Cook for 6 minutes: At this time, the egg white can be solidified, but the yolk is not completely solidified, and there is a flowing center. At this time, the anti-nutritional substances (biotin-binding protein, egg inhibitor) of eggs are destroyed, and the nutrients can be retained to the greatest extent, but Salmonella may not be completely killed. ?
Cook for 8 minutes: the egg white has solidified, the yolk has slightly solidified and the color is golden. At this time, the anti-nutritional substances are destroyed, salmonella can also be controlled within a safe range, and the nutritional retention is relatively complete.
Boiling 10 minute: protein in egg yolk continues to denature, and it will taste a little dry and choking, and its color will change from golden yellow to light yellow. At this time, there may be some oxidation loss of vitamin E and omega-3 fatty acids in eggs. ?
Cooking time12min: If the cooking time is too long, the protein will be seriously denatured, and the egg yolk will become hard and choke, which will not only reduce the taste, but also aggravate the loss of nutrients, and even produce a layer of ferrous sulfide black film harmful to health. ?
Extended data
According to Chongqing Evening News, the nutrients of boiled eggs are more difficult to be absorbed by human body than those of fully cooked eggs. Besides protein, eggs also contain many minerals, cholesterol, lecithin and vitamins.
If you eat boiled eggs, the human body can absorb more than 98% of these nutrients, while if you eat boiled eggs, the absorption rate of nutrients can only reach 8 1%. As for whether the nutrients in the eggs will be lost because of the long cooking time.
Xinhuanet explained that heating has little effect on the nutritional composition of eggs, and protein and minerals will not be absorbed by the human body because they are cooked for a few more minutes; The content of vitamins will be slightly affected, but the loss is not big, so don't worry.
