The vegetable market can make people learn a lot of knowledge. As far as buying eggs is concerned, it contains a lot of knowledge. When you go to the vegetable market (supermarket) to buy eggs, different eggs have different prices, including four pieces of 51 Jin, six pieces of a Jin, and 12 pieces of a Jin. There are also white-shelled eggs, free-range eggs, orchard eggs, native eggs and pollution-free eggs. So what is the difference between these eggs? My mother has been selling eggs for several years. I specifically asked my mother about this question. She knows more about eggs. Generally speaking, the retail price of eggs depends on two aspects: one is the cost of breeding, and the other is the taste of eggs. First, the cost of farming is different.

Most of the four 51-pound eggs are white-shelled eggs or red-shelled eggs. The size of a single egg is relatively large, the shell is thin, the protein and yolk are light yellow, and there are many proteins.

It has a high commercial use. Most restaurants, cake baking shops and breakfast shops use eggs at this price. For businesses, eggs at this price are the mainstream eggs in the commercial catering market, and their annual sales are relatively large.

In addition, the retail price reflects the breeding cost. Only when the breeding cost is low, the retail price will be low. For example, white (red) shell eggs are generally kept in captivity. Hens have a small range of activities, sufficient nutrition supply, high egg production and relatively large eggs, which are common in large laying hens.

Then why do some eggs sell for 6 yuan and 12 yuan a catty? This problem is still related to the breeding cost of laying hens, which is directly related to chicken seedlings, breeding environment, chicken food and human management.

Take orchard chickens and free-range chickens for example, the breeding cost of these two kinds of laying hens will be higher than that of the artificially raised feed laying hens mentioned above, mainly because orchard chickens and free-range chickens have large activity space, large labor input and different food for chickens.

Therefore, there is a difference between artificial captive laying hens and free-range orchard chickens, and the price of eggs is also high and low.

As we said earlier, the yolk of four pieces of 51 kg eggs is light yellow, which is related to the food eaten by chickens. Most of the chicken food put in artificial large-scale laying hens farms is prepared feed. While free-range chickens and orchard chickens are mostly fed with corn grains, and omnivores such as insects and grass can be eaten at the same time, so the color of egg yolk is relatively dark. Similarly, because the cost of feeding food is higher, the retail price of eggs will be expensive, forming a direct ratio relationship.

Second, eggs taste different.

The difference between four pieces of eggs with a weight of 51 Jin and twelve pieces of eggs with a weight of 11 Jin lies in the taste. There is a big difference in the taste of eggs at these two price points. The smell of eggs with a weight of 4.5 Jin is relatively light, while that of eggs with a weight of 12 Jin is relatively fragrant and has a good taste. Put 4.5-piece eggs and 12-piece eggs in a pot and peel them. You will find that 12-piece eggs are relatively tight, while 4.5-piece eggs are relatively loose and have a light flavor.

Conclusion: In fact, four 5-Jin eggs and 12-Jin eggs have different breeding costs, different tastes and different nutritional values. If you want to eat delicious food, it is recommended to buy eggs that are slightly more expensive.
