Finally, starch gelatinization occurs, a chemical process that governs textural changes, so one's well-prepared spaghetti is al dente. As this happens, the spaghetti swells, and small amounts of a starch called amylose leach into the water. So what happens to the dried spaghetti when it is submerged in boiling water? Only a few seconds are needed for the strands to reach the same temperature as the water, but it takes a bit longer for water to work its way through the starch matrix of the pasta.

The commercial products are then dried-another active area of research, since it's easy for the strands to crack during the process. Then it sinks slowly to the bottom of the pot, where it will curl back on itself to form a U shape.Īs we reported at the time, spaghetti, like most pasta, is made of semolina flour, which is mixed with water to form a paste and then extruded to create a desired shape (in this case, a thin, straight rod).

The twist weakens the snap-back effect, and as the strand twists back and unwinds to its original straightness, it will release pent-up energy in the strand so there aren't any additional breaks.īack in 2020, physicists at the University of California, Berkeley, provided a thorough explanation for why a strand of spaghetti in a pot of boiling water will start to sag as it softens. In 2018, Ars reported on work by two MIT mathematicians who figured out a useful trick: twist the spaghetti at 270 degrees before slowly bringing the two ends together to snap the spaghetti in two. But where's the fun in that?)Ī paper on their findings has just been accepted for publication in the journal Physics of Fluids, and two of the authors presented the work at this week's meeting of the American Physical Society in Chicago. (And yes, horrified Italians, the tasting method works just fine too. Among other findings, the UIUC physicists came up with a simple technique, using just a ruler, to determine when one's spaghetti is perfectly al dente, with no need for the time-honored tradition of throwing a cooked strand against the wall-although the latter arguably requires less setup. That's how physicists from the University of Illinois at Urbana-Champaign (UIUC) found themselves casting about for experiments that could be done at home in the kitchen. The physicists ended up investigating the physics of cooking pasta-first conducting home experiments, then repeating those with greater precision in the lab once the university reopened.Ĭooking instructions on most packaged dried pastas typically recommend an 8 to 10 minute cooking time, but it's an imprecise method that can result in a great deal of variation in the consistency of the cooked pasta. Scientists found themselves working from home along with most everyone else when universities shut down in the face of the COVID-19 pandemic-including laboratories, posing a unique challenge for experimentalists in particular.
