enriched

Enriched is the past participle of enrich, and is used to describe something enhanced by adding nutrients, information, experience, or other valuable components. In nutrition, products labeled enriched have had nutrients added to replace those lost during processing, such as enriched bread or refined grains fortified with iron and B vitamins. In the food industry, enrichment is distinct from fortification in that the added nutrients are ones that are naturally present in the original product but removed or reduced in processing.

In nuclear science, enriched uranium refers to uranium whose concentration of the fissile isotope U-235 has been increased from its natural level. Low-enriched uranium is used as fuel in most civilian reactors; highly enriched uranium has a higher share of U-235 and is subject to international safeguards due to proliferation concerns. Enrichment is achieved by isotope separation methods such as gas centrifugation or gaseous diffusion, conducted under strict control and verification.

In psychology and animal welfare, an enriched environment is a setting that provides increased sensory, cognitive, and social stimuli to promote development, learning, and neuroplasticity. In education and science, enrichment can also refer to enrichment cultures or enriched growth media that supply extra nutrients to support the growth of particular microorganisms.

The term also appears in general usage to mean that a dataset, user interface, or experience has been made more informative or valuable by adding context or features.
