Dairy Product Refrigeration Tips for Quality
Dairy product refrigeration is essential in the dairy industry to maintain product safety, flavor, and longevity. Whether you process milk, yogurt, or cheese, proper temperature control protects food integrity and consumer health. Below, we explore the best practices for preserving dairy items safely.
Preserving Dairy Products: Why Temperature Matters
Milk from healthy cows contains natural inhibitors like lactoferrin and lactoperoxidase. However, bacterial activity increases quickly without fast cooling. Bringing milk to 4°C shortly after milking helps preserve its original composition.
Optimal Cooling Temperature
Milk should be stored between 3°C and 4°C. Lower temperatures may cause freezing, affecting the structure of fats and proteins. Warmer temperatures promote unwanted microbial growth and spoilage.
Storage Duration and Sanitation
As time passes, bacteria can multiply even in cold conditions. Clean milking tools and tanks reduce contamination risk. Use a controlled refrigeration system to limit storage time to industry standards.
Fast Cooling and Equipment
Quickly cooling milk is crucial. Stainless steel tanks with integrated cooling systems are widely used in the dairy sector to ensure efficiency during the first hours post-milking.
Keeping the Cold Chain Unbroken
Once chilled, milk and dairy goods must stay cold throughout storage and transport. According to EU food safety guidelines, raw milk must not exceed 8°C—or 6°C if collected less frequently. Products for processing must remain below 6°C until transformed.
Shelf Life of Refrigerated Dairy
- Raw milk: 72 hours
- Spreadable cheese: 15 days
- Yogurt and cream cheese: 21 days
- Mozzarella and similar cheeses: 30 days
Refrigeration, Pasteurization, and Freezing
Cooling is often paired with pasteurization to reduce bacteria. Freezing is used for items like ice cream, which require storage at -18°C or lower. However, freezing is not ideal for all dairy types due to texture degradation.
