| Objectives of the Course | |||||
| The course aims to emphasize the importance of the biochemistry of major food ingredients and to understand in detail the biochemical changes in food during processing and storage. At the end of the course, students will have the knowledge to understand the biochemical properties of the main food ingredients and to examine the biochemical changes that occur during the obtaining, processing and storage of foods and to have an idea about their effects on quality. | |||||
