Should green beans be blanched before vacuum sealing?

Yes, you should blanch green beans before vacuum sealing them for long-term freezer storage to preserve their color, flavor, texture, and nutrients, preventing them from becoming mushy or developing off-flavors; skipping blanching leads to a shorter shelf life and lower quality, though some people report success freezing them raw for shorter periods.

If you don't blanch greens before freezing, they will likely develop a mushy texture, lose their vibrant color (turning dull or brownish), and taste "off," with a noticeable decline in quality over time because the enzymes that cause spoilage aren't deactivated, leading to faster nutrient and flavor loss, even in the freezer. While not dangerous, the end result is a less palatable product, making blanching crucial for preserving color, taste, and nutrients for long-term storage.
