Which can not be used as food desiccant

Introduction: among food desiccants, calcium chloride hexahydrate does not have water absorption, so it can not be used as food desiccant and become food desiccant, mainly including silica gel or alkali lime, plus plant fiber with good water absorption There are many kinds of desiccants Some of them are used in food, while some of them can't be used in food Because food desiccants are mainly used to prevent moisture, some of them don't have water absorption, so they can't be food desiccants Baibai safety net is here to introduce them in detail Which can't be used as food desiccant? Phosphorus pentoxide dissolves in water to produce a lot of heat and phosphoric acid It can not be used as food desiccant because of its strong corrosivity, which is often used as desiccant of gas and liquid Concentrated sulfuric acid has water absorption, but concentrated sulfuric acid has strong corrosivity, so it can not be used as food desiccant Caustic soda can not be used as food deoxidizer or food desiccant; It can not be used as food deoxidizer There are three kinds of desiccants that can be used as food desiccants: 1 The main component of quicklime desiccant is calcium oxide, whose water absorption capacity is achieved through chemical reaction, so water absorption is irreversible Regardless of the external environment humidity, it can maintain more than 35% moisture absorption capacity of its own weight, which is more suitable for low temperature preservation, with excellent drying and moisture absorption effect and low price Can be widely used in food, clothing, tea, leather, shoemaking, electrical and other industries 2 Silica gel desiccant this desiccant is a kind of silica gel with high microporous structure It is non-toxic, tasteless, odorless, stable in chemical properties and has strong moisture absorption performance Therefore, it is widely used in the storage and transportation of instruments, meters, equipment and instruments, leather, bags, shoes, textiles, food, medicine, etc to control the relative humidity of the environment, so as to prevent the articles from getting damp, mildew and corrosion 3 Montmorillonite desiccant this desiccant uses pure natural raw material bentonite, green, non-toxic and tasteless, no harm to human body It has good adsorption performance at room temperature and general humidity, with adsorption activity, static dehumidification and odor removal Not only the adsorption speed is fast, the adsorption capacity is high and non-toxic, tasteless, non-contact corrosive, no environmental pollution, especially applied to food packaging, harmless to human body Scope of application: it is widely used in products that cannot be sealed with oil seal or gas phase, such as optical instruments, electronic products, medical health care, food packaging and dry air sealing of military and civil products The desiccants in food are generally non-toxic, tasteless, non-contact corrosive and non environmental pollution; while the laboratory desiccants such as concentrated sulfuric acid, alkali lime and so on are too dangerous, but they also have advantages, such as fast water absorption, high efficiency, low price and so on To sum up: "which can not be used as food desiccant" Today, I'm going to talk about it Through the above understanding, we are familiar with food desiccant Then we will all come into contact with food desiccant in our daily life We must pay attention to the scope of application of food desiccant, and try not to let children touch food desiccant, so as not to cause the phenomenon of eating by mistake To learn more about food additives and food safety, you can directly log in to Baibai safety net Editor in charge: he xianrob
