European Dairy: A Look at Pasteurization
The idea that European dairy is not pasteurized is a common misconception. The vast majority of dairy products sold commercially in the European Union (EU) have undergone a heat treatment to ensure safety. Specific methods, market dominance, and regulations on raw milk differ from North America and vary among European nations.
The Importance of Pasteurization
Pasteurization is key to the EU's food safety laws. This process is crucial for public health, as raw milk can contain dangerous bacteria. Pasteurization does not diminish the nutritional value of milk. Instead, it provides a safe, nutrient-rich product.
UHT vs. HTST: Two Methods
Differences in perception about European dairy are due to the heat treatment methods used. While North America uses High-Temperature Short-Time (HTST) pasteurization for refrigerated milk, Europe uses Ultra-High Temperature (UHT) treatment for long-life products.
- UHT (Ultra-High Temperature) Pasteurization: This method heats milk to 135-140°C (275-284°F) for a few seconds. This kills virtually all bacteria, making the milk shelf-stable for months in sealed packaging. UHT milk has a slightly different flavor.
- HTST (High-Temperature Short-Time) Pasteurization: This heats milk to about 72°C (161°F) for 15-20 seconds. It kills harmful bacteria but does not eliminate all spoilage microbes, which is why the milk still needs to be refrigerated and has a shorter shelf life.
Comparison Table: UHT vs. HTST
| Feature | UHT Pasteurization | HTST Pasteurization |
|---|---|---|
| Temperature | 135-140°C (275-284°F) | ~72°C (161°F) |
| Time | 2-5 seconds | 15-20 seconds |
| Refrigeration | Not required for sealed products | Required |
| Shelf Life | Months (unopened) | 1-2 weeks (unopened) |
| Taste | Slightly 'cooked' flavor | Fresher, creamier taste |
| Nutritional Impact | Minimal impact on major nutrients, some loss of heat-sensitive vitamins | Very minor, retains most vitamins |
| Packaging | Aseptic cartons | Refrigerated plastic jugs or cartons |
Raw Milk in Europe
While most commercial dairy is pasteurized, Europe's approach to raw milk sales varies.
- Germany: The sale of raw milk is generally prohibited, with an exception for direct 'farm-gate' sales.
- Italy: Italy allows the sale of raw milk directly from producers. Cheeses made from raw milk are also common, though labeling is required for cheeses aged less than 60 days.
- France: In France, both pasteurized and UHT milk are sold. Raw milk (lait cru) is available, especially for artisanal products like certain cheeses.
- United Kingdom: In England, Wales, and Northern Ireland, raw drinking milk is available but only through direct sales channels. A health warning label is mandatory.
Labeling of Dairy Products
The key is to read the labels. Look for:
- Pasteurisé / Pasteurised: Indicates standard pasteurization (HTST).
- UHT / Ultra-pasteurisé: Indicates Ultra-High Temperature treatment.
- Lait cru / Raw milk: Identifies unpasteurized milk or cheese.
Conclusion
Europe does pasteurize its dairy. The key difference is the widespread use of UHT pasteurization, which allows for shelf-stable products. However, the continent's diverse culinary landscape also supports regional exceptions and traditions, with varied regulations on raw milk products across different nations. Consumers should read labels to get the product they expect.
