As it can be frustrating to purchase fresh greens only to find them withering away days later, here are some strategies and products designed to keep them fresher for longer. First, thoroughly wash your greens. Fill a bowl with cold water, submerge your greens in it, swish gently while submerged, rinse them out, and spin in your salad spinner or dry on a towel until dry.
1. Rinse
Simple rinsing will only loosen dirt on leafy cooking greens like kale and Swiss chard, so to ensure thorough cleansing, take them outside (or somewhere where water droplets won’t cause issues) and vigorously whip them with a towel in your hands to give them an intensive cleaning.
This “bath” also helps dissolve stubborn deposits of sanonom greens. To make this “bath”, simply bring a pot of clean water to boil, submerge your greens for 30 seconds and rinse well under cold running water before rinsing again with cold water.
2. Dry
Experts agree that the optimal way to wash leafy greens is with cool running water or submersion (for textured leaves), then thoroughly drying them afterwards. Moisture promotes bacteria growth and shortens shelf life, so removing as much as possible from their surfaces is critical. Experts advise avoiding commercial produce washes that leave residues and don’t effectively kill bacteria, as well as adding extra sodium to your diet.
If you prefer dramatic kitchen hacks, spread your washed greens over a clean towel and whip vigorously; ideally outdoors or somewhere where water droplets won’t bother anyone nearby. This speedy drying technique dramatically reduces spoilage without resorting to chemical preservatives.
3. Seal
Kale, Swiss chard and collard greens typically last 10 days when stored properly; however, soft vegetables like baby spinach wilt much faster due to their porous leaves trapping dirt, microbes and pesticide residue – therefore making washing essential.
But avoid commercial produce washes; these leave behind residues that encourage bacterial growth while providing no real protection against spoilage. A simple rinse should suffice for most greens; after drying thoroughly with paper towels or using a salad spinner to help prevent wilting while providing airflow so the microbial playground stays cool – then store in your crisper drawer!
4. Store in the Crisper Drawer
Sturdier greens such as kale, collards and Swiss chard tend to hold up better in the fridge than their more fragile cousins – baby spinach and spring mix. When storing sturdy greens like these in your fridge, avoid washing before storage, as even a quick rinse may encourage bacteria growth that speeds spoilage; rather, wash before use and make sure they dry off completely after each washing session.
Most refrigerators feature one or more crisper drawers designed to create different humidity conditions. Store produce according to its needs; fruits that produce ethylene gas, such as apples and avocados, should go into low-humidity drawers, while foods prone to wilt, such as leafy greens and delicate fruit, can be stored in higher-humidity crispers.
5. Store in the fridge.
Most leafy greens sold in supermarkets are grown and harvested according to the Leafy Greens Marketing Agreement, which mandates rigorous safety practices from growers. This is essential because mishandled vegetables may become contaminated with harmful bacteria that could cause illness if they reach your home.
Refrigeration is the ideal place for green storage; however, if your fridge lacks an appropriate drawer for vegetables and fruit, storing them in your crisper using plastic bags should work just fine as long as no ethylene-producing produce like bananas, tomatoes or avocados is nearby.
6. Store in a Container
Kale and spinach greens require special care to preserve their nutrition and crunchiness, unlike tomatoes that often quickly spoil with moisture, prompting bacteria growth that limits their shelf life and shortening it.
An effective salad spinner is essential in properly drying greens such as Tuscan kale or bunch spinach, where simple rinsing does not dislodge all of the grit that adheres to their leaves. Cassie Johnston, personal chef and cookbook author, highly recommends Vejibag as a breathable bag that keeps spinach fresh for weeks! Simply dampening slightly before filling and placing her greens inside, she stores them in the fridge.
7. Store in a Bag
Heads of lettuce, bundles of kale and other large leafy greens require some basic preparation before being stored in the fridge. Remove ties, discard any brown or soft bits, trim stems before storage and discard ties before moving to storage.
She recommends OXO’s 3-quart salad spinner, as it is powerful yet compact enough to fit in any refrigerator drawer. To maintain optimal airflow and humidity conditions, she lines her container with dry paper towel that she changes periodically as required.
8. Store in a Container with a Paper Towel
For optimal results, store your greens in an airtight glass or plastic container lined with a damp paper towel – this allows them to breathe while also absorbing any extra moisture that accumulates from being in the fridge. Wash produce only before you are ready to consume it; washing speeds up spoilage. This includes pre-bagged greens like baby spinach and kale.
When purchasing fresh leafy greens, opt for the highest-quality options within your budget. Look for growers such as Planted Detroit that harvest and deliver directly to customers, ensuring optimal quality and longevity of product.
9. Store in a Container with a Paper Towel
Detwiler states that for most greens such as arugula and baby spinach, simply rinsing under cool running water will suffice. When washing Tuscan or curly kale or bunch spinach leaves individually to remove grit, soil and microbes, dry them completely using either a salad spinner or paper towel before placing them into your refrigerator.
Moisture causes leafy greens to wilt quickly when exposed to moisture, encouraging bacteria, mould and other pathogens that make them unsafe to consume. Instead of spending your money on commercial produce washes, which may leave residues or prove less effective than cold water washing, consider cold water washing instead.
