New research from Lund University reveals that gluten plays a vital role in keeping spaghetti intact while boiling What prevents spaghetti from falling apart when cooked in boiling water? According to recent research, gluten is the key factor. The quantity of salt added to the cooking water also plays a surprisingly important role.
To investigate, scientists used advanced analytical methods to examine the internal structure of store-bought spaghetti in both regular and gluten-free forms. Their results indicate that gluten is essential for maintaining the pasta’s structure while it cooks.
“We were able to show that the gluten in regular spaghetti acts as a safety net that preserves the starch. The gluten-free pasta, which contains an artificial matrix, only works optimally under exactly the right cooking conditions – otherwise the structure easily falls apart,” says Andrea Scotti, senior lecturer in physical chemistry at Lund University.
Scotti used both small-angle neutron scattering and X-rays in the research. These methods make it possible to study foods at the microscopic level – down to a billionth of a meter – and link these findings to product characteristics such as texture, shelf life, and glycaemic index.
The new study also concludes that the salt in the pasta water plays a role in the end result.
The Role of Salt in Pasta Perfection
“Our results show that regular pasta has higher tolerance, or better structural resistance, to less optimal cooking conditions such as being cooked for too long or too much salt being added to the water. So, cooking pasta with the right amount of salt is not just a matter of taste – it also affects the microstructure of the pasta and thus the whole dining experience,” says Andrea Scotti.
The researchers now plan to continue their work by studying more types of pasta and different manufacturing conditions, as well as replicating what happens to the pasta once it is in the stomach, to see what effect digestion has on its chemical structure.
“With demand for gluten-free alternatives increasing, we hope that our methods can help develop more durable and nutritious products that stand up to the demands placed on them by both the cooking process and by consumers,” says Andrea Scotti.

The research was conducted together with Judith Houston, lead instrument scientist for the LoKI instrument at the European Spallation Source (ESS) in Lund, Sweden, and collaborators from the Institut Laue-Langevin in France and the Diamond Light Source and ISIS Neutron and Muon Source in the UK.
Italian Scientists ? The ones dumping spaghetti in the US ?
They just pasta buck............
Is linguini better? Sounds sexier.
Always add salt to the pasta water; NEVER add oil!
I add garlic while boiling potatoes before mashing them.
I only trust the spaghetti research of Professor Al Dente.
Unfortunately he was eaten by the Flying Spaghetti Monster................
Dunno, Professore Boyardi is pretty sharp.
I heard he ran off with Angel Harris.
I heard it wasn’t the FSM, it was a group from the Pastafarian Cult.
They need to investigate the attempt to corner the pasta market by crime boss Alfredo Fettuccine.
“Professore Boyardi is pretty sharp.”
Yeah, but he overcooks his pasta and his sauce is just awful.
What did the gluten-free spaghetti say when it started crumbling in the pot? “I guess I just don’t have the ‘net’ to hold it together!” Unlike its gluten-packed cousin, it needs perfect cooking conditions to avoid a total noodle disaster.
The 11th Commandment.
If my Italian grandmother saw anyone ruin pasta water by putting oil in it she would have crippled them with her big wooden spoon!
My wife makes the best linguini in white clam sauce you ever had. It is my favorite pasta dish. She is Italian, her grandfather was off the boat. But she got the recipe from a magazine, made it once, then modified it to her taste. She is an incredible chef.
How much did American taxpayers pay to fund this useless study? Because you KNOW we did.
It’s Swedish.....................
It’s Swedish.....................
Angel Hair — sounds almost pornographic...
