First, preservatives affect health. People pay great attention to the ingredients of food in daily consumption, and the scale of preservatives is also very strict. This is because we all know that preservatives will have some adverse effects on the human body. Of course, when baking pancakes, don't add preservatives, because pancakes are food that people eat every day. It is best to eat it after it is cooked, and it should be eaten fresh, which is better for the human stomach and tastes better. Cake stored for too long tastes dry and chews expensive. In order to keep the cake for a long time, it is even more unnecessary to put preservatives. Why don't you cook less every time you want to eat, eat fresh food, and do it next time you want to eat, so don't bother.
Second. Don't buy cakes with preservatives. Want to eat pie? Many people may go out to buy some cakes besides baking them at home. Then some people will say that the cakes sold outside are all added with preservatives, but this is not the case. Conscious merchants will not add additives other than food in the process of baking cakes, because they sell a lot of food and there is no need to add preservatives to preserve it. Preservatives are initially added to prepared pies, which does not help food improve its taste or appearance. So, if you know which pie outside has preservatives, you can exclude it from the buyer.
In short, when buying food in daily life, or when cooking at home, we should prevent adding preservatives, because it is a negative food. It is not good for people's health, so avoid adding preservatives when baking cakes or going out to buy cakes.
