Stretchable Gel

Hi Guys,

I'm working (mostly thought experimenting) on a recipe. I need a gel which I can stretch and it can keep it's new shape once stretched... I've tried some but generally I get brittle gels with Agar, Gelatin, Gellan Gum (Low Acyl) etc...

So a simple use case is sth. like this. Let's say I've made a ribbon of length 15 cm, and when applied some force (and probably some heat as well) I can stretch it to 30 cm... Etc... And I can keep stretching further.

I think I might need a long polymer hydro-colloid or some modified starches but not sure where to start with. Any guidance is highly appreciated.

I guess I'm defining a hydro-colloid (or a blend), which is partially thermo-reversible or thermo-relaxed (just coined) so that I can further shape it without melting after it's set.

Application would be helpful. Immediately I think of an ultratex 8 or similar but it depends on what you are trying to stretch and why and will you want it to "set" once stretched.

Hi Todd,

I don't want it set once stretched.

I want to stretch and set multiple times. Think of an application like traditional Noodles.

Don't the starches gel and set for traditional noodles as well? Though i guess its off topic

Well, they have a starchy taste.. And I think you also rely on gluten for that elasticity too?
