Food additives are used to improve food quality, extend the food shelf for easy food processing and increasing the food nutrient composition of a class of synthetic or natural material.
Types of Food Additives
There are about 10 kinds of food additives.
List of the most comman food additive types:
1. Sweetener – commonly used artificial sweeteners are saccharin, sodium cyclamate, aspartame and so on.
2. Preservatives – are most commonly used sodium benzoate, potassium sorbate, sulfur dioxide, lactic acid and so on.
3. Spices – spices are synthesized, but also natural, flavor a lot.
4. Coloring agents – commonly used in the synthesis of the pigment carmine, amaranth red, lemon yellow, indigo and so on.
5. Thickener and stabilizer – may improve or stabilize the physical properties of the cold food, make food look fine lubrication.
6. Dietary Supplement – can enhance and supplement the food of certain nutrients.
7. Antioxidants – can extend the shelf life of food.
8. Leavening agent – some candy and chocolate to add leavening agent, sugar body produces carbon dioxide may be prompted to play a leavening effect.
9. Sourness agent – some drinks, candy and other agents often used to regulate and improve the sour smell of results.
10 Brightener – benzoyl peroxide is the main component of flour brightener.

What use of food additives should be avoided?
What use of food additives should be avoided?
(1) The role of food additive.
Rational use of additives food to prevent food spoilage, maintain or enhance the food’s nutrition, improvement or rich food color, aroma and taste.
(2) The need for the use of additive food.
In fact, do not use preservatives in greater danger, because the deterioration of the food often cause food poisoning disease. In addition, the preservatives in addition to prevent food spoilage, it can kill microorganisms in toxin production of microbial amphotericin song, this is undoubtedly beneficial to human health.
(3) The amount of food additive safety.
Health without any toxic effects or adverse effects of food additives consumption, with the quality of daily intake per kilogram (mg) to indicate that mg / kg.
(4) Does not use toxic additives.
“Formaldehyde” is formaldehyde (Asia), sodium bisulfate, also called the hanging white powder Formaldehyde, a chemical formula NaHSO2 ˙ CH2O ˙ 2H2O. By the reaction of zinc powder and sulfur dioxide and other low-sulfite, and then, after the role with formaldehyde, in a vacuum evaporator, condensed into pieces and prepared. “Formaldehyde” white block or crystalline powder, soluble in water. When room temperature is stable at high temperature decomposition of sulfurous acid, a strong reduction, which has a bleaching effect. Started at 80 ℃ above decomposition of harmful substances, the chemical reaction equation is:
6NaHSO2 ˙ CH2O ˙ 2H2O + 3H2O = 4NaHSO3 + 2HCOONa + HCOOH + 2H2O + 3CH3OH
110 ℃, broken down into formaldehyde, the reaction equation is:
NaHSO2 ˙ CH2O = NaHSO2 + CH2O
NaHSO2 + H2O = NaHSO3 + 2 “H”
It allows people fever headache, fatigue, loss of appetite, etc.. One-time dose of 10g will eat life-threatening. “Formaldehyde” is mainly used in printing and dyeing industry as a rope agent and reducing agent, and its bleaching, corrosion is more effective.
