Educational Goals

• Convolution of knowledge from the previous modules on Physical Chemistry, Organic Chemistry, Inorganic Chemistry and Biochemistry aimed is describing foods and the changes they undergo during storage/processing from a chemical viewpoint.
• Ability to describe foods at the molecular level.
• Application of chemistry knowledge for understanding the structure and function of foods.
• Composition of new text focused on specific food chemistry topics.
• Analysis and understanding of the role of ingredients in foods.
• Understanding of the role and effect of the ingredients in the macroscopic/functional/technological dimension of a foods material.
• To obtain knowledge on the principles of the preservation and processing of fruits and vegetables.
• To interpret the effect of the factors which affect the various methods of fruit and vegetable processing.
• To describe and assess the stages of processing for the various methods of fruit-vegetable processing and their effect on final product quality.
• To apply the above on fruit-vegetable processing at a pilot scale.

General Skills
