What are the commonly used desiccants for food

Introduction: the commonly used desiccants for food mainly include quicklime, desiccant, silica gel desiccant, and montmorillonite desiccant The characteristics of these three different types of desiccants will also be different The most widely used desiccant is in food, which can prevent food from spoilage and decay What are the components of food desiccant? What are the hazards of food desiccant What about the knowledge about desiccant? We can learn more about it through the safety net of Baibai Food desiccant is actually to reduce the humidity in food and prevent food from corruption and deterioration I want to know more about it Commonly used desiccants in food are calcium oxide and silica gel Calcium oxide, also known as quicklime, is a white or gray block, which has a strong function of absorbing water in the air There are generally three kinds of 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 To sum up, "what are the commonly used desiccants for food?" I will talk about it today The desiccants in food are generally free of poison, tasteless, corrosive and environmental pollution In the laboratory, the desiccants used mainly include concentrated sulfuric acid and alkali lime, which will cause certain harm Although food desiccants will not produce It's toxic, but children try to stay away from these food dryers To learn more about food additives and food safety, you can directly log in to Baibai safety net Editor in charge: he xianrob
