Store your kimchi in an airtight container specifically designed for strong-smelling foods, or double-bag it in heavy-duty freezer bags, ensuring all air is removed before sealing. This will contain the odor while allowing fermentation to continue.
Kimchi's pungent aroma comes from the fermentation process, which produces volatile sulfur compounds. While these compounds are essential for the characteristic kimchi flavor, they can easily permeate your refrigerator. To minimize the smell without halting fermentation, you need to create a robust barrier.
Here's a step-by-step approach:
Choose the Right Container: Opt for a container made of glass or BPA-free plastic that has a tight-fitting, airtight lid. Some containers are specifically marketed as 'kimchi containers' and are designed to minimize odor leakage.
Double Bagging (Alternative): If you don't have an airtight container, use heavy-duty freezer bags. Place the kimchi in one bag, squeeze out as much air as possible, and seal it tightly. Then, place that bag inside another freezer bag, again removing as much air as possible before sealing.
Proper Sealing: Ensure the container lid is properly sealed or the bags are tightly closed. A poor seal will allow the odor to escape.
Activated Charcoal (Optional): Place an open container of activated charcoal near the kimchi container in your fridge. Activated charcoal is excellent at absorbing odors.
Regular Cleaning: Periodically clean your refrigerator with a solution of baking soda and water to help neutralize any lingering odors.
Avoid using plastic containers that are not specifically designed for food storage, especially for strong-smelling foods like kimchi. The plastic can absorb the odor, making it difficult to remove even after washing, and potentially affecting the taste of other foods stored in the same container later.
