Check If Your Eggs Are Fresh Using Just Your Smartphone: Three Easy Methods

Ever brought eggs home from the market only to discover they were spoiled when you cracked them open? With your smartphone, you can now check the freshness of eggs without breaking them. Here are three simple ways to do it.

1. Flashlight Test – The Most Common Method
The easiest way to check if an egg is fresh is by using your phone’s flashlight. For this, you’ll need a dimly lit room. Place your phone on a table with the screen facing down and the flashlight pointing upward. Then hold the egg over the light.

• Fresh Egg: You will see a soft yellow or orange glow inside.
• Spoiled Egg: Dark spots, cloudiness, or complete darkness inside indicate that the egg is bad.

2. Using Smartphone Apps
Several apps, like Egg Freshness Tester or Candling Eggs, available on the Play Store, help you estimate egg freshness. Some apps require information such as purchase date, while advanced apps use your phone’s camera and sensors to analyze the egg’s interior.

While these apps are not 100% accurate, they provide a good estimate and are particularly useful for those who consume eggs regularly for protein or fitness purposes.

3. Video Recording Method
Another effective way is to record the egg using your smartphone camera under bright light. Slowly rotate the egg while recording and later review the footage in slow motion.

• Fresh Egg: The liquid inside moves smoothly without dark spots.
• Spoiled Egg: Large air bubbles or dark patches inside indicate that the egg is old or bad.

Tips for Best Results
The flashlight and video recording methods generally give the most reliable results. Apps, on the other hand, can sometimes be inaccurate as they rely on user-provided information to estimate freshness.

Using these simple smartphone techniques, you can ensure that the eggs you consume are fresh, saving yourself from unpleasant surprises and potential health risks.
