To prevent the attack of microbes the vegetables and fruits are sealed in [[1]]

Airtight packaging is used to keep vegetables and fruits fresh for a longer period and prevent the attack of microbes. Airtight packaging helps to create a barrier between the food and the outside environment, which helps to prevent contamination by bacteria, mold, or other harmful microorganisms. This can be done through the use of various methods, such as vacuum sealing or the use of airtight packets. Additionally, keeping the food in the refrigerator or freezer after packaging can further enhance its preservation and prevent microbial growth. Other methods like canning, fermentation, and dehydration are also used for food preservation but may not necessarily involve airtight packaging as the primary method for preventing microbial attack on fruits and vegetables.
