How to store free-range eggs for a long time? A few practical methods to teach you
Free-range eggs keep for a long time when stored at low temperature, generally about 40 days, while at room temperature the shelf life of free-range eggs is 15 days, and during high summer temperatures the shelf life is 10 days. But if bought from a supermarket, they generally have no production date marked, so it is best to buy only as many as you will eat. In addition, when storing them, try to wrap them in cling film, as this can prevent the Salmonella on the eggs from contaminating other foods.
How do you tell whether an egg is expired?
1. Look at the appearance
A good egg has a fresh, bright color on the shell surface, and it looks as if a thin film covers it; the pores on the shell surface are relatively small, and you can see tiny raised specks plus a white bloom, with no cracks; whereas an expired egg has mold spots, speckles or a dull color.
2. Smell it
A good egg has no smell, whereas an expired, rotten egg releases a lot of sulfides and has a rotten-egg smell.
3. Look at the yolk
A good egg has a thick yolk with a deep color, and it looks very smooth, whereas an expired egg has a runny yolk and a flat color.
4. Soak it in water
A good egg is relatively heavy in density and will sink when put in water, whereas an expired egg contains a lot of gas and will float when put in water.
The above is the relevant introduction on how to store free-range eggs for a long time; I hope it is helpful to everyone.
