AIM
The course aims to develop the knowledge of students in the basic area of Food Chemistry.
This is necessary for effective understanding of food processing and technology subjects.
This course will enable students to appreciate the similarities and complexities of the
chemical components in foods.
OBJECTIVES
On completion of the course the students are expected to
 Be able to understand and identify the various food groups; the nutrient components
(macro and micro), proximate composition.
 Be able to understand and identify the non-nutritive components in food, naturally
present.
 Understand and use effectively, food composition tables and databases.
 Grasp the functional role of food components and their interaction in food products in
terms of colour, flavour, texture and nutrient composition
