We vacuum seal microgreens to help extend their freshness longer.
Everybody knows that exposing food to air (especially oxygen) causes it to deteriorate.
Vicki first learned about packing salad greens in a vacuum through Paula Rhodes’ SaladInAJar.com.
After acquiring a hand-held vacuum sealer and an attachment to cover wide mouth canning jars, Vicki put the idea to the test.
She found that by vacuum sealing cut lettuce in wide mouth quart jars, she could extend its crispness and edibility by a number of days, when compared to leaving it in any other kind of non-vacuum packaging (like a sealed plastic bowl or plastic bag).
Since microgreens are so delicate, their deterioration may happen even faster than that of cut up head lettuce. (We are currently testing them side-by-side.)
However, as the photo above shows, we have experimented with vacuum sealing microgreens in both pint and quart canning jars.
To vacuum seal microgreens,
- loosely pack microgreens (or cut up microgreens) in the size jar of your choice (we prefer wide mouth jars in both pint and quart sizes);
- apply to the jar top or brim a properly fitting canning lid that has not undergone a cooked canning process;
- cover the lid on the jar with a jar kit (attachment);
- cover the hole on the jar kit (attachment) with the sealer;
- press the button on the sealer until the jar has been vacuum packed;
- remove the sealer and jar kit; and
- apply a jar band to help protect the lid from becoming dislodged.
