Certainly, the specific food operator increases additive consumption, out-of-range and uses food additive wantonly, will bring the potential safety hazard to food.
In fact, our country employs history of food additive to be far for a long time. As far back as the Eastern Han Dynasty, ordinary people, on using the salt brine to make, solidify pharmaceuticals and make bean curd; Since the Southern Song Dynasty, people have processed the deep-fried twisted dough sticks according to the deep-fried twisted dough sticks prescription of vitriol two alkali three salt, the deep-fried twisted dough sticks and bean curd have still been the good and inexpensive food on dining tables of ordinary people up to now.

The arrival of industrial era, has changed the food with rural tradition to produce mode and food consumption mode greatly, make the food become the goods, and carry on food trade beginning the large range. This means food from eating the material between the dining tables " The journey " Lengthen, need to pass the large-scale production, preserve, transport, sell 4 basic links, so, food additive is used extensively and in a large amount.
The modern food industry is due to additive

For example use sour inner ester of glucose to make bean curd and solidify pharmaceuticals, the ones that help the bean curd to produce are mechanized and automizing. The automation of food production can prevent the polluting artificially of food.
For example, the diabetic is unsuitable to eat the food high in candy content that additive can meet some people's special requirement, while processing for them and manufacturing the food, can add non- nutrition edulcorant or low heat energy edulcorant, such as wooden the intersection of candy and alcohol, the intersection of A and Sri Lankan sweet, etc bar have.
