When the temperature is 2-5℃, the shelf life of eggs is 40 days, while it is 15 days in winter and 10 days in summer. If the shelf life is exceeded, the freshness and nutritional components of eggs will be affected to some extent. Storage time is too long, eggs will deteriorate due to bacterial invasion, and there will be phenomena such as shell sticking and yellowing. Fortunately, many supermarkets have begun to sell fresh eggs marked with the date of production, which is convenient for calculating the shelf life according to the date. If you buy eggs in bulk, try to buy less at a time and eat them as soon as possible.

According to the freshness, season, temperature and freshness of the eggs you bought, the shelf life will be long if they are kept reasonably, otherwise they will be short. When buying eggs, you should choose the eggshell with powdery luster. This kind of egg is usually fresh and can be kept for a relatively long time. Try not to pick eggs stained with chicken manure. If you accidentally buy it, eat it first.
