That juice is high-fructose corn syrup, a sugarglop that's killing both the American people and the American tradition of agriculture. 

HFCS, as it's called, is a relentlessly common sweetener in everything from soft drink to bread. It's used because, in bulk, it's incredibly cheap, thanks to agricultural subsidies from the US government that encourage farmers to grow the high-yield, flavorless-when-unprocessed variety of corn used for HFCS. One of the many odd things about high-fructose corn syrup is that you can't really buy the pure stuff in a store. What's even in the stuff? That's what artist and designer Maya Weinstein wondered - except she actually secured the ingredients for her thesis project at Parsons.

The DIY HFCS Kit includes all of the delicious materials that go into the US's finest weirdest sweetener: glucose isomerase, sulfuric acid, alpha amylase, and more (those enzymes are used to convert the glucose to fructose). It's not that hard to make: basically, just combine everything in the kit besides the glucose isomerase, strain through cheesecloth, heat, add glucose isomerase, boil, and cool.

Weinstein went over to the Bon Appetit offices to demonstrate her kit, and, interestingly, it was a hit with the editors there. Before it's filtered to remove its yellow color and much of its flavor, it "tastes like corn candy," according to the editor of Bon Appetit's site. The filtering removes any extant flavors that might not go with whatever you want to sweeten, and in mass production, this syrup is often purified to become as high as 90% fructose - nearly pure sweetness, basically.

The project isn't really for mass consumption; the kit itself costs $70-80 in raw materials to yield just a small jar of corn syrup. Corn syrup is used by so many food producers because it's cheap in bulk, and because the government gives lots of rebates and tax incentives to use the stuff - in small doses, it's cheaper to go with honey or plain sugar. But it's a pretty interesting experiment to see how something Americans eat all the time is actually made. Check out the project here.
