Eggs are one of the most commonly eaten foods. The nutritional value of eggs is relatively high. It can be said that they are very nutritious. The price of eggs is very low. They are delicious and inexpensive. When we buy eggs, we must choose fresh eggs. There are certain methods to choose fresh eggs, such as whether the eggshell is smooth, etc. Let us learn about this aspect below. How to choose fresh eggs 1. Small to medium size – Older chickens will produce larger eggs, but old chickens are more susceptible to disease, so try to choose eggs that are small to medium in size. 2. Eggshell is smooth – A rough eggshell indicates that the chicken has lost calcium, and the eggshell will also be thinner and easier to break. The fresher the egg, the smoother and harder the eggshell. 3. Eggs that sink to the bottom of the water are good eggs – Fresh eggs have smaller air cells and contain less air, so they are heavier than old eggs. Put the egg in water. If it sinks to the bottom, it is a fresh egg. 4. The egg white is turbid and coagulated, and the yolk is plump and bulging. Fresh egg whites are elastic and cohesive, and will gradually become thinner and watery over time; fresh egg yolks are plump and raised, while old egg yolks are flat. Hold your egg up to the light. If the yolk is in the center, the white has not lost its vitality and elasticity. It is a good egg! How to choose fresh eggs 1. View How to choose eggs? Tips for choosing fresh eggs: The shells of fresh eggs are relatively rough, and there is a layer of frosty powder on the shells. The shells of old eggs are smooth and shiny. Eggshells that have been exposed to rain or become damp and moldy have gray and black spots, while rotten eggs have black shells and some even have oil stains. When purchasing, you can make a preliminary judgment on the quality of eggs by observing the eggshell. 2. Touch How to choose eggs? Tips for choosing fresh eggs: Turn the egg over in the palm of your hand. A good quality fresh egg will have a rough shell and a moderate weight. If it is a poor quality egg, it will feel light and smooth to the touch, which means the egg is no longer fresh. 3. Sniff How to choose eggs? Tips for choosing fresh eggs: Blow a breath of hot air onto the eggshell with your mouth, then smell it with your nose. Good quality fresh eggs have a slight smell of quicklime. 4. Listen Hold the egg between two fingers and shake it near your ear. A fresh egg will make a solid sound and will not shake when it touches the eggshell. This is a fresh egg. Use your hands to pinch a few eggs and gently touch them against each other. If they are low-quality fresh eggs, they will make a rattling sound (hatching eggs) or a hollow sound (splash eggs) when they hit each other. When you shake the eggs in your hand, they will make a shaking sound. 5. Float How to choose eggs? Tips for choosing fresh eggs: Soak the egg in cold water. If it lies flat in the water, it means the egg is fresh. If it is tilted in the water, then it has been stored for at least 3 to 5 days; if it stands upright in the water, it may have been stored for 10 days; if it floats on the water, the egg is likely to have deteriorated. 6. Photo Hold the eggs up to the light in the sun or under the lamp. If the eggs have good light transmittance and are bright in color under the lamp, they are good eggs. You can also use a searchlight to identify the eggs when you buy them. |
