOODLE system.

Students' obligations

Attending lectures, exercises and seminars is mandatory. In cases of justified or unjustified absence from the lectures and/or exercises and/or seminars, students are obliged to enclose a report stating the reason of the absence, during the semester or within 4 weeks after the end of the semester. In case of the absence of more than 20%, students lose the right of signature, and the subject must be re-enrolled in the next academic year. The obligation of each student is to make a seminar paper and present the topic discussed in the power point presentation (in 10-15 minutes) after which other students and teacher have the right to ask questions. The written part of the exam that is organized within the regular examination period or during the semester students can take written part of exam as two partial written exams. Oral exam is organized during regular examination period.
