🧑🔬 Dairy technologist
Also known as: food technologist
A specialist who selects recipes and milk-processing settings at a dairy plant, including pasteurization at 72 °C.
A dairy technologist is the specialist responsible for how raw milk becomes a finished product: choosing the recipe, the temperature and the processing time, and making sure the plant sticks to them. The work happens at a dairy, in a lab or in a development department, and covers research on quality, safety and new products.
The route into the job differs from country to country. In the United States, according to the Bureau of Labor Statistics (BLS), food technologists usually need a bachelor's degree in food science or a related field. In Germany it is a profession not regulated by the state: specialists process raw milk, monitor quality, and package and store products. Britain has a separate training standard for the dairy technologist, developed together with dairy companies.
The main tool is the heating regime. Under the US definition, pasteurization means heating every particle of milk to a set temperature and holding it there: about 63 °C for 30 minutes or 72 °C for 15 seconds. Ultra-pasteurization is at least 280 °F (about 138 °C) for 2 seconds.
Safety is part of the job. Regulation (EC) 852/2004 requires producers to keep a permanent procedure based on HACCP principles and to train the people who design and maintain it. On the production floor, according to BLS, workers meet machine noise, heat or cold, so protective clothing, gloves or a mask are needed.
Why it matters to you. The words “pasteurized” and “ultra-pasteurized” mean different heating regimes. In the US, ultra-pasteurized milk by definition keeps longer in the cold. Read the label and store the product as the producer says.

Frequently asked questions
What does a dairy technologist do at a dairy?
Chooses recipes, temperatures and processing times for milk, checks that they are followed on the line, and develops new products.
At what temperature is milk pasteurized?
Under the US definition, about 63 °C for 30 minutes or 72 °C for 15 seconds; the table also lists higher temperatures with shorter holding times.
What education does a dairy technologist need?
In the US, according to BLS, usually a bachelor's degree in food science or a related field. In Germany the profession is not regulated by the state, and Britain has a training standard for the dairy technologist.
Is it true that pasteurization and ultra-pasteurization are the same thing?
No. Pasteurization is about 63 °C for 30 minutes or 72 °C for 15 seconds. Ultra-pasteurization is at least 280 °F (about 138 °C) for 2 seconds, and the milk keeps longer in the cold.
Is a dairy technologist legally responsible for milk safety?
Regulation (EC) 852/2004 places responsibility on the food business operator, who sets up a HACCP-based procedure and makes sure its designers are trained. The regulation does not name the job of dairy technologist.
What to read next
- 🏭 Dairy plant — A plant that receives raw milk and turns it into drinking milk, cream, fermented milk products, cheese, butter and milk powder.
- ✅ Quality control — Fat, protein, bacteria, antibiotics, acidity.
- 🍷 Oenologist — An oenologist (enologist, œnologue) is a trained wine scientist who oversees analysis, fermentation, ageing and quality from grape to bottle.
- 🥛 UHT milk — Milk heated to 135–150 °C for 2–10 seconds and filled aseptically; unopened, it keeps for months without a refrigerator.
- 🧑 Human — Also a mammal; the only species that milks other animals itself and drinks their milk throughout life.
