Science seeks to answer the great questions of the human being, but it can also deal with other more everyday ones such as the best way to eat a cream-filled chocolate biscuit, for which rheology seems to hold the key.
A new study published by Physics of Fluids analyzes how to rotate the two sides of a cream-filled cookie sandwich, in this case Oreos, so that they don’t break, and even establishes why the filling is always on one side, which, in addition, , is not always the same.
Rheology is the part of physics that studies the physical principles that regulate the movement of fluids or, in other words, the one that studies the relationship between stress and deformation of materials that are capable of flowing.
The study conducted by a team from the Massachusetts Institute of Technology (MIT) characterized the flow and fracture of the cookies and found that the cream, whose rheological texture is officially “soft”, tends to stick to one side of the cookie.
The study confirms what many consumers verify empirically, that is, that when the two biscuits are separated, the cream remains in only one.
The team put the cookies in a rheometer to measure the torque needed to pull them apart and how the cream would distribute. The main author, Crystal Owens, considered that if they were rotated perfectly, the filling would be distributed between both surfaces, but “almost always” it is all on one side.
The explanation may lie in the way the cookies are made or how they are oriented during packaging, since those in the same box “used to follow the same trend and varied from one box to another, possibly due to different storage conditions.” ”, he indicated.
There are many ways to eat this type of cookie, you can even find tutorials on the internet, and the most famous would be to turn them in opposite directions so that the cream remains in one of them and eat them separately.
The best way to cleanly separate the cookies depends, according to the study, on the speed of rotation. If they are turned quickly, “it will take more effort and more stress to separate them,” Owens said, so he recommends doing it “a little more slowly.” (I)
