Tips to distinguish bleached chicken eggs and principles of egg preservation
When buying chicken eggs, distinguishing between fresh eggs and bleached eggs is very important to ensure quality and food safety. Besides, properly storing eggs also plays an important role in keeping eggs fresh and undamaged.
When looking to buy eggs, choose fresh eggs. Fresh eggs have firm whites, plump yolks and no strange odors. To distinguish between fresh eggs and bleached eggs, you can rely on some of the following characteristics.
Bleached chicken eggs are usually larger in size than fresh eggs. The weight of bleached eggs usually ranges from 55 – 60g, while fresh eggs are smaller with a weight of only about 45g. Additionally, bleached eggs have shells that look rough, wrinkled, and have a pinkish white color. The egg surface has a layer of white dust and is not shiny or clean like fresh eggs. Meanwhile, fresh eggs have a naturally white shell and may have some stains on the surface.
After purchasing eggs, storing them properly is very important to prevent spoilage and ensure food safety. First, you should not wash eggs with water when you first buy them. Instead, use a soft, wet cloth to clean the egg surface. Washing eggs with water can remove the natural protective layer on the egg shell and allow bacteria to penetrate inside.
Eggs after cleaning need to be stored properly. Do not leave eggs in the refrigerator door because uneven temperature changes cause eggs to spoil quickly. Instead, wrap eggs in newspaper or put them in a cardboard box before putting them in the refrigerator. Wrapping eggs or putting them in a carton box helps protect them from impact and direct contact with air in the refrigerator.
If you don’t have a refrigerator, store eggs in a cool, airy place to avoid spoilage. Eggs need to be stored in an environment with appropriate humidity and temperature to avoid rotting or losing freshness.
Egg storage time in the refrigerator is usually 3 to 5 weeks. However, if you have taken eggs out of the refrigerator, you should use them within 2 hours to ensure food safety.
In addition, when buying eggs, check to see if they are cracked or dirty. Cracked eggs can allow bacteria to enter and quickly spoil the eggs. Be careful to inspect eggs before buying and only choose eggs that have no cracks and are not dirty.
In addition to the above advice, there are also some egg preservation principles to keep in mind. First, do not wash eggs with soap or detergent. If the eggs are dirty, use a soft wet towel to gently wipe the egg surface without using detergent. Washing eggs with water can remove the natural protective layer on the egg shell and allow bacteria to penetrate inside.
Second, eggs should be stored in the refrigerator, not in the refrigerator door. The cooler has a more stable temperature and avoids temperature changes when opening the refrigerator door. Place the eggs in a cardboard box or wrap them in newspaper to protect them from impact and from direct contact with the air in the refrigerator.
Finally, eggs need to be stored in a place with suitable humidity and temperature. Too much humidity can cause eggs to rot, while too little humidity can cause the yolks and whites to dry out. Extremely high temperatures can also cause eggs to spoil quickly. Therefore, make sure eggs are stored in a cool environment and have the right humidity.
In short, to distinguish bleached chicken eggs, carefully observe characteristics such as size, eggshell and color. At the same time, comply with egg preservation principles to ensure quality and food safety.
