• Lipid metabolism: Beta-oxidation, ketogenesis, lipogenesis, and the roles of different fatty acids in health and disease. The impact of dietary fats on cardiovascular health is a major focus.
• Protein metabolism: Protein synthesis, degradation, and the roles of essential amino acids. This includes exploring the impact of protein deficiency and excess on health.
• Vitamin and mineral metabolism: The roles of individual vitamins and minerals in various metabolic processes, their bioavailability, and the consequences of deficiencies or toxicities. This often involves exploring the interactions between different nutrients.

2. Food Microbiology and Food Safety:

This crucial aspect focuses on the microorganisms that can contaminate food and the methods to prevent foodborne illnesses. Topics covered include:

• Bacterial growth and control: Understanding the factors affecting bacterial growth (temperature, pH, water activity) and methods for controlling bacterial contamination (heating, cooling, irradiation, preservatives). This involves in-depth knowledge of pathogenic bacteria like Salmonella, E. coli, and Listeria.
• Viral and parasitic contamination: Learning about foodborne viruses (e.g., norovirus, hepatitis A) and parasites (e.g., Toxoplasma gondii) and their transmission through food.
• Food preservation techniques: Exploring various methods of preserving food, including canning, freezing, drying, fermentation, and high-pressure processing, and their impact on microbial safety and nutritional value.
• Hazard Analysis and Critical Control Points (HACCP): A systematic approach to identifying and controlling food safety hazards throughout the food production process. This is a crucial aspect of ensuring food safety in industrial settings.

3. Food Chemistry and Processing:

This module explores the chemical changes that occur during food processing and their impact on food quality and nutritional value. Topics include:

• Enzymatic reactions in food: Understanding the role of enzymes in food spoilage and processing, and methods for controlling enzymatic activity.
• Non-enzymatic browning reactions: The Maillard reaction and caramelization, their impact on food flavor and color, and their implications for food processing.
• Food texture and rheology: The study of the physical properties of food, including texture, viscosity, and elasticity, and how these properties are affected by processing.
• Food processing technologies: Exploring various food processing techniques, including extrusion, homogenization, and high-pressure processing, and their impact on food quality and safety.

4. Human Nutrition and Dietary Needs:

This module expands upon foundational nutrition, focusing on:

• Dietary assessment methods: Learning different methods for assessing dietary intake, including food frequency questionnaires, 24-hour dietary recalls, and food diaries.
• Nutritional requirements for different life stages: Understanding the specific nutritional needs of infants, children, adolescents, adults, and older adults. This also includes exploring the nutritional needs of pregnant and lactating women.
• Nutritional requirements for specific populations: Understanding the nutritional needs of individuals with specific health conditions, such as diabetes, cardiovascular disease, and cancer.
• Dietary guidelines and recommendations: Learning about national and international dietary guidelines and recommendations, and their application in promoting health and preventing chronic diseases.

5. Food Product Development and Sensory Evaluation:

This module introduces the principles of food product development and sensory evaluation. Students will learn about:

• New product development process: Understanding the stages involved in developing new food products, from concept generation to market launch.
• Sensory evaluation methods: Learning different methods for evaluating the sensory properties of food, including descriptive analysis, affective testing, and consumer acceptance testing.
• Food packaging and shelf-life: Understanding the role of packaging in preserving food quality and extending shelf life.
• Food labeling and regulations: Understanding the regulations governing food labeling and the information that must be included on food labels.

Practical Applications and Skills Developed:

Level 3 Food Science and Nutrition provides extensive practical experience through laboratory work, projects, and potentially internships. Students will develop crucial skills in:

• Laboratory techniques: Conducting various laboratory experiments related to food analysis, microbiology, and chemistry.
