There are right and wrong ways to store your food. For example, some produce must be refrigerated while other types need to be kept at room temperature. Some cooking oils are fine on the countertop, and others should be stored in the fridge. Even some of your expired foods aren't really expired, and you might be using the wrong containers. With food storage at a premium, you don't want to let anything go to waste.

We’ve done the legwork to figure out the right ways to store your food so that it tastes best and lasts the longest. Here are the answers to ten common kitchen storage mistakes.

Expiration dates have less to do with safety than they do quality.

Did you know that there's no national regulation detailing what expiration dates actually mean? Expiration dates often reflect quality control, not safety or nutritional value. How do you know if your food is safe to eat? Read up on USDA guidelines, use your eyes and nose, and follow your gut.

Check the packaging, use your senses, cook food thoroughly, and don't let the perfect become the enemy of the good. A proper understanding of "expiration" dates could drastically cut down on food waste—not to mention wasted money out of your pocket.

Bee's Wrap can be used to store anything from cookies to sandwiches. But not soup... yet.

If you’re sick of throwing away disposable food wrap but still want to keep food fresh, Bee's Wrap might be your answer. This reusable food wrap is made from beeswax and fabric.

It's designed so you can build a sandwich on top of it in your kitchen, then unwrap it to use as a placemat. Bee's Wrap is also ideal for food storage. An avid home baker, creator Sarah Kaeck said it’ll help keep bread crusty and soft. It's also great for wrapping cheese, half of an avocado, half of a lemon, covering jars and bowls (press some Bee's Wrap onto the top of a container and the warmth of your hand will soften the wax just enough to create a seal).

Afterwards, just wash it with cold water (soap is okay, but warm water melts the wax), hang-dry, and use it again. It should last about a year if you use it a few times a week.

Not everything goes in your fridge,

Some foods are actively made worse by refrigeration—onions, potatoes, garlic, avocado, tomatoes, bananas, stone fruit, bread, pastries, melons, spices, honey, peanut butter, apples, coffee, eggs, butter, condiments, dressings, soy sauce and hot sauce should never (or rarely) be refrigerated. Surprised?

Learn why you shouldn't refrigerate these foods.

Some cooking oils are best stored in the cabinet, while others can be refrigerated.

Cooking oils sourced from fruits, vegetables, nuts, and seeds each have different storage needs. Exposure to oxygen, light or heat will subject oil to oxidation, eventually turning it rancid. While some cooking oils can be stored at room temperature, others do best when stored in the fridge.

The best food storage containers we tested were the Pyrex Ultimate.

We tested the best-selling plastic and glass food storage containers on the market to find the best of the lot. We dropped them onto a linoleum floor, froze them, microwaved them, stained them, pried them apart, stacked them back together, and lots more.

Best glass container: Pyrex's Ultimate 10-Piece Glass Storage Set is fully plastic-free—the containers are topped with glass lids trimmed with white silicone. Food won't leak, and the glass won't shatter. While the silicone on the lid will stain, it will come clean after a run in the dishwasher. There's a vent for microwave reheats and, as long as the contents are defrosted, it's also preheated oven safe.

Best plastic container: Rubbermaid's Easy Find Lids containers won't spring a leak unless you shake them violently, and drops aren't a problem unless the container happens to fall on its side or a corner. No plastic container is oven-safe, but the set is marked dishwasher- and microwave-safe, and carries a lifetime warranty. You should avoid freezing this set, as expanding food may pop the lid.

Do you know which vegetables should stay at room temperature, which should be kept inside a crisper drawer, and which should never be stored together? Are you sure?

Do not refrigerate: Potatoes, onions, garlic, winter squash, tomatoes, bananas, peaches, plums, avocados, mangoes, melons, apples, pears, kiwis, and citrus. Exceptions include freezing for smoothies, or refrigerating for brief periods when they're close to spoiling.

Keep separate: Produce that emits high levels of ethylene gas, including ripe bananas, apples, stone fruit (except for cherries), cantaloupe, honeydew melons, mangoes, pears, ripe kiwis, tomatoes, onions, and leeks.

Store alone: Ethylene-sensitive produce, including broccoli, Brussels sprouts, cabbage, carrots, cauliflower, cucumber, eggplant, leafy greens, peas, peppers, squash, sweet potatoes, strawberries, and watermelon.

There are many ways to store a cut avocado, but only one that will actually keep it from browning and preserve the flavor: Leave the pit in an avocado, and tightly wrap the half in plastic wrap to keep the flavor and texture in tact.

Foods in your fridge shouldn't be freezing.

Biting into frozen food that's merely supposed to be refrigerated isn't just annoying: Freezing can completely alter the taste and texture of your food. And it's probably because you’re probably arranging your fridge the wrong way.

Check your fridge's temperature settings: The ideal temperature range for the interior of your fridge is 38-42°F.

Determine problem areas: According to GE, the most common problem areas are the top shelf, the bottom of the fridge (crisper drawers and meat pans), and door shelves.

Avoid vents: Most fridges have a cooling vent above the top shelf. This is where most of the cold air comes from, so keeping food away from here may prevent freezing. (A 5-inch radius should do the trick.)

Adjust your freezer: Turn up your freezer temperature settings, but nothing north of 0°F, which will facilitate bacterial growth and accelerate food spoilage.

Check your ice maker: Make sure that your ice maker is not constantly running. This could make your freezer too cold and subsequently cause your refrigerated foods to freeze.

Stock up your fridge: Refrigerators need to be well-stocked to absorb all of the cold air being vented into the cavity. If it is relatively empty, all of the cold air will sink to the bottom of the cavity and freeze your food. A fully stocked fridge will help maintain temperatures and, as a result, use less energy.

Find out how to arrange your fridge correctly.

If your fridge door won't close, it's probably due to an old, dried-out gasket, the rubber seal that runs along its edge. Luckily, the fix is simple: wash the gasket, and apply petroleum jelly to the rubber to revitalize the old rubber.

A full fridge will help keep the temperature consistent.

Did you know your fridge could actually be making you sick? To keep food out of what the USDA calls "the danger zone," it needs to remain below 40°F. The freezer should to be 0°F to keep freezer burn at bay. If your fridge and freezer are regularly warmer than those temperatures, you’re risking faster spoilage. Here are a few things you can do to keep your fridge properly chilled:

Check to make sure the gasket is in good shape, and seals well. If you can open the door with one finger, your seal isn't tight enough. A leaky seal is an energy waster, and may be a risk to your food.

Dust your refrigerator's cooling coils, if they're visible. You can use a long, skinny brush made for this purpose.

Cover your food. For example, leave eggs in their carton, not in the door.

Keep a full fridge to retain the cold, but leave enough room for air to circulate.
