It is healthier to blanch the toon before making it because it contains a certain amount of nitrates and nitrites, which are harmful to the human body. Blanching can help remove some of the nitrates and nitrites, which do not cause significant discomfort if ingested in small amounts once in a while, but can affect human health if ingested in large amounts. The first thing you need to do is to remove the nitrates and nitrites: too much nitrate can be reduced to form nitrites in the human body, and a lot of nitrites can be oxidized with hemoglobin in the red blood cells of the human body to high iron hemoglobin, which loses its oxygen-carrying capacity and leads to tissue hypoxia, brain tissue Lack of oxygen makes the metabolites increase, easy to produce mental symptoms, which is often referred to as food poisoning. The high temperature blanching can help remove some of the nitrates and nitrites in the toon, so that the possibility of discomfort is lower and can also help reduce the risk of food poisoning; 2, sterilization and insecticide: toon in the growth process, inevitably contaminated with some dust, bugs or bacteria, after eating into the body, easy to induce vomiting, abdominal pain, diarrhea and other discomfort. Blanching at high temperature can effectively kill most bacteria, insect eggs and other harmful substances, so that these substances do not enter the body and reduce the possibility of inducing gastrointestinal discomfort; 3. Improve the taste: blanching the toon can better lock the flavor and color of the toon, maintaining a crisp, sweet taste, without bitterness, and then when cooking with other foods such as meat and eggs, the original flavor of the toon will be retained to a greater extent, more It has edible value. Therefore, from the perspective of food safety and hygiene and to ensure the taste of cooking, it is recommended to blanch the toon before making it, so that you can both eat safely and taste the fresh and delicious toon.
