We are all aware of the saying “don’t cry over spilt milk,” but what about spoiled milk? Finding your milk has gone bad in the fridge can be frustrating. Understanding what causes milk to spoil can help extend its freshness. Milk doesn’t spoil due to age but because of bacteria multiplying inside. The lactose in milk turns into lactic acid, giving it a sour taste and a lumpy texture.
To slow down the spoiling process, avoid introducing new bacteria by not drinking directly from the bottle. Keeping milk chilled below 4°C is crucial as bacteria multiply faster at higher temperatures. The type of milk and how it’s handled determine its shelf life.
Various milk options are available today, from traditional cow’s milk to non-dairy alternatives like oat milk. Pasteurized milk undergoes a heating process to remove harmful bacteria, extending its shelf life to 10 days unopened and 3-7 days once opened.
Oat milk, a popular plant-based choice, can last 7-14 days unopened and 5-7 days after opening when refrigerated. Ultra-filtered milk, like Arla Cravendale, has an extended shelf life of 7 days once opened and 21 days unopened due to additional filtration.
UHT milk, heated to a high temperature for a short time, lasts the longest among milk types. Proper storage at around 2-3°C in the fridge, away from the door, helps maintain milk freshness. Filtered milk, like Arla Cravendale, undergoes a unique filtration process and is packaged in opaque bottles to prevent spoilage.
Checking the milk’s freshness by smelling, looking, and conducting a hot water test can help determine if it’s still okay to consume, despite the labeled date. Understanding how milk spoils and implementing proper storage practices can help prolong its freshness.
Remember, milk’s shelf life can vary, and it’s essential to assess its condition before consuming it.
