Introduction to Food Science

Why does bread go mouldy in a few days while honey keeps for years? Food science answers questions like this, and it sits behind every safe, consistent food product.

Every decision in a food business rests on science, whether anyone notices it or not. How long a pot of rice is left to cool, the pH of a sauce, the temperature of a cold room and the date printed on a pack are all choices about chemistry and microbes. People who understand why those choices matter make fewer mistakes, and they can explain their decisions to auditors, customers and colleagues.

Introduction to Food Science is a 16-hour online course for school leavers, first-year students, career changers, new staff in food businesses and anyone who wants to know what really happens to food. It assumes school-level science and nothing more. Every technical term is explained the first time it appears, and the examples come from ordinary kitchens, shops and factories.

What the course covers

Seven modules: what food science is and how foods are classified; the chemistry of water, carbohydrates, proteins, fats, vitamins and pH; browning, rancidity, enzymes, emulsions and gels; food microbiology and what microbes need to grow; nutrition and health; taste, smell, texture, food quality and additives; and how food is preserved and kept safe, from the WHO Five Keys to HACCP, Codex and reading a food label.

Each module opens with its learning outcomes and closes with a case study or kitchen experiment, a knowledge check and a game. You will sort a supermarket shelf by how quickly each food spoils, decide what to do with a pot of rice at a party buffet, and track a cheese sandwich from cow and wheat field to lunch box. Every lesson has a Listen to this lesson option. All activities, knowledge checks and games are compulsory and open in order.

The course ends with a capstone project and a proctored final assessment: 40 questions drawn at random, so every attempt is different. 60 minutes, 70 percent to pass, 3 attempts.

Your certificate

Pass the final assessment and you receive an ASC Food Safety Certificate of Achievement for Introduction to Food Science. It shows your name, the course, the completion date and a unique verification ID with a QR code, so an employer or auditor can check it online at ascfoodsafetytraining.com. You can download it from your dashboard as soon as you pass.

The course was developed by ASC Food Safety’s multidisciplinary team of industry professionals, led by Mthokozisi Nkosi, with contributions from specialists in brewing, dairy processing, meat processing and nutrition. It follows international references: Codex Alimentarius, ISO 22000 and WHO and FAO guidance.
