Soluble fibers can be fermentable but not gel-forming, gel-forming but poorly fermentable, or possess both or neither property.

“important to be aware that these two properties uh, viscosity and fermentability are not mutually exclusive. You'll notice that because I just use pectin as an example in both. So, some soluble fibers are fermentable but don't form gels. Others are gel forming forming but poorly fermentable. And some can do both and some may do neither.”
