Problems solved by technology

[0004] Commonly used vegetable preservation methods include refrigeration, controlled atmosphere preservation, radiation preservation, chemical agent treatment, etc. In addition, there are hygroscopic and fresh-keeping plastic packaging films for one-time consumption, microwave preservation and electronic technology preservation methods, etc. Some of them have high requirements for equipment conditions. It needs to invest a lot of money, such as cold storage and controlled atmosphere storage. Some chemical residues are more harmful to people's health, such as chemical agent treatment, and some operations are complicated and inconvenient to master, such as radiation preservation.
