苯甲酸钠是很常用的食品防腐剂，有防止变质发酸、延长保质期的效果，在世界各国均被广泛使用。而关于苯甲酸钠建议了解这些内容，下面就让氢氧化钾厂家为您解答一番。
Sodium benzoate is a very common food preservative, which has the effect of preventing deterioration and acidification and extending the shelf life. It is widely used in the world. As for sodium benzoate, it is suggested to understand these contents. Let the potassium hydroxide manufacturer answer them for you.
苯甲酸钠的作用是什么？
What is the role of sodium benzoate?
苯甲酸钠也是重要的酸型食品防腐剂。使用时转化为有效形式苯甲酸。使用范围及使用量参见苯甲酸。此外，也可作为饲料的防腐剂。该品用作食品添加剂（防腐剂）、医药工业的杀菌剂、染料工业的媒染剂、塑料工业的增塑剂，也用作香料等有机合成的中间体。
Sodium benzoate is also an important acid type food preservative. When used, it is converted to benzoic acid in its effective form. See benzoic acid for the scope and amount of use. In addition, it can also be used as a feed preservative. The product is used as food additive (antiseptic), fungicide in pharmaceutical industry, mordant in dye industry, plasticizer in plastic industry, and intermediate in organic synthesis such as perfume.
苯甲酸钠的毒性是多少？
What is the toxicity of sodium benzoate?
根据上述毒理学试验评估苯甲酸钠毒性可知：苯甲酸属于低毒类物质（每日容许摄入量ADI为0-5mg/kg；半数致死剂量LD50为2530mg/kg）。在美国，苯甲酸钠的大允许使用量为0.1g/kg。
According to the toxicity evaluation of sodium benzoate by the above toxicology test, it can be seen that benzoic acid belongs to low toxic substance (ADI is 0-5mg / kg; LD50 is 2530mg / kg). In the United States, the maximum allowable amount of sodium benzoate is 0.1g/kg.

苯甲酸钠怎么排出体外？
How is sodium benzoate discharged from the body?
苯甲酸进入机体后，主要与甘氨酸结合以马尿酸的形式排出体外，也有一小部分与葡糖醛酸结合为1-苯甲酰葡糖醛酸而排出，苯甲酸钠摄入量较少时，在10－14小时内便可从体内全部排出，不会有积蓄作用。其毒性主要在肝脏内化解，然后经肾脏排出。
After benzoic acid enters the body, it is mainly combined with glycine to be excreted in the form of hippuric acid. A small part of it is also excreted by combining with glucuronic acid to form 1-benzoylglucuronic acid. When sodium benzoate is consumed less, it can be completely excreted from the body within 10-14 hours without accumulation. Its toxicity is mainly internalized in the liver and then excreted by the kidney.
苯甲酸钠是防腐剂吗？
Is sodium benzoate a preservative?
苯甲酸钠的使用（以苯甲酸计）可参照GB2760—2014中苯甲酸的使用规定。苯甲酸钠在国标中有严格的使用范围和使用剂量要求，远低于前面的毒理学数据。其实消费者可以放心食用含有防腐剂的食品。
The use of sodium benzoate (calculated as benzoic acid) can refer to the use regulations of benzoic acid in gb2760-2014. Sodium benzoate has strict use range and dosage requirements in the national standard, which is far lower than the previous toxicological data. In fact, consumers can safely eat food containing preservatives.
苯甲酸钠的用途？
