Does cutting sweet potatoes with non stainless steel knives cause oxidation poisoning? - A Person Cutting a Flattened Raw Clay Pot

I have found when cutting up sweet potatoes prior to cooking that the cut edges go grey or black when soaked in warm water. I read on another site that using a carbon or non stainless steel knife causes oxidization. So my question is, if this be true, is it a health hazard?



Best Answer

Oxidation is not a health hazard, no matter how you spell it. Your sweet potatoes are as healthy kind of brown as they ever were.

What is the best knife to cut sweet potatoes?

Because sweet potatoes are dense, you'll want a knife that is big enough and sharp enough to make a smooth cut, like a 7-5/8" Petite Chef knife. After peeling the potato, find a place on it where it can rest on the cutting board without too much roll or wobble.

Do sweet potatoes oxidize?

It's safe to say that sweet potatoes might not keep as well as regular potatoes, and there's a reason for that. Sweet potatoes are jam-packed with oxidizing enzymes that are highly reactive. What is this? However, there are many ways you can prevent them from oxidizing and turning brown.

What are the cons of stainless steel knives?

The disadvantage of stainless steel knives is that they are usually not as sharp as carbon knives. They also have a lower cutting durability due to their lower hardness. Because of the carbides found in stainless steel, these knives cannot be sharpened as easily.

What are the pros and cons of stainless steel knives?

Stainless or surgical steel knives are low cost and their high chromium content makes them impervious to rust and stains. However, their flimsiness makes them hard to sharpen, and they do not maintain their edge because sharpening destroys the soft steel instead of creating a fine cutting edge.
