Food preservatives are chemicals added to extend the shelf life of food, but excessive or improper use may cause harm to human health. Therefore, it is very important to choose the safest food preservative.
At present, common food preservatives include sulfate, benzoic acid and its sodium, potassium, calcium salt, sorbic acid and its sodium, potassium, calcium salt, acetylurea, propylene glycol, sodium propionate, sorbitol, etc. Among them, benzoic acid and its sodium, potassium, calcium salts, sorbic acid and its sodium, potassium, calcium salts are commonly used as food preservatives.
Benzoic acid and its sodium, potassium and calcium salts are one of the commonly used food preservatives. Benzoic acid is a natural substance in fruits and vegetables, but the use of benzoic acid and its sodium, potassium and calcium salts should be controlled within a certain range, and excessive use may cause harm to human health. Therefore, the use of benzoic acid and its sodium, potassium and calcium salts should follow the relevant national food safety standards.
Sorbic acid and its sodium, potassium and calcium salts are naturally found in pears, apples, grapes and other fruits, and are widely used in food preservatives. Sorbic acid and its sodium, potassium and calcium salts not only have antiseptic effects, but also can enhance the taste and color of food. Compared with benzoic acid and its sodium, potassium and calcium salts, sorbic acid and its sodium, potassium and calcium salts are safer and will not cause harm to human body.
Therefore, from the perspective of safety, sorbic acid and its sodium, potassium and calcium salts are one of the safest food preservatives at present. However, the use of any food preservative should follow the relevant national food safety standards to ensure the health of the people.
