Cood In the food processing industry, the colloid is the one that thickens food, provides adhesion and gel-forming ability, and helps to obtain the desired shape, viscosity, hardness, thickness, crispness and softness of food. For example, the natural colloid can act as a thickener in some soups and sauces. It can also perform gel-forming ability in pudding and jelly, or emulsify in yogurt, ice cream, etc.

Stability: The colloidal properties are stable. The particles in the dispersed phase move continuously and remain suspended in the solution.

Homogeneous appearance: Although colloids have suspended particles and are heterogeneous in nature, they appear to be homogeneous solutions. This is because the suspended particles are very small and invisible to the naked eye.

Colloids have great applications in the food industry. Many of the food materials we eat are colloidal in nature. Milk and many dairy products, such as cheese and butter, are all colloids.

In chemistry, a colloid is a phase separated mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance.

Combining different substances can result in five main types of colloid mixtures: aerosols, foams, emulsions, sols and gels.

A colloid must be heterogeneous, i.e., consist of dissimilar constituents, for example, silver and water. It must be multiphasic, i.e., solid/liquid, gas/liquid, etc. The particles must be insoluble in the solution or suspension.

In fact, most common edible colloids are natural. Some are carbohydrates and proteins, others are derived from microbial fermentation.
