苯甲酸钠是一种盐，可以在一些食物中自然产生，但更多是化学生产并作为防腐剂添加到食品中。作为防腐剂使用时，已经广泛使用在食品、日用品、药品和美容护肤品中。
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.
在生活中我们应该注意食品标签上是否含有它。由于苯甲酸钠有杀死细菌，酵母菌和真菌的作用，它更常作为防腐剂用于酸量高的食品，因为苯甲酸钠只有在酸碱度（pH值）少于3.6的时候才会发挥作用。因此它在汽水，醋，果汁，以及沙拉酱等混合成分里效果好。此外，它还用来阻止葡萄酒发酵过程。
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.
苹果，李子和小红莓等水果可以自然产生苯甲酸钠。此外，丁香，肉桂少数甜性香料也含有少量苯甲酸钠。但这些食品包含这种化学物质不是为了防护自己。
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.
可以尝出食品是否添加了苯甲酸钠，实际上75%以上的人可以做到这一点。但这些人会以不同方式描述苯甲酸钠。有些人说它发苦，或带有盐味，而有些人则认为它有点甜。由于我们已经习惯于喝软饮料，因此很少有人注意到这种防腐剂。
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.
苯甲酸钠与维生素C混合涉及的健康危害问题已经引起了人们注意。当这两种物质混合后，会产生化学试剂苯，但苯甲酸钠本身不是致癌物质。
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.

苯甲酸钠对人体有害，因为苯甲酸钠与人体内的胃酸会发生反应，生成苯甲酸。苯甲酸有一定的毒性，长期饮用会引起人慢性苯中毒。慢性苯中毒的症状主要表现为神经衰弱，比如头痛、头晕、记忆力减退、失眠、乏力等；同时，病人还会出现白细胞减少，严重的还会造成再生障碍性贫血。
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.
氢氧化钾厂家提醒您，含有苯甲酸钠食品和用品有：苯甲酸钠也叫做E211。苯甲酸钠作为防腐剂添加到需要长期常温保存的食品中：
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:
酱油、酱菜、果酱、腐乳、果子露、汽水、各种饮料、罐头，日用品中的漱口水、牙膏、洗发水、护肤液和除臭剂、美容产品、印泥、浆糊及粘胶剂及各种药品都包含苯甲酸钠。
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.
如果想避免苯甲酸钠，应阅读成分标签。注意“”苯甲酸”“苯”“苯甲酸钠”或“本酸盐”等词汇，停止消费这类饮料，尽量避免这种化学品的摄入是明智做法。更多相关事项就是来网站https://www.tsswhg.com咨询吧。
