In the freezer 3. In the pantry. 1. Store milk in the refrigerator. Keep milk in the fridge between 40°F and 45°F 4°C and 7°C. This keeps milk from spoiling faster than if left at room temperature.

However, milk that has been refrigerated for longer periods of time more than two weeks should be discarded.
What is UHT milk?
Ultra High Temperature UHT milk is heated above 115 degrees Fahrenheit for 15 seconds. This kills any harmful bacteria and extends shelf life. What is homogenized milk? Answer: Homogenized milk is milk that has been treated to prevent separation into curds and whey. The result is a smooth texture and creaminess.
Effects of heating on milk quality
Heating milk above 100°F 38°C destroys many of the nutrients found in milk. Milk proteins denature during heating, resulting in a loss of solubility and coagulation properties. Heating milk below 140°F 60°C does not affect the nutritional value of milk.How long can milk be stored? Answer: Milk can be stored for about two weeks if refrigerated properly. It can be frozen for longer periods of time.
Why does milk spoil?
Milk spoils because bacteria multiply rapidly at temperatures between 40°F and 120°F 4°C to 49°C. Bacteria multiply faster at higher temperatures. At lower temperatures, the growth rate slows down and the bacteria die off. This process is called pasteurization. Pasteurizing milk kills harmful bacteria such as E. coli 0157:H7, Salmonella, Listeria monocytogenes, Campylobacter jejuni, Clostridium botulinum, Staphylococcus aureus, Streptococcus pyogenes, and Bacillus cereus. These microorganisms can cause illness when consumed. What happens to milk after pasteurization? Answer: After pasteurization, milk loses approximately half of its vitamin C content. Milk also loses about 25% of its protein and fat content, but retains most of its calcium, phosphorus, potassium, and magnesium.
