天然的柠檬酸存在于水果中，如柠檬、柑橘等。人工合成的柠檬酸是用砂糖、糖蜜、淀粉、葡萄等含糖物质发酵而制得的，可分为无水和水合物两种。纯品柠檬酸为无色透明结晶或白色粉末，无臭，有一种诱人的酸味，那么，人工合成的柠檬酸有毒吗？下面顺酐生产厂家为您分析：

Natural citric acid is present in fruits such as lemons, oranges, etc. Artificial citric acid is produced by fermentation of sugar containing substances such as sugar, molasses, starch, grapes, etc. It can be divided into anhydrous and hydrated forms. Pure citric acid is colorless, transparent crystal or white powder, odorless, and has an attractive sour taste. So, is artificially synthesized citric acid toxic? The manufacturer of maleic anhydride will analyze for you:

柠檬酸是食品加工业中很重要的食品添加剂，也广泛应用于医药、染料及其他工业。柠檬酸生产有两条途径，一条是以淀粉及糖类为原料,用微生物发酵方法来制取，是从含酸分丰富的原料中提取，特别是在果品加工中进行综合利用如制梅胚后排出的咸酸汁液，其含酸量可达4—5%，制柑橘胚后排出的咸酸汁液都是提取柠檬酸很好原料。

Citric acid is an important food additive in the food processing industry and is also widely used in pharmaceuticals, dyes, and other industries. There are two ways to produce citric acid. One is to use starch and sugars as raw materials and use microbial fermentation methods to extract them. It is extracted from raw materials with rich acid content, especially for comprehensive utilization in fruit processing. For example, the salty acid juice discharged after plum embryo production can have an acid content of 4-5%, and the salty acid juice discharged after citrus embryo production is a good raw material for extracting citric acid.

柠檬酸之所以被作为食品添加剂，只是因其具有特殊的酸味。过量使用柠檬酸的害处是影响食品的口感，而非给人体带来明显的危害。当然，胃溃疡、胃酸过多、龋齿和糖尿病患者是不宜经常食用柠檬酸的。据文献报道，柠檬酸具有收缩、增固毛细血管并降低其通透性的作用，还能提高凝血功能及血小板数量，缩短凝血时间和出血时间，具有一定的止血作用。

The reason why citric acid is used as a food additive is simply because it has a special sour taste. The harm of excessive use of citric acid is that it affects the taste of food, rather than causing significant harm to the human body. Of course, patients with gastric ulcer, excessive gastric acid, dental caries and diabetes should not often eat citric acid. According to literature reports, citric acid has the effect of contracting, consolidating capillaries, and reducing their permeability. It can also improve coagulation function and platelet count, shorten coagulation and bleeding time, and have a certain hemostatic effect.

柠檬酸属于可以食用的一种酸类，一般情况下，只要不过量对人体是没有毒的。在一些食物中如果加入柠檬酸的话，不但可以促进人体的新陈代谢，而且还能提高食物的口感，增强人的食欲。柠檬酸属于规定可以使用的食品添加剂，但是如果长期的吃含有柠檬酸的食品的话，也会对人体产生一些不良的影响的，尤其是对正在成长中的孩子来说，会让孩子容易兴奋，造成钙流失比较多，所以要适可而止。

Citric acid is an edible acid that is generally not toxic to the human body as long as it is not excessive. If citric acid is added to some foods, it can not only promote human metabolism, but also enhance the taste of the food and enhance people's appetite. Citric acid is a food additive that can be used according to national regulations. However, if food containing citric acid is consumed for a long time, it can also have some adverse effects on the human body, especially for growing children, which can make them easily excited and cause more calcium loss. Therefore, it is necessary to stop it appropriately.

朋友们一定要注意柠檬酸之所以被作为食品添加剂，只是因其具有特殊的酸味。过量使用柠檬酸的害处是影响食品的口感，而非给人体带来明显的危害。当然，胃溃疡、胃酸过多、龋齿和糖尿病患者是不宜经常食用柠檬酸的。您对该产品有需求就来我们网站http://www.jnjhhg.cn进行咨询了解吧！

Friends, it is important to note that citric acid is used as a food additive only because of its unique sour taste. The harm of excessive use of citric acid is that it affects the taste of food, rather than causing significant harm to the human body.
