Is a baked muffin colloid?

A colloid is a mixture in which one substance (the dispersed phase) is distributed throughout another substance (the continuous phase). The dispersed phase is typically a solid, liquid, or gas, while the continuous phase is typically a liquid or gas. The particles in a colloid are larger than those in a solution but smaller than those in a suspension.

A baked muffin is a colloid because it contains a dispersed phase of solid particles (such as flour, sugar, and baking powder) distributed throughout a continuous phase of liquid (such as water, milk, and eggs). The solid particles in a baked muffin are typically between 1 and 1000 nanometers in size.

Baked muffins are examples of solid foams, which are colloids in which the dispersed phase is a gas and the continuous phase is a solid. Other examples of solid foams include bread, cake, and marshmallows.
