What is the desiccant in the food packaging bag

Introduction: food packaging bags will be added with some desiccants There are many kinds of desiccants, including silica gel desiccants and fiber desiccants, as well as montmorillonite desiccants and quicklime desiccants In the process of purchasing food, we will find that desiccant is contained in food packaging bags, and it is clearly indicated that it can not be used The main function of desiccant is to prevent moisture and the quality of food from being affected What is the desiccant in food packaging bags? What are the hazards of desiccant What about? Next, please give a detailed introduction to Baibai safety net 1、 Silica gel desiccant is a kind of water-bearing silica with high microporous structure It is colorless, tasteless and nontoxic It has stable chemical properties and good hygroscopic properties It is widely used in instruments, instruments, leather, bags, food, textiles, equipment and instruments, etc Its function is to control the relative humidity of the environment in the process of storage and transportation, so as to prevent articles from moisture, mildew and corrosion 2、 The biggest characteristic of fiber desiccant is that it is made of pure natural plant fiber and refined by special process It saves space and is convenient and practical Its moisture absorption capacity is equal to its own weight, which is much higher than that of other desiccants Because of its moderate price, safety and health, it is the best choice for many health products, drugs and biological desiccants 3、 Montmorillonite desiccant this desiccant is widely used in medical health care, food packaging, optical instruments, electronic products, military products, civil products and other products that cannot be sealed by oil and weather 4、 Quicklime desiccant middle school chemistry class has talked about quicklime, its main component is calcium oxide, through chemical reaction to achieve water absorption, with irreversibility The most common is the use of this kind of desiccant in "snow cake" 5、 Calcium chloride desiccant calcium chloride mainly uses high-quality calcium carbonate and hydrochloric acid as raw materials, and is refined through reaction synthesis, filtration, evaporation concentration, drying and other processes It is used as calcium enhancer, chelating agent, curing agent, desiccant and so on in the food industry The five desiccants mentioned above are quite common Montmorillonite desiccant and quicklime desiccant should not be used for a long time, let alone repeated selection Silica gel desiccant, although not very toxic, can not be used for a long time In the process of using desiccant, the manufacturer must strictly implement the dosage operation of desiccant To learn more about food additives and food safety, you can directly log in to Baibai safety net Editor in charge: he xianrob
