Foreword: In modern life, with a long history of food production and food processing, people pay attention to food preservation slowly, in order to achieve food preservation, preservation, and extend the shelf life of food and the shelf life of merchants. Various technologies such as refrigeration to ice storage, irradiation, etc. are used. Nowadays, the more convenient and affordable technology is to use deoxidizer preservation method. What is the difference between food deoxidizer and desiccant? What are the food deoxidizers?
Oxygen is one of the main factors that cause food spoilage. Fat in food will lose its nutritional value when it meets oxygen. Most microorganisms can grow well in oxygen. Microorganisms attach to the surface of food and absorb with oxygen. Its nutrients and vitamins cause food to spoil. As a food preservative, the deoxidizer is packed in the same container as the food. The deoxidizer absorbs the oxygen in the container and makes the container anaerobic so that the food can be stored for a longer period of time. However, the raw material of the deoxidizer must have side effects such as stable reaction, no strange smell and no harmful gas generation, and it is harmless to the human body in case of accidental ingestion. The commonly used reaction principle of deoxidizer is iron powder oxidation reaction, generally in the form of belt, the oxidation reaction of iron powder and oxygen that reduces the oxygen concentration to 0.01%.
Desiccant, literally means drying and absorbing water. Absorb the excess moisture inside the product package, and give the product a dry storage environment. For example, the silica gel environmentally friendly desiccant can be recycled. After one time, it can be dried and reused again. The same adsorption effect is the same as the first time. .
Nowadays, many desiccant explosions and food deoxidizers have been consumed. Similar accidents have occurred to children. This is a serious challenge for children and parents, so in life, parents need to sort out what they bought outside. Desiccant and deoxidizer in commodities, food, etc., to avoid accidents on children.
