What Are The Brown Spots On Your Potato Chips? (2024)

What are the brown spots on potato chips? ›

Wilson said the dark spots on the chips are unrelated to ring rot and are common for potatoes used for chips. Discoloration in potato chips is cosmetic and they are still safe to eat. "(They) are dark spots or dark coloring from bruising, changes in sugars during storage or vascular discoloration," he said.

The cold temperatures needed for long-term storage of potatoes cause the starch in spuds to break down into smaller sugar molecules. It's the reaction between these sugars and the extreme heat of deep frying that causes browning.

Unlike the common belief that a back or brown spot on your potato chips is a sign of spoilage, experts say that they are actually either bruises or the result of excess potato sugars darkening during frying. This also means that such potatoes are still safe for consumption despite bearing such minor imperfections.

There is an insect called the Tomato/Potato psyllid that can cause 'Zebra Chip' which causes brown flecking throughout the potato. If it was psyllid, you wouldn't have had a good crop, so it is unlikely to be insect damage, but more caused by environmental stress.

Bruising during the frying process: Many experts suggest that the black and brown dots on potato chips, including Pringles, are actually bruises that occur during the frying process. These bruises can turn black due to the excess sugars present in the chips [1].

Soreen potato chips, while a bit off-putting, are totally safe to eat. Much like green potatoes, a few spots of green are unlikely to cause serious side effects. Eat 'em or trash 'em, it's your choice! (Learn more about whether you can eat sprouted potatoes.)

Different types of snacks have varying expiration dates: Potato chips will last one month after expiration date. Crackers and pretzels can last up to three months. One of the longest lasting snacks is popcorn, which has a shelf life of one to two years. " / There is a myth that Twinkies can last upward of 50 years.

This process, which is called oxidation, happens because potatoes are a naturally starchy vegetable. And when exposed to oxygen, starches turn gray, brown, or even black. An oxidized potato is completely safe to eat. The process doesn't affect the flavor or texture of the vegetable.

browning, are dependent on the degree of acidity present during frying. Studies revealed that the initial presence of reducing sugars was not a re- quirement for the browning reaction, provided sucrose was present and con- ditions were favourable foiits hydroiysis. seem to be in the promotion of sucrose hydrolysis.

The moldy looking spots are a condition that can develop from the bruises, called fusarium. The potatoes are still safe to eat, just cut the spots away. If there is an extensive amount of fusarium, this can give the potatoes an “off” flavor.

These spots are called internal black spot and are essentially bruising that occurs from the potatoes lying against each other for an extended period of time. The moldy looking spots are a more serious condition that can develop from the bruises, called fusarium.

The USDA says that you don't need to discard green potatoes, but you should prepare them properly: “Peel the skins, shoots, and any green color; that is where the solanines concentrate.” Be a little aggressive if the flesh is still green beneath the peel and remove all traces of it.

If the green tint on your taters is light and mostly skin-deep, peel them well to remove the green parts and go forth. But if they're starting to look like post-transformation Fiona, it's time to pitch 'em. Same goes for potatoes that have gone mushy or wrinkly—those are tell-tale signs of spoilage.

Brown spot and Black pit are fungal diseases of potato caused by the fungus Alternaria alternata. On leaves, it causes relatively small dark brown spots of necrotic tissue with a dark brown margin. Starting as small lesions, the spots can coalesce to cover a large percentage of leaf or petiole surface.

The disease can cause wilting of the potato plant but the symptoms you are most likely to see is in the tubers. The initial symptom is brown staining of the vascular ring (hence the name "brown" rot) which later rots completely. A grey-white ooze may exude from the eyes and heel end of the potato.

Bacteria need oxygen to thrive, and if all of the oxygen is removed, it can't grow. This means there is no chance of mold, mildew, or other substances showing up on the chips. It keeps away moisture. In addition to oxygen, moisture is an enemy of potato chips.

The white, raised spots on your potatoes are probably swollen lenticels due to wet soil conditions. Potato tubers are enlarged underground stems. Lenticels are small openings in the tuber surface that allow for gas exchange. Saturated soils may cause the lenticels to swell as gas exchange is impeded.
