Additives are added to food in order to improve the quality of the food or to increase the color, aroma and taste of the food or for production and processing needs. It is normal for food to contain additives. What is harmful to human body is the amount of additives. It cannot be said that the use of food additives is necessarily harmful to the human body. Even if it is not an additive, drinking too much water is not good for you. There is a limit to everything, and additives are no exception. Excessive, the human organism is certainly not good. A small amount, can not make the appearance of food or human senses to get the full enjoyment. Do not need to "talk about the agent color change". Too much is not enough. Appropriate use or according to the product instructions in the right amount are harmless to the human body. Don't worry about it.
