苯甲酸钠是一种防腐剂，因为苯甲酸钠易穿透细胞今日细胞体内，抑制细胞膜对氨基酸的吸收，从而起到食物防腐的作用。下面氢氧化钾厂家概述苯甲酸钠的适用范围及注意事项。

Sodium benzoate is a preservative, because sodium benzoate easily penetrates cells today, inhibits the absorption of amino acids by cell membranes, and thus plays a role in food preservation. The following potassium hydroxide manufacturers outline the scope of application and precautions of sodium benzoate.

适用范围

Scope of application

①在一般汽水、果汁中使用时，应在配制糖浆时添加。如先将糖溶化、煮沸、过滤后，一边搅拌一边将苯甲酸钠投入糖浆中。也可在溶糖时添加。待苯甲酸钠充分溶解后，即可分别先后加入悬浊剂及柠檬酸。应注意，苯甲酸钠、柠檬酸、悬浊剂须分别先后加入，尤其是苯甲酸钠与柠檬酸，如果同时加入，就会出现絮状物。

① When it is used in ordinary soda water and fruit juice, it should be added in the preparation of syrup. For example, after the sugar is dissolved, boiled and filtered, sodium benzoate is put into the syrup while stirring. It can also be added when sugar is dissolved. After the sodium benzoate is fully dissolved, the suspension agent and citric acid can be added successively. It should be noted that sodium benzoate, citric acid and suspension agent must be added successively, especially sodium benzoate and citric acid. If they are added at the same time, flocs will appear.

②用于酱油中，苯甲酸钠要在加热工序中添加。通常是将生酱油放入装置，加热温度时（一般在65℃~75℃，根据季节与品质具体掌握）添加苯甲酸钠。苯甲酸钠可先用适量的热水或近80℃的三淋油溶解后加入。

② For soy sauce, sodium benzoate should be added in the heating and sterilization process. Generally, the raw soy sauce is put into the sterilization device, and sodium benzoate is added when it is heated to the sterilization temperature (generally 65 ℃~75 ℃, depending on the season and quality). Sodium benzoate can be dissolved with proper amount of hot water or triple drenching oil at nearly 80 ℃ before being added.

③用于醋中，应在淋出、调整好酸度后添加

③ For vinegar, it should be added after pouring and adjusting the acidity

使用注意事项

Precautions

苯甲酸在常温下难溶于水，在空气中微挥发，有吸湿性，大约常温下0.34g/100ml;但溶于热水；也溶于乙醇、氯仿和非挥发性油。苯甲酸钠大多为白色颗粒，无臭或微带安息香气味，味微甜，有收敛性；易溶于水（常温）53.0g/100ml左右，PH在8左右；

Benzoic acid is insoluble in water at room temperature, slightly volatile in air, hygroscopic, about 0.34g/100ml at room temperature; But soluble in hot water; It is also soluble in ethanol, chloroform and non-volatile oil. Sodium benzoate is mostly white granules, odorless or slightly with a restful aroma, slightly sweet and convergent; Easily soluble in water (normal temperature) about 53.0g/100ml, PH about 8;

（1）苯甲酸钠为强碱弱酸盐，其水溶液显碱性，pH等于8。在酸性溶液中水解成苯甲酸，溶解度降低。

(1) Sodium benzoate is a strong base weak acid salt, and its aqueous solution is alkaline, with pH equal to 8. Hydrolyze to benzoic acid in acid solution, and the solubility decreases.

（2）可单独使用，也可混用，1g苯甲酸相当于1.18g苯甲酸钠。

(2) It can be used alone or mixed. 1g benzoic acid is equivalent to 1.18g sodium benzoate.

使用量

Usage

（1）我国《食品添加剂使用卫生标准》（GB2920-1996）规定：使用苯甲酸钠，亦以苯甲酸计，不得超过用量，详见苯甲酸。

(1) China's Hygienic Standard for the Use of Food Additives (GB2920-1996) stipulates that the use of sodium benzoate is also calculated by benzoic acid, and the dosage shall not exceed the dosage. See benzoic acid for details.

（2）实际使用参考：一般使用方法是加适量水溶解后加入食品中，但具体使用时又可有不同。

(2) Reference for actual use: The general use method is to add an appropriate amount of water to dissolve and then add it into the food, but the specific use may vary.

总之具体可应用于可以应用于酱油、醋、果汁类、果酱类、果子露、葡萄酒、罐头、汽酒、汽水、低盐酱菜、面酱类、桔浆、梨膏糖、蜜饯类、山楂糕、药用糖浆、化妆品等。您有什么不理解的地方欢迎来我们网站http://www.jinhao360.com进行咨询！
