homogenize

Homogenize (verb) means to make the components of a mixture uniform in composition or properties throughout. In practice it often means mixing or dispersing substances so that no region remains with a different concentration or phase.

Etymology: from the Greek homo- meaning same and -genēs meaning born or produced; homogenization denotes a process that makes a substance of uniform kind throughout. The noun forms are homogenization or homogenisation depending on spelling.

In dairy processing, milk homogenization uses high pressure to break fat globules into smaller particles, distributing fat evenly and preventing creaming. The process enhances texture and stability, and it is usually followed by pasteurization, though it is distinct from heat treatment.

In chemistry and food science, homogenization refers to creating a uniform mixture of immiscible liquids or finely dispersed solids, often with emulsifiers and mechanical devices such as homogenizers, mills, or high-shear mixers. It can also describe standardizing a sample or material across batches to reduce variability.

In mathematics, homogenization converts a non-homogeneous polynomial or expression into a homogeneous one by introducing an auxiliary variable, producing terms of the same total degree. For example, a non-homogeneous polynomial f(x, y) = x^2 + y becomes F(x, y, t) = x^2 + y t, where t is the new variable, ensuring all terms have the same degree.

In data processing and standards contexts, homogenization refers to methods that align data from different sources to common scales or reference frames, enabling meaningful comparison or aggregation across datasets. See also homogenized mixtures and projective homogenization.
