Why add some vinegar to stir fried eggs

Adding vinegar when frying eggs can enhance the taste and help remove fishy odors, while also making the eggs more tender and smooth. The acidity of vinegar can neutralize the fishy smell of eggs and promote protein coagulation, making the texture of scrambled eggs more delicate. The main function of adding vinegar to stir fried eggs is to improve flavor and texture. The acetic acid in vinegar can react with alkaline substances in eggs, reducing the gamey smell, especially suitable for people who are sensitive to gamey smell. During high-temperature cooking, acetic acid can accelerate protein denaturation, causing eggs to solidify faster and avoiding aging caused by excessive heating. Rice vinegar or fragrant vinegar is often used in Chinese cooking. These types of vinegar have moderate acidity and aroma, and will not mask the original flavor of eggs. It should be noted that the amount of vinegar used should not be too much, usually half a teaspoon is sufficient, as excessive use may cause a sour and astringent sensation. In rare cases, adding vinegar may affect the color of eggs. The acidic environment of vinegar can lighten the color of egg yolks. If you pursue a golden appearance, you can reduce the amount of vinegar or replace it with lemon juice. Some people have gastrointestinal sensitivity and consuming acidic foods may cause discomfort. This group of people should avoid this practice. The selection of vinegar should also be cautious. Industrial blended vinegar containing additives may damage the nutrition of eggs. It is recommended to use brewed vinegar.

In daily cooking, the amount and type of vinegar can be adjusted according to personal taste, and it is recommended to prioritize natural fermented vinegar. When frying eggs, you can mix vinegar and egg mixture evenly before putting them into the pot to avoid local sourness. Paired with seasonings such as scallions and pepper, it can further enrich the flavor. Eggs are rich in high-quality protein and lecithin, and moderate consumption can help supplement nutrients, but those with high cholesterol levels need to control their intake. Pay attention to the heat when cooking to avoid nutrient loss caused by prolonged heating at high temperatures.
