Many food-processing operations are designed to create the microstructure that gives the food product its characteristic properties. From milk we can produce different cheeses, yogurts, spreads, or whipped products where the properties are determined by the structure. Other examples of fabricated foods are cereal products such as pasta, meat products such as sausages, and so on. All of these products are based on colloidal structures such as gels, emulsions, foams, or combinations thereof. Microscopy provides the tools for describing how a particular structure is engineered, and, therefore, how it relates to the properties of the product.
