Contents of other main nutrients (protein, amino acids, iron, calcium, phosphorus, etc.). ) is basically the same as that in natural eggs, except that the fat content of natural eggs is about 1% higher than that of ordinary eggs, and the cholesterol content is slightly higher. It is worth noting that the contents of vitamins and minerals in eggs produced on a large scale in chicken farms are slightly higher than those in native eggs, which is related to the richer nutrients provided in the feed.
It is precisely because the fatty acid and lecithin content of earth eggs is slightly higher than that of ordinary eggs that they taste more fragrant? . In addition, some fat-soluble flavor components will be transferred to the eggs when the native chickens eat insects, grass and chicken food during the feeding process, which may be one reason why the native eggs taste more fragrant.
How to choose good eggs:
1, Pick clean eggs: Many people think that eggs with chicken feathers or chicken droppings are relatively fresh eggs, or eggs laid by free-range chickens, which is wrong. Unclean eggs may have health hazards themselves, so look clean after eating them.
2. Choose a formal place: please choose a formal supermarket or a large farmer's market to buy eggs.
3. Look at the eggshell: There is a layer of frosty substance on the eggshell of fresh eggs. The surface looks dull and feels rough.
4. Weight: Relatively speaking, the heavier and fresher an egg of the same size is, the less water substance volatilizes.
5, listen to the sound: when buying eggs, you can pick up the eggs and gently shake them in your ear. Fresh eggs have no sound, because the space inside is full. If it is not fresh, the air chamber inside will become bigger and there will be a feeling of shaking water.
