[Lock & Lock] Smart Keep Fresh Containers


Introducing Lock & Lock’s New Smart Keep Fresh Containers!

You might have spotted these containers on popular Korean YouTube food channels—they've become a must-have among food creators in Korea!

What makes them special?

These containers are engineered to keep fruits and vegetables fresh for up to 31 days!*

How often have you stored half an onion or a piece of lemon in a random container, only to find it spoiled just days later?

That’s because produce continues to “breathe” even after harvesting, releasing ethylene gas, which accelerates ripening and spoilage.

How do Smart Keep Fresh Containers work?

Made with Zeolite material, these containers absorb ethylene gas, slowing down the ripening process and helping to keep produce fresh longer.

The Zeolite also inhibits the growth of bacteria that cause spoilage.

More Fresh-keeping Features

The wavy design at the bottom of each container minimizes direct contact between food and the container, allowing air to flow and reducing moisture build-up.

Plus, after each wash, the absorbed ethylene gas is completely removed, so the containers are reusable and long-lasting.

And yes, these Smart Keep Fresh Containers are BPA-free!

These Smart Keep Fresh Containers are available as individual pieces or in convenient sets.

We recommend starting with a set and adding extra pieces as needed!

Gochujar Editor Note:

*Review the tables below that list out the maximum storage days of various  fruits and vegetables, plus storage tips!

The actual maximum days of freshness will vary depending on refrigerator temperature and how the ingredients were prepped.

Why should fruits and vegetables be stored differently?

Fruits and vegetables are still alive and continue to 'breathe' after being harvested! 

By absorbing and releasing the ethylene gas they release, you can help them stay fresh for a longer time.
