Yes, peanut oil can freeze, but it requires temperatures significantly lower than a standard home freezer.
Peanut oil, being a vegetable oil composed of various fats, doesn't have a single, distinct freezing point. Instead, it solidifies over a range of temperatures. The temperature at which pure peanut oil begins to freeze is around 14 degrees Fahrenheit (-10 degrees Celsius). However, the exact freezing point can vary slightly depending on the specific composition and any impurities present in the oil. Most home freezers are set to around 0°F (-18°C), which may not be cold enough to fully freeze peanut oil, but could cause it to become cloudy or partially solidify.
Therefore, while technically possible, freezing peanut oil is unlikely to occur in a typical home freezer.
