PārZB012 [GPARB012] Fruit and Vegetable Processing II
Students obtain the knowledge about fruit and berry processing and about physical, biochemical and microbiological processes during production of these products. They also get information about defects of fruit and berry products and possibilities to avoid them.
After the finishing of this study course students will obtain the following learning outcomes:
knowledge about fruit and berry preservation methods, about processing principles of different fruit and berry products, and about physical, biochemical and microbiological processes during production of these products;
skills to evaluate the quality parameters of fruits and berries and their processing products (physical, chemical, etc.), to lead and control the technological processes of different fruit processing products;
competence to analyse and explain the physical, biochemical and microbiological processes during production of different fruit and berry products.
1. Fruit berry compotes. Fruit berry jams and purees. 1. laboratory work – Preparation of apple compote (preparation, pasteurization) and quality assessment. (Lecture - 1h; laboratory works - 4h)
2. Gelling agents for the production of fruit and berry jelly products. Fruit berry marmalade. 2. laboratory work – Preparation of fruit and vegetable marmalades. (Lecture - 1h; laboratory works - 3h).
3. Fruit and berry juices. 3. laboratory work – Types of juice extraction, quality evaluation. (Lecture - 1h; laboratory works – 2h)
4. Fruit, berry, vegetable freezing: technologies, changes during freezing. 4. laboratory work – Analysis of frozen fruits and vegetables. (Lectures – 2h; laboratory works – 3h)
5. Oils, their classification, extraction technologies 5. laboratory work – Oil analysis. (Lecture – 1h; laboratory works – 4h).
6. Test. Lecture-seminar: Fruit and vegetable processing companies. (Lecture – 2h).
Laboratory works have been visited, developed and defended.
Successfully written theoretical test.
During the semester students have to develop one independent work on the topic “Fruit and Vegetable Processing Companies in Latvia”. A PowerPoint presentation on this topic should be prepared and presented during the planned seminar. Presentation is evaluated with a test.
The study course ends with an exam. During the semester, all the laboratory and practical works must be worked and defended, and a complete test of the lecture material must be written successfully.
If at least 6 (almost good) grades have been obtained in all tests during both semesters, then student can qualify for the accumulative exam, which is assessed as the arithmetic mean of the tests.
