What Makes Eggs Float?
Eggs float due to the increasing size of the air cell inside the egg as it ages. Fresh eggs have a small air cell, which keeps them denser than water, causing them to sink. As the egg gets older, moisture and air seep in, enlarging the air cell, which can cause the egg to float. Here are some key points to consider:
- Fresh eggs sink to the bottom and lie flat on their sides.
- Eggs that stand upright on the bottom are still usable but should be cooked soon.
- Eggs that float to the surface are likely bad and should be discarded.
Egg Freshness and Safety
Understanding egg freshness is critical for food safety. According to the USDA, eggs can be safe to eat for several weeks after their sell-by date if stored correctly. However, the float test is a practical way to assess their quality. Here are some factors that influence egg freshness:
- Storage Temperature: Eggs should be stored in the refrigerator, ideally at a temperature of 40°F (4°C) or below.
- Packaging: Keeping eggs in their original carton helps protect them from absorbing odors and flavors from other foods.
- Sell-by Dates: Always check the sell-by date, but remember that eggs can still be good past this date if they have been stored properly.
Testing Your Eggs: The Float Test
The float test is a simple and effective method to check the freshness of your eggs. Here’s how to do it:
- Fill a bowl or glass with water.
- Gently place the egg in the water.
- Observe the egg's behavior:
- If it sinks and lies flat, it is fresh.
- If it stands upright on the bottom, it is still good but should be used soon.
- If it floats to the surface, it is likely bad and should be discarded.
How to Store Eggs Properly
Proper storage of eggs can significantly extend their freshness and safety. Here are some tips:
- Store eggs in the coldest part of the refrigerator, not in the door.
- Keep eggs in their original carton to maintain moisture and prevent odors.
- Avoid washing eggs before storing them, as it can remove their protective coating.
Signs of Bad Eggs
In addition to the float test, there are other signs to look out for when determining if an egg has gone bad:
- Smell: A rotten egg will emit a sulfur-like odor when cracked open.
- Appearance: Check for any unusual discoloration or a cloudy egg white.
- Texture: If the egg white is unusually runny or the yolk is flattened, it may be past its prime.
