苯甲酸鈉是很常用的食品防腐劑，有防止變質(zhì)發(fā)酸、延長保質(zhì)期的效果，在世界各國均被廣泛使用。而關(guān)于苯甲酸鈉建議了解這些內(nèi)容，下面就讓氫氧化鉀廠家為您解答一番。
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.
苯甲酸鈉的作用是什么？
What is the role of sodium benzoate?
苯甲酸鈉也是重要的酸型食品防腐劑。使用時轉(zhuǎn)化為有效形式苯甲酸。使用范圍及使用量參見苯甲酸。此外，也可作為飼料的防腐劑。該品用作食品添加劑（防腐劑）、醫(yī)藥工業(yè)的殺菌劑、染料工業(yè)的媒染劑、塑料工業(yè)的增塑劑，也用作香料等有機合成的中間體。
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.
苯甲酸鈉的毒性是多少？
What is the toxicity of sodium benzoate?
根據(jù)上述毒理學(xué)試驗評估苯甲酸鈉毒性可知：苯甲酸屬于低毒類物質(zhì)（每日容許攝入量ADI為0-5mg/kg；半數(shù)致死劑量LD50為2530mg/kg）。在美國，苯甲酸鈉的大允許使用量為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.

苯甲酸鈉怎么排出體外？
How is sodium benzoate discharged from the body?
苯甲酸進(jìn)入機體后，主要與甘氨酸結(jié)合以馬尿酸的形式排出體外，也有一小部分與葡糖醛酸結(jié)合為1-苯甲酰葡糖醛酸而排出，苯甲酸鈉攝入量較少時，在10－14小時內(nèi)便可從體內(nèi)全部排出，不會有積蓄作用。其毒性主要在肝臟內(nèi)化解，然后經(jīng)腎臟排出。
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.
苯甲酸鈉是防腐劑嗎？
Is sodium benzoate a preservative?
苯甲酸鈉的使用（以苯甲酸計）可參照GB2760—2014中苯甲酸的使用規(guī)定。苯甲酸鈉在國標(biāo)中有嚴(yán)格的使用范圍和使用劑量要求，遠(yuǎn)低于前面的毒理學(xué)數(shù)據(jù)。其實消費者可以放心食用含有防腐劑的食品。
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.
苯甲酸鈉的用途？
What is the use of sodium benzoate?
用于醫(yī)藥工業(yè)和植物遺傳研究，也用作染料中間體、殺菌劑和防腐劑。 3防腐劑；抗微生物劑。
It is used in the pharmaceutical industry and plant genetic research, and also as a dye intermediate, fungicide and antiseptic. 3 preservatives; Antimicrobial agents.
苯甲酸鈉液室重要的酸型飼料防腐劑。使用時轉(zhuǎn)化為有效形式苯甲酸。使用范圍及使用量參見苯甲酸。此外，也可作為食品的防腐劑。
