1¡¢ Chemical properties of sodium benzoate and potassium sorbate
The chemical name of sodium benzoate is sodium benzoate, with a chemical formula of C7H5NaO2 and a molecular weight of 144.11. It is a white powder with high solubility in water, which can effectively prevent the growth and reproduction of various microorganisms, and is therefore widely used as a preservative in food.
The chemical name of potassium sorbate is potassium sorbate, with a chemical formula of C6H7KO2 and a molecular weight of 160.21. It is also a white crystalline powder that is easily soluble in water. It is often used as a pH regulator, antioxidant, and an agent to enhance the taste of food. When added to beverages, pastries, and other foods, it can effectively remove bitterness and sourness.
2¡¢ The use of sodium benzoate and potassium sorbate
Sodium benzoate is a widely used preservative that can prevent microbial and bacterial contamination in food, thereby extending the shelf life of food. It is often used in various foods such as pastries, jams, salad dressings, meat products, etc. to prevent food spoilage and spoilage.
Potassium sorbate is a commonly used food additive, mainly used to enhance food taste and improve quality. It can play a role in acidification and swelling during the pastry making process, and can also be used in various foods such as beverages and jellies to enhance taste and flavor.
3¡¢ Safety of sodium benzoate and potassium sorbate
Sodium benzoate and potassium sorbate are both safe food additives when used in moderation, but excessive use may bring some potential health risks. Sodium benzoate has a high content in some immature vegetables and meat products, which may cause adverse reactions such as migraines and allergic reactions. Excessive intake of potassium sorbate may cause digestive system problems such as stomach discomfort and vomiting.
4¡¢ Conclusion
In summary, although sodium benzoate and potassium sorbate are both food additives, their chemical properties and uses are different. Sodium benzoate is mainly used as a preservative, while potassium sorbate is often used to enhance the taste of food. When using these additives, attention should be paid to their reasonable use to avoid potential health risks.
