Hereof, what kind of fluid is ketchup?

Ketchup is a shear thinning fluid. Shear thinning means that the fluid viscosity decreases with increasing shear stress.

Beside above, does ketchup contain water? Ketchup is a mixture that most importantly includes tomatoes, but also includes water to give it its texture. After sitting still for a while, the tomatoes and the water separate, and the water rises to the top of the bottle. You can shake the bottle to mix them again, but they will never mix permanently.

In this manner, is ketchup liquid or solid?

But tomato sauce prefers to be in the bottle because it is technically a solid, not a liquid.” Like toothpaste and paint, ketchup is a “soft solid” or “yield stress fluid” that only moves when the right amount of force is applied. The sauce is actually a suspension of pulverized tomato solids in a liquid.

Is ketchup a Pseudoplastic?

Ketchup is known as a Casson plastic, meaning it has a non-linear flow once the critical stress point is overcome. That's why you have to hit the bottle hard to get the ketchup to flow. This force overcomes the stress point and allows the ketchup to flow very quickly.
