Those Plastic Bags From The Grocery Store Won't Leave Your Produce Fresh
Keeping produce fresher for longer requires a balance of humidity and airflow, and the flimsy produce bags from the grocery store won't do. Here are some better storage options.
Tender veggies like lettuce need ventilation to stay fresh in the fridge, so your best bets are to store them in muslin, cotton, or linen bags, which allow for air circulation.
Produce stored outside the refrigerator, like tomatoes and potatoes, must also be removed from their bags. The bags lock in moisture, which can accelerate spoilage.
Certain fruits and veggies also emit ethylene, a gas that speeds up ripening and decomposing. This is another good reason to use a breathable material and not plastic.
