Why are Pepsi Extreme and Coca-Cola Zero both claiming sugar-free, but so sweet?

Pepsi's jealousy and Coca-Cola's zero degree all claim to be sugar-free, but they are all called sucrose-free. Look carefully, they may add sweeteners, such as xylitol, orange powder and so on. Although it is not sucrose and its calories are relatively low, it is sweet. You are like a very, very lovely thing. So our narrow sense of sugar refers to the broad sense of sucrose, and that's all. Look at monosaccharides and disaccharides. You are like our glucose, and he belongs to monosaccharide sucrose, that is, dragon sugar. You are like my soft candy, and then this sugar, the kind of sugar he called the second sugar. You want xylitol, just wait. It is the sweetener of these things, so we have a moderate sense of sweetness. It is an ingredient, so feelings and ingredients cannot be completely equal. Our sense of taste deceives us.
