Do Sweet Potatoes Oxidize & How Can I Prevent It?

Hey, friends!

Do you know that this sweet potato oxidizes?

But we have a few tricks up our sleeves that can help prevent oxidation.

Let’s talk about them below.

Do raw sweet potatoes oxidize?

To answer this question, you need to know a bit about the oxidation process.

When naturally occurring plant molecules called phenols come into contact with air, they react and combine to form compounds known as melanoidins.

This reaction can occur when foods are cut or bruised, for example—or it can happen in fresh produce like sweet potatoes that have been stored in the refrigerator for too long.

The length of time required for sweet potatoes to oxidize depends on several factors: how long they’ve been stored after harvesting; whether they’ve been stored whole or peeled; how tightly they’re wrapped; whether they’re refrigerated or left at room temperature; and how much air exposure is allowed during storage (e.g., unwrapped versus wrapped).

Why do sweet potatoes oxidize?

The reason is because they contain beta-carotene, which is a fat-soluble vitamin that can be damaged by heat and light.

Beta-carotene is the orange pigment in sweet potatoes that gives them their bright hue.

It’s also found in other colorful fruits and vegetables like carrots, mangoes and cantaloupe.

If you’re wondering why we don’t just eat these foods raw, it’s because we need some heat to break down the beta-carotene so that our bodies can absorb it.

When you cook a sweet potato (or any vegetable rich in beta-carotene), you’re essentially unlocking all of its health benefits for maximum enjoyment!

Sweet potatoes oxidize very quickly.

In fact, they can turn brown in as little as two hours if left out in the open air.

If you want to prevent your sweet potatoes from oxidizing, store them in the refrigerator or a cool place (about 50 degrees Fahrenheit).

If you’re planning on eating your sweet potatoes within a few days and don’t want to mess with wrapping them individually in plastic wrap (which is easy but not always practical), consider keeping them whole instead of cutting them up into pieces first.

This will allow you to use them before they get too soft!

If you’re using sweet potatoes in a recipe, be sure to cut them into smaller pieces.

That way, if they do oxidize, the piece will be small enough that it won’t affect the overall flavor of your dish.

If you are using them as part of a dish where they will be cooked (like roasted or baked), then you can leave them whole and use them without cutting them up first.

If you choose to eat oxidized sweet potatoes on their own, slice open one end of the bulbous part of your sweet potato and scoop out everything inside into a bowl so that no extra parts remain attached to the skin.

Then throw away everything else—including any peels or eyes—and slice up what’s left over into thin sticks for snacking on top of salads or burgers!

To keep sweet potatoes fresh, you should:

  • Keep them in the fridge.
  • This is the most effective way to prevent oxidation and keep your sweet potatoes from turning brown.
  • If you have no more room in your refrigerator, try wrapping each one individually in foil or placing them into a resealable plastic bag before storing them in the crisper drawer of your fridge.
  • Freeze them instead of refrigerating them if you don’t have any more room for fresh ones!
  • When thawed, they’ll retain most of their nutrients and flavor, unlike refrigerated ones which risk spoiling before they can be eaten up by time.

The answer is that you can do pretty much anything.

But there are certain things that will help keep your sweet potatoes from oxidizing, so consider these options.

  • Fridge: Keeping your sweet potatoes in the fridge is an easy way to prevent them from oxidizing, as it slows down both their growth and their activity.
  • They’ll eventually need to be taken out of the fridge and stored at room temperature, but you can easily store them there until they’re ready to be used.
  • Foil or plastic bag: You can also keep your sweet potato wrapped in foil or placed inside a plastic bag if you have some extra space in the fridge and want to be extra safe about preventing oxidation!
  • This method might take up more room in your refrigerator than simply storing them on their own, though—so this might not be ideal if space is limited!

Conclusion

There you have it!

There’s a lot to go over here but don’t worry.

As long as you follow my instructions you’ll be okay.

Overall, I would say that yes sweet potatoes (like most vegetables) will oxidize when exposed to heat but the effects are negligible.

Just make certain that you’ve taken the steps discussed above and you’ll be golden!
