What's Up With Those Green Potato Chips You Sometimes Find?

??Well, they're not dyed for St. Patrick’s Day. These are just from potatoes in which chlorophyll had started to form. This can happen when potatoes, which grow underground, are exposed to too much light in the field or factory, in storage, on the store shelf, or in your home.

The USDA’s “Standards for Grades of Potatoes” consider a potato that’s more than 5 percent green to be damaged, and potato lots that contain them will be graded below US Grade #1. That means most green potatoes never even make it to market.

You’ll still see some every now and again, either in whole or chip form, if conditions in the potato chip plant, the grocery store, or your kitchen are right. Fluorescent lighting and a room temperature of at least 68°F can get the greening process going in a raw potato in just three to five days, and some varieties of potato will start turning in as little as 12 hours even under low incandescent lighting.

By itself, chlorophyll is nothing to be worried about; it’s tasteless and nontoxic. In the process of a potato going green, though, conditions are also right for it to synthesize more of a glycoalkaloid (alkaloid + sugar) poison called solanine, which potato plants produce in their leaves, stems, sprouts and flesh as a defense against insects and other predators. Ingesting solanine can cause nausea, diarrhea, vomiting, stomach cramps, burning sensations in the throat, dysrhythmia, headaches, fever, hallucinations, jaundice, paralysis and death. Toxic levels for people are around one one-hundredth of an ounce for a 200-pound person, who would have to eat about 20 pounds of normal whole potatoes in one day to get sick. With very green potatoes, where the solanine level can increase ten-fold, only two pounds of spuds could leave you ill.

As for potato chips, solanine formation is localized near the potato's skin, usually no deeper than 3 mm. As they're peeled for processing, most of the flesh making up those three millimeters is typically removed. Whatever flecks of green are left are not going to be enough to do anything to you. So, go ahead - finish the whole bag if you want.

What About Dark Brown Potato Chips?

A different matter altogether. Brown potato chips are the result of potatoes being stored too long at low temperatures and accumulating excess sugar. When a potato chip is baked or fried, the sugar reacts with amino acids to produce that beautiful golden-brown color, but too much sugar leads to a very dark brown, almost burnt-looking, color and a slightly different, off flavor.

When the hit Star Wars series The Mandalorian premiered on Disney+ last fall, executives withheld merchandise to make sure viewers were surprised by the sudden appearance of The Child, a cooing puppet that appears to be of the same species as Jedi master Yoda. Knowing demand for toys and other items for "Baby Yoda" would be high, Disney stood firm.

Those days are over. Now, fans of the series can buy everything from The Child plush dolls to the space macarons the goblin-faced tyke munches on in the fourth episode of the show’s second season. The blue macarons, dubbed Nevarro Nummies after the name of the planet Mando and The Child landed on in the episode, are available at Williams Sonoma for $49.99.

According to the company’s site, the “ethereal French-style almond macarons” are perfect for “capturing the essence of this scene.” Bear in mind the “essence” of the scene involves The Child throwing a Force tantrum by using his skills to swipe the cookies from a student’s desk while briefly placed at a school.

The precocious creature’s voracious appetite has been a running theme on the series, with some viewers taken aback by a scene in an earlier episode in which he devoured the eggs of a critically endangered frog species. (“Baby Yoda Canceled Amid Accusations of Genocide,” read the Vanity Fair headline.) What will Baby Yoda eat next, and can you buy it? Tune in this week to find out.
