Here’s why Costco’s avocados last longer than others

As if Costco wasn’t enough of a magical place (even professional chefs love Costco), the shelf life of their avocados will have you running to, well, the shelves. Thanks to the store’s recent collaboration with Apeel Sciences, the shelf life of Costco’s avocados has doubled. So you can finally make homemade guacamole without worrying about the timing of your recently purchased avocados.

Pro tip: Avocados typically last 4-7 days at room temperature. Here’s how long your fresh produce will keep.

How did they do that?

It’s all in the peel! Apeel Sciences has created a plant-based outer peel called Apeel that will extend the shelf life of multiple fruits and vegetables. The peel is made from lipids and glycerolipids—natural fats found in fruits and vegetables. The peel doubles the life of a food product by holding in the moisture inside the fruit or vegetable and keeping the extra oxygen out. The added oxygen is what spoils a food faster, so Apeel slows down the process by reducing oxygenation. (Here’s how to tell if an avocado is ripe.)

10 Kirkland items you should always buy at Costco

Almonds

Health experts can’t stop raving about the benefits of nuts, but man, are they expensive—and Costco agrees. The warehouse store reportedly stopped selling other brands almost entirely when they couldn’t justify how high their prices had gotten. Now you can get a massive three-pound bag of Kirkland Signature almonds for just $13, which isn’t much more than you’d normally pay for a Blue Diamond bag almost half its size. Stock up on these other 15 foods nutritionists always buy at Costco.

Bacon

When Consumer Reports put different bacon brands to the test several years ago, Kirkland Signature soared above the rest, thanks to its crispy texture and smoky-sweet flavor—which is even more impressive considering its low price. Make room in the freezer, because this bulk buy is no joke: Four pounds for $13.69. Plus, learn the secrets behind Costco’s famous $4.99 rotisserie chicken.

Liquor

Across the board, Costco’s value-sized bottles of booze get rave reviews. Its vodka in particular has garnered a cult following, with rumors swirling that it shares the same water source as Grey Goose. The luxury vodka brand denies those claims, but that’s not necessarily a bad thing—the cheap Kirkland version actually outshines Grey Goose in taste tests. Just $25 for 1.75 liters of high-quality liquor? Can’t beat that.

Maple syrup

In a Consumer Reports test, Kirkland’s pure maple syrup was the cheapest option ($0.75 per serving) and still managed to score stellar reviews. Testers deemed its taste “very good,” while the priciest choice in its category, Camp Pure Maple Syrup—which costs almost three times more per ounce—was only rated “good.” Learn more Costco secrets revealed by a former employee.

Pistachios

No matter how tasty they are, it can be hard to justify the price of pistachios—unless you’re at Costco. At face value, a $15 bag seems like a lot, but you’ll change your mind when you see the three-pound package you get. For comparison, a two-pound bag of Wonderful pistachios costs $13 on Amazon. Really, you can’t go wrong with any Kirkland nuts, so stock up on walnuts and mixed nuts too.

Plastic wrap

Kirkland’s food wrap gets high marks for its durability, so the low price is just the icing on the cake. Paying less than $10 for two 750-square-foot rolls, you won’t need to stock up on plastic wrap again for a long time. You should also always stock up if you see this symbol on a Costco price tag.

Quinoa

With more protein and fiber than white rice, quinoa has unsurprisingly gone from food fad to kitchen staple. Unfortunately, that hasn’t convinced most companies to lower their prices. At Target, you’ll get three pounds for $12 (not bad), but Costco offers 4.5 pounds for $9. It’s still not as cheap as rice, but it’s definitely a healthier option.

Extra Virgin Olive Oil

A 2010 report found that most EVOO on U.S. store shelves wasn’t extra virgin like their labels claimed. One notable exception: Kirkland’s organic version. So not only are you paying less per serving than you would at the supermarket, but you can guarantee good quality. How’s that for a solid deal?

(Getty)

Cheese

If you think everything tastes better when covered in cheese, Costco is the place to be. From goat cheese and Brie to Parmesan and Pecorino Romano, its cheeses are cheesemonger-quality with warehouse prices. The value-sized hunks of cheese might be excessive for a dinner for two, but Kirkland should be your go-to if you’re planning a party. Just steer clear of these things you should never buy at Costco.

(Getty)

Baby formula

When you have an infant in tow, the last thing you want to worry about is overpriced baby formula. The FDA has strict nutrition requirements for baby formula, and Costco’s version is no exception. The non-GMO Kirkland baby formula’s ingredient list is nearly identical to Similac Advance’s, but it costs about half as much per ounce. Make sure you know these 15 secrets Costco employees won’t tell you.

Is it safe to eat?

Apeel is perfectly edible. The U.S. Food and Drug Administration says it is fully compliant with their regulations and safe to eat. Though the peel can’t be washed off, it’s completely colorless, odorless, and tasteless—so you wouldn’t notice it after biting into an apple.

If you are to eat Apeel, the natural fats wouldn’t make much difference in your overall diet. Apeel Sciences states that if your diet consisted only of fruits and vegetables with Apeel, your daily caloric intake of fat coming from Apeel would be less than one calorie a day.

What is Apeel Sciences?

Apeel Sciences is fighting the war on food waste one peel at a time. Their plant-based peel is made with natural elements, instead of chemicals and preservatives, making their practices sustainable. According to their website, Apeel’s vision is for “a world where we work with nature—rather than against it—to create solutions to the world’s greatest challenges.” Their mission is to “help fresh food providers improve quality, reduce waste and ensure an abundant future for our planet.”

Apeel has products that are OMRI Listed for the growers and distributors of USDA Certified Organic produce. With this approval, they hope to provide their peel to more produce products in an effort to reduce the $2.6 trillion dollar food waste problem that the Food and Agriculture Organization deals with worldwide.

Does all of Costco’s produce have this magical peel?

At the moment, Apeel Sciences only offers Apeel for avocados at major U.S. grocery stores. Costco is one of them. However, the company does hope to make it available for dozens of other fruits and vegetables.

So if you’re the type of shopper who buys in bulk, grabbing avocados at Costco may not be a bad idea!
