Understanding Snack Food Production

The Process of Food Extrusion

The food extrusion process uses high-temperature and high-pressure conditions to push ingredients through a special barrel which produces consistent processed food products. The process consists of multiple steps which must be completed in order to achieve the necessary quality standards for the final product. The main components of the process consist of ingredient preparation, preconditioning, extrusion, and post-processing.

The blending process begins with raw ingredients which include grains and starches and proteins to create a uniform mixture containing specific moisture and temperature characteristics. The preconditioning stage begins with the heating of the mixture to create a partially cooked state which will enable it to be fed into the extrusion machine. The process requires steam or water to be injected into the material for the purpose of achieving specific texture and consistency results.

The extrusion process forces the material to pass through a die which produces the intended shape while the material undergoes immediate cooking through high-temperature and high-pressure vaporization. The product experiences molecular structural changes due to the combination of heat and shear forces which create improvements in both digestibility and texture. Post-processing involves the steps of cutting and drying and flavoring the extruded products. The standardized procedure produces snacks which include cereals and crackers and puffing products through an efficient process that generates extremely low waste.
