苯甲酸鈉是一種鹽，可以在一些食物中自然產生，但更多是化學生產并作為防腐劑添加到食品中。作為防腐劑使用時，已經廣泛使用在食品、日用品、藥品和美容護膚品中。

Sodium benzoate is a salt, which can be naturally produced in some foods, but it is more chemically produced and added to food as a preservative. When used as a preservative, it has been widely used in food, daily necessities, drugs and beauty and skin care products.

在生活中我們應該注意食品標簽上是否含有它。由于苯甲酸鈉有殺死細菌，酵母菌和真菌的作用，它更常作為防腐劑用于酸量高的食品，因為苯甲酸鈉只有在酸堿度（pH值）少于3.6的時候才會發揮作用。因此它在汽水，醋，果汁，以及沙拉醬等混合成分里效果好。此外，它還用來阻止葡萄酒發酵過程。

In life, we should pay attention to whether food labels contain it. Because sodium benzoate can kill bacteria, yeasts and fungi, it is more often used as a preservative in foods with high acid content, because sodium benzoate only works when the pH (PH) is less than 3.6. Therefore, it works well in mixed ingredients such as soda, vinegar, fruit juice, and salad dressing. In addition, it is also used to prevent the wine fermentation process.

蘋果，李子和小紅莓等水果可以自然產生苯甲酸鈉。此外，丁香，肉桂少數甜性香料也含有少量苯甲酸鈉。但這些食品包含這種化學物質不是為了防護自己。

Fruits such as apples, plums and cranberries can naturally produce sodium benzoate. In addition, a few sweet spices such as clove and cinnamon also contain a small amount of sodium benzoate. But these foods contain this chemical not to protect themselves.

可以嘗出食品是否添加了苯甲酸鈉，實際上75%以上的人可以做到這一點。但這些人會以不同方式描述苯甲酸鈉。有些人說它發苦，或帶有鹽味，而有些人則認為它有點甜。由于我們已經習慣于喝軟飲料，因此很少有人注意到這種防腐劑。

You can taste whether sodium benzoate is added to food. In fact, more than 75% of people can do this. But these people will describe sodium benzoate in different ways. Some people say it's bitter or salty, while others think it's a little sweet. Since we are used to drinking soft drinks, few people pay attention to this preservative.

苯甲酸鈉與維生素C混合涉及的健康危害問題已經引起了人們注意。當這兩種物質混合后，會產生化學試劑苯，但苯甲酸鈉本身不是致癌物質。

The health hazards involved in the mixing of sodium benzoate and vitamin C have attracted people's attention. When these two substances are mixed, the chemical reagent benzene will be produced, but sodium benzoate itself is not a carcinogen.

苯甲酸鈉對人體有害，因為苯甲酸鈉與人體內的胃酸會發生反應，生成苯甲酸。苯甲酸有一定的毒性，長期飲用會引起人慢性苯中毒。慢性苯中毒的癥狀主要表現為神經衰弱，比如頭痛、頭暈、記憶力減退、、乏力等；同時，病人還會出現白細胞減少，嚴重的還會造成再生障礙性貧血。

Sodium benzoate is harmful to human body, because sodium benzoate will react with gastric acid in human body to produce benzoic acid. Benzoic acid has certain toxicity, and long-term drinking will cause chronic benzene poisoning. The symptoms of chronic benzene poisoning are mainly neurasthenia, such as headache, dizziness, memory loss, insomnia, fatigue, etc; At the same time, the patient will also have leucopenia, and even cause aplastic anemia in severe cases.

氫氧化鉀廠家提醒您，含有苯甲酸鈉食品和用品有：苯甲酸鈉也叫做E211。苯甲酸鈉作為防腐劑添加到需要長期常溫保存的食品中：

Potassium hydroxide manufacturers remind you that foods and supplies containing sodium benzoate include sodium benzoate, also known as E211. Sodium benzoate is added as a preservative to foods that need to be stored at room temperature for a long time:

醬油、醬菜、果醬、腐乳、果子露、汽水、各種飲料、罐頭，日用品中的漱口水、牙膏、洗發水、護膚液和除臭劑、美容產品、印泥、漿糊及粘膠劑及各種藥品都包含苯甲酸鈉。

Soy sauce, pickles, jam, fermented bean curd, fruit dew, soft drinks, various beverages, cans, mouthwash, toothpaste, shampoo, skin care fluid and deodorant in daily necessities, beauty products, inkpad, paste and adhesive, and various drugs all contain sodium benzoate.

如果想避免苯甲酸鈉，應閱讀成分標簽。注意“”苯甲酸”“苯”“苯甲酸鈉”或“本酸鹽”等詞匯，停止消費這類飲料，盡量避免這種化學品的攝入是明智做法。更多相關事項就是來網站http://www.yiqijieneng.cn咨詢吧。
