Why is the desiccant in snacks hot

Introduction: the desiccant in snacks includes quicklime and silica gel If quicklime is used, it will mature after encountering water During neutralization reaction, it will generate a lot of heat, which will lead to explosion We usually eat small food will include some desiccants, then these desiccants are mainly food desiccants with quicklime and silica gel as raw materials Because the source of quick lime desiccant is relatively convenient, so the price will be relatively low Many food manufacturers will use quick lime to make food desiccant, but it is also prone to some dangerous performance So, why is the desiccant in snacks hot? Let's welcome Taiwan safety net to give you a detailed introduction There is more than one kind of desiccant in snacks, among which silica gel desiccant is widely used in recent years due to its advantages of non-toxic, tasteless, non corrosive, stable shape, good moisture absorption capacity, etc silica gel desiccant will not react when adding water The desiccant with explosion should be the desiccant containing lime, Because of its low price and strong water absorption, it is used as a food desiccant, but the lime desiccant will emit a lot of heat when encountering water However, to reach the degree of explosion, two conditions must be met: one is sealed space; the other is to generate a lot of heat Only put this kind of desiccant into a small container, add a small amount of water (if the water is full, there is no air in the bottle) and tighten the lid, the lime will heat up when encountering the water, heat the air in the bottle, the air will expand to a certain extent, the bottle will burst.. Therefore, it is not any desiccant, which will explode if thrown into the water casually After the quicklime is inadvertently put into the eye, It is very easy to damage the conjunctiva of the eye In serious cases, it may cause blindness Therefore, parents should not let their children touch them after buying back packaged food with desiccant To sum up, "why is the desiccant in snacks hot?" as mentioned here today, when children eat small food in their lives, they must avoid eating lime desiccant by mistake, which can be directly diluted with water and milk and then drunk, and can be discharged in time Quick lime desiccant will cause great harm, so parents and friends must pay attention to the storage and handling methods of these desiccants To learn more about food additives and food safety, you can directly log in to Baibai safety net Editor in charge: he xianrob
