lämpöherkkien

Lämpöherkkien is a Finnish term used to describe items, substances, or systems that are sensitive to heat. Grammatically, lämpöherkkien is the genitive plural form of the adjective lämpöherkkä, used when referring to “of heat-sensitive [things].” In scientific and technical usage, the concept covers any material or entity whose structure or function degrades, changes, or becomes inactive at elevated temperatures.

In biology and biochemistry, proteins, enzymes, and nucleic acids are often heat-sensitive; denaturation and loss of activity occur when exposed to high temperatures. In medicine and pharmaceuticals, many drugs and vaccines are thermolabile and require storage and handling under controlled temperatures. In materials science and electronics, polymers, adhesives, and certain electronic components can soften, oxidize, or suffer performance degradation with heat. The term is also used in food science to describe nutrients, flavors, or textures that degrade when heated.

To manage heat sensitivity, researchers and industry rely on temperature-controlled storage (cold chain), rapid cooling, stabilization additives, and packaging that minimizes temperature fluctuations. Analytical methods such as differential scanning calorimetry and thermogravimetric analysis help assess the thermal stability of heat-sensitive materials and formulations. Understanding heat sensitivity informs quality control, transport, and formulation across fields.
