Food Chemistry Fundamentals

3-4 weeks

Study the chemical composition of food: water and water activity, carbohydrate chemistry (starch gelatinization, sugar reactions), protein structure and denaturation, and lipid oxidation.

Food Microbiology

2-3 weeks

Learn about microorganisms in food: beneficial microbes (fermentation cultures), spoilage organisms, food-borne pathogens (Salmonella, Listeria, E. coli O157:H7), and factors controlling microbial growth.

Food Processing and Preservation

3-4 weeks

Study thermal processing (pasteurization, sterilization), non-thermal methods (HPP, irradiation), dehydration, fermentation, freezing, and hurdle technology. Understand D-values and Z-values.

Food Safety and Quality Assurance

2-3 weeks

Master HACCP principles, Good Manufacturing Practices (GMP), food safety regulations (FDA, USDA, Codex Alimentarius), and quality management systems including sensory evaluation methods.

Food Engineering Principles

3-4 weeks

Explore heat transfer, mass transfer, fluid dynamics, and unit operations (mixing, separation, extrusion) as applied to food processing. Study food packaging materials and modified atmosphere packaging.

Nutrition and Functional Foods

2-3 weeks

Study macronutrients and micronutrients, bioavailability, nutrient degradation during processing, food labeling requirements, and the science behind functional foods and nutraceuticals.

Emerging Topics and Innovation

2-4 weeks

Investigate cutting-edge areas: precision fermentation, cellular agriculture, sustainable food systems, nanotechnology in food, clean-label formulation, and computational food science.
