Can you vacuum seal fresh veggies?

In this blog we examine the question, “Can you vacuum seal fresh veggies?”

The answer is yes, you can absolutely vacuum seal vegetables!

However, you need to prepare your veggies correctly BEFORE freezing in order to preserve texture, flavour and nutritional content, while taking advantage of a longer shelf life.

Below is Pac Food’s Veggie Vacuum Sealing Guide outlining the dos and don’ts of vacuum sealing vegetables, plus which vacuum sealing machines, bags and rolls work best for fresh produce.

Vacuum Sealing Fresh Vegetables

Before vacuum sealing anything preparation is key. For produce, this means cutting your produce into pieces which are suitable for sealing.

While certain veggies (such as capsicum and green beans) can be sealed fresh, if you intend to freeze your vacuum sealed produce, they need to be blanched first.

How do you blanch vegetables?

Blanching is the process of scalding a food (typically fresh produce such as fruit or vegetables) in steam or boiling water (1-4 mins) and then running under cold water and drying prior to being sealed and frozen.

This is done to maintain colour, texture, vitamins and flavour.

Different vegetables have different recommended blanching times to ensure the best possible results. You’ll find a chart of blanching times down further in this blog.

Which Vegetables Can I Vacuum Seal?

  • Can you vacuum seal potatoes?

Yes, you can vacuum seal potatoes! How you intend to use them later will guide you as how best to prepare them. For example:

  • You can store them as French fries which have been fried briefly.[GF1] 
    • You can mash them and store them as patties. Freeze until solid then vacuum seal.
    • Potatoes can be cooked using the sous vide method.
    • You can dehydrate your potatoes as slices or cubes and vacuum seal.
  • Can you vacuum seal herbs?

While a number of herbs are tastiest when picked fresh from the garden, you can actually preserve a selection of herbs by blanching and vacuum sealing them. These include:

  • Parsley
  • Mint
  • Chives
  • Basil
  • Dill

Expert tip – Herbs should not be vacuum sealed when wet or even slightly damp as they will become soggy.

  • Can you vacuum seal lettuce?

Yes – even ‘softer’ produce lettuce can be vacuum sealed.

Once this is done it can be stored in the refrigerator for a longer shelf life, which is typically up to about 2 weeks.

  • Can you vacuum seal cruciferous vegetables?  (e.g. cabbage, broccoli, cauliflower, kale etc)

Cruciferous vegetables will spoil if they’re vacuum sealed without being blanched, so don’t forget this important step first. Blanching times vary between each type.

Some of these times are outlined in the chart from the National Centre for Home Food Preservation below:

What vegetables should NOT be vacuum sealed?

We do not recommend vacuum sealing the next few foods.

  • Can you vacuum seal onions?

Onion, along with garlic, shouldn’t be vacuum sealed at all.

Vacuum sealing fresh onions, garlic and mushrooms can lead to bacteria growth which can cause botulism – a very dangerous, potentially lethal, disease.

  • Can you vacuum seal mushrooms?

It is not recommended. A dangerous chemical reaction takes place when air is removed, causing these foods to be dangerous if ingested.
