苯甲酸鈉是一種防腐劑，因?yàn)楸郊姿徕c易穿透細(xì)胞今日細(xì)胞體內(nèi)，抑制細(xì)胞膜對(duì)氨基酸的吸收，從而起到食物防腐的作用。下面氫氧化鉀廠家概述苯甲酸鈉的適用范圍及注意事項(xiàng)。

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.

適用范圍

Scope of application

①在一般汽水、果汁中使用時(shí)，應(yīng)在配制糖漿時(shí)添加。如先將糖溶化、煮沸、過(guò)濾后，一邊攪拌一邊將苯甲酸鈉投入糖漿中。也可在溶糖時(shí)添加。待苯甲酸鈉充分溶解后，即可分別先后加入懸濁劑及檸檬酸。應(yīng)注意，苯甲酸鈉、檸檬酸、懸濁劑須分別先后加入，尤其是苯甲酸鈉與檸檬酸，如果同時(shí)加入，就會(huì)出現(xiàn)絮狀物。

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用于醬油中，苯甲酸鈉要在加熱工序中添加。通常是將生醬油放入裝置，加熱溫度時(shí)（一般在65℃~75℃，根據(jù)季節(jié)與品質(zhì)具體掌握）添加苯甲酸鈉。苯甲酸鈉可先用適量的熱水或近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，應(yīng)在淋出、調(diào)整好酸度后添加

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

使用注意事項(xiàng)

Precautions

苯甲酸在常溫下難溶于水，在空氣中微揮發(fā)，有吸濕性，大約常溫下0.34g/100ml;但溶于熱水；也溶于乙醇、氯仿和非揮發(fā)性油。苯甲酸鈉大多為白色顆粒，無(wú)臭或微帶安息香氣味，味微甜，有收斂性；易溶于水（常溫）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）苯甲酸鈉為強(qiáng)堿弱酸鹽，其水溶液顯堿性，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）可單獨(dú)使用，也可混用，1g苯甲酸相當(dāng)于1.18g苯甲酸鈉。

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

使用量

Usage

（1）我國(guó)《食品添加劑使用衛(wèi)生標(biāo)準(zhǔn)》（GB2920-1996）規(guī)定：使用苯甲酸鈉，亦以苯甲酸計(jì)，不得超過(guò)用量，詳見(jiàn)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）實(shí)際使用參考：一般使用方法是加適量水溶解后加入食品中，但具體使用時(shí)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.

總之具體可應(yīng)用于可以應(yīng)用于醬油、醋、果汁類、果醬類、果子露、葡萄酒、罐頭、汽酒、汽水、低鹽醬菜、面醬類、桔漿、梨膏糖、蜜餞類、山楂糕、藥用糖漿、化妝品等。您有什么不理解的地方歡迎來(lái)我們網(wǎng)站http://www.fahao168.com進(jìn)行咨詢！
