What is vacuum sealing, and how does it help in preserving fresh vegetables?

Vacuum sealing is a method of removing air from a package before sealing it to create an airtight environment. This process significantly reduces the presence of oxygen, which can cause spoilage and degrade the quality of fresh vegetables over time. By eliminating air, vacuum sealing helps prevent the growth of bacteria and mold, extending the shelf life of your produce.

In addition to prolonging freshness, vacuum sealing also helps retain the nutrients, flavor, and texture of vegetables. It locks in freshness and allows for better organization in your refrigerator or freezer, enabling you to store your produce for longer periods without compromising quality. Vacuum-sealed vegetables are perfect for meal prep, ensuring you have ready-to-cook options on hand while minimizing food waste.

How do I prepare fresh vegetables for vacuum sealing?

To prepare fresh vegetables for vacuum sealing, start by washing and drying them thoroughly. Removing dirt and moisture is crucial, as excess moisture can promote spoilage during storage.
