When you cut a sweet potato, you are exposing the flesh to air.

Oxygen will react with the natural sugars in the sweet potato, causing it to turn brown.

Sweet potatoes also turn brown when exposed to light or heat.

The darker color of cooked sweet potato is due to its increased exposure to oxygen and light over time as well as its longer cooking time at higher temperatures.

Sweet potatoes contain more natural sugars than regular potatoes do; this may be why they discolor faster after cutting than white-fleshed ones do.

Sweet potatoes will keep for up to five days in the refrigerator if stored properly.

To store sweet potatoes correctly, place them in a plastic bag, then wrap that bag with another plastic bag so that no air gets inside (the air will cause browning).

If you have any extra room in your fridge, you could even put a plate under the bowl or container that holds your sweet potatoes so they don’t touch anything else and get damaged by other foods’ juices.

You can also freeze pre-cut sweet potatoes for up to one year at a time!

The easiest way is to wash and peel your sweet potato(es), then cut them into cubes before placing them on a parchment paper-lined baking sheet or silicone mat as individual pieces.
