Kitchen methods to improve food preservation and reduce waste

Various household methods can be used to extend the freshness of produce and reduce food waste. To manage moisture in refrigerator crisper drawers, placing paper towels at the bottom can help absorb excess humidity. This is particularly effective for leafy greens, which are susceptible to softening and deterioration when exposed to standing water or condensation. For best results, the drawer should be cleaned before adding the towels, and the towels should be replaced regularly once they become saturated.

To prevent cut avocados from browning due to oxidation, several techniques are available. Applying a light coating of cooking oil to the exposed flesh can create a barrier that limits oxygen contact with the fruit's enzymes. Other common methods include pressing plastic wrap directly onto the surface to minimize air circulation or applying acidic juices, such as lemon or lime, to slow the enzymatic browning process.
