2. As an essential ingredient or ingredient of some special foods, such as potassium carbonate in infant formula foods.

In fact, for most processed foods, it is almost impossible to produce them without adding appropriate food additives. So, will food additives cause harm to human body? According to Shenyang Daily, the state has strict regulations on the dosage, scope and methods of various food additives. These regulations are based on a scientific and rigorous toxicity assessment, so as long as the food produced by regular manufacturers contains food additives, it will not endanger human health.
In addition, many people are very concerned about the shelf life of food when buying food, and think that food with long shelf life is not good for health. However, according to the Health Times, the shelf life marked on food packaging is determined by enterprises according to many specific experiments, so the shelf life of different kinds of foods will vary greatly, such as bread and vegetables, while the shelf life of biscuits and drinking water is relatively long. Moreover, due to the differences in processing methods, even the same food may have different shelf life. For example, some milk has a shelf life of half a year, and some milk has a shelf life of only a few days. However, as long as it is produced by regular manufacturers and tested by relevant testing institutions, it will not endanger human health. So when you buy food, you'd better go to some large supermarkets to ensure that you buy fresh and regular food. ?
