Can high purity industrial carbon dioxide replace food grade carbon dioxide?

Although both high purity industrial carbon dioxide and food grade carbon dioxide belong to high purity carbon dioxide, their preparation methods are completely different. Food grade carbon dioxide:Carbon dioxide produced in the process of alcohol fermentation is made into liquid carbon dioxide by washing, removing impurities and pressurizing. High-purity industrial carbon dioxide: carbon dioxide gas produced during high-temperature calcination of limestone (or dolomite), made into gaseous carbon dioxide by water washing, decontamination and compression.

High purity carbon dioxide is a pure chemical substance that contains no impurities and is therefore widely used in many applications. However, high purity industrial carbon dioxide is not suitable for food processing. Food grade carbon dioxide is a special type of carbon dioxide that is rigorously processed and purified to ensure that it meets food safety standards. Therefore, food grade carbon dioxide is specialized for food production and can meet food safety and quality requirements.

Food grade carbon dioxide plays an important role in food processing. It is widely used in the production process of carbonated beverages, beer, bread, pastry and other foods. Food grade carbon dioxide can not only adjust the taste and texture of food, but also increase the shelf life and stability of products. At the same time, food grade carbon dioxide is also used in food packaging, which helps to extend the shelf life of food products and maintain their freshness and nutritional value.

In contrast, high-purity industrial carbon dioxide does not have the high purity and safety required for food-grade carbon dioxide. It may contain a number of impurities, such as heavy metals, oxygen, and moisture. These impurities have potential impact on food quality and safety. Therefore, in order to ensure food safety and quality, using food grade carbon dioxide is a necessary choice.

In summary, high purity industrial carbon dioxide and food grade carbon dioxide differ somewhat in nature and use. High purity industrial carbon dioxide is suitable for many other fields, while food grade carbon dioxide is specialized for food production. Therefore, when choosing carbon dioxide gas, the right type should be selected according to specific needs and requirements to ensure the safety and quality of food.
