kioldás

Kioldás is a Hungarian noun meaning the act of releasing, disengaging, or removing something that is held or bound. It is used in several domains, and its precise sense depends on context. In everyday language it can refer to the release of a mechanism, such as triggering a safety device or opening a lock by releasing a component.

In chemistry and chemical engineering kioldás denotes extraction or leaching—the process of removing a substance from a solid matrix or mixture by contacting it with a solvent. This can occur as solid-liquid extraction, where a solid material releases soluble constituents into a liquid, or as liquid-liquid extraction, where a solute partitions between two immiscible liquids. The efficiency of kioldás depends on solvent choice, temperature, time, and system design.

In pharmacognosy, food science, and natural products chemistry kioldás describes the isolation of active compounds, flavors, or essential oils from plant or microbial material. The resulting extract can be used for further analysis, formulation, or processing.

In mechanical and industrial contexts kioldás can also mean the release or disengagement of a device or mechanism, such as releasing a spring, valve, or lock, enabling subsequent operation or safety functions.

Overall, kioldás conveys the general idea of moving something from a held or bound state to a released state, whether through chemical, mechanical, or process-driven means.
