Various baked goods has become an integral part of the daily diet. The protein in flour consists mainly of gliadin and glutenin, the former is globose and has good extension, but lack of flexibility; the latter is fibrous and full of elastic. Do you know what is a food additive? Let's talk about it. In order to make the two protein reach to a more appropriate ratio and cross-linking, antioxidants need to add to adjust. In the past couple of decades, potassium bromate as a cheap and powerful oxidants have been applied in global food baking industry. Potassium bromide dissolve slowly, with the acidity of the dough and the baking temperature rise, the bread is elastic.

Types of food additives are added to the food to ensure the taste. But the food and safety is still an issue that people focus most. The 80 's of the last century, researchers found that potassium bromate in the experimental conditions are all carcinogenic to animals. then many countries began banning the potassium bromate as a flour additive. Meanwhile, safe, effective and cheap azo-carboxamide started to replace potassium bromate and has been widely applied to flour the baking process. Although the study found that products contain azo formamide nitrofurazone metabolite conversion rate is very low, but EU countries do not allowe azo formamide to use as a flour improver. This is to ensure the food safety.

Food additive manufacturing process are many, synthetic, bio-fermentation, natural extracts, etc are included. For example, the production of citric acid is fermented by grain as a raw material. And some food additives are natural extracts, such as pepper, ginger oil and capsicum red pigment. As long as the use of food additives in accordance with standards, the safety is not a problem. However, he ultra range, excessive use could cause food safety problems. For example, tartrazine is a food additive that can be used in ice cream, juice and other food, while it can not be used in the bread.
To further strengthen the sense of safety of food additive, the enterprises should have responsibility of food safety. Choose a reliable suplier is important,. It is a basis for ensuring food safety. A reliable and qualified suplier will strictly in accordance with the food safety standard to test and produce the food additives. As far as possible through formal channels to choose food additives can ensure the safety from your tongue.
