Milk processing on family farm (188842)

Nositelj predmeta

Opis predmeta

Milk processing could be a significant business activity of many family farms. Milk processing could make the majority of the farms' profit. Problems of milk collecting are solved by milk processing on family farms, especially in areas where milk collecting is difficult and expensive (for instance in the Mediterranean islands and mountains’ areas). Moreover, milk processing increases profit per farm due to the additional employment of family farm members which are involved in activities of milk production, processing and selling of dairy products. By higher profit per farm, depopulation of rural areas is avoided, as well as, protection of traditional dairy products is ensured. It is well known that Croatia is a country rich in such products that are still produced on small family farms. Through this course student’s acquire basic knowledge about production of high quality milk on family farms which is crucial for production of the high quality traditional dairy products. Students will receive knowledge about treatment of milk after milking and knowledge about milk processing into different traditional dairy products. Moreover, the course will cover the basic requirements for building, adaption and equipment of small scale dairy plants, labeling of dairy products, hygiene and sanitation, hygiene indicators, introduction of guidelines for good hygienic practice and implementation of HACCP principles, traceability and safety, sensory evaluation, direct selling and the protection of dairy products. Students will be introduced to traditional Croatian dairy products through seminars.

Obveze nastavnika

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 from the course subject. 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.

Obveze studenta

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.
