Luonnonöljyt
Luonnonöljyt, or natural oils, refer to lipid substances derived from plants and animals. These oils are primarily composed of triglycerides, which are esters of glycerol and fatty acids. Their properties vary significantly depending on the type of fatty acids present. Plant-based natural oils are extracted from seeds, fruits, or nuts through methods like pressing or solvent extraction. Common examples include olive oil, sunflower oil, and coconut oil, each possessing distinct fatty acid profiles and applications in food, cosmetics, and industry. Animal-based natural oils, such as fish oil and lanolin, are obtained from animal tissues and also have diverse uses, including nutritional supplements and skincare. The chemical structure of fatty acids, particularly the presence and configuration of double bonds, determines the oil's physical state (liquid or solid at room temperature) and its susceptibility to oxidation. Natural oils are a vital part of human diet, providing essential fatty acids and contributing to energy intake. They also play a significant role in various industrial processes, including the production of soaps, biofuels, and lubricants. The sourcing and sustainability of natural oils are increasingly important considerations due to environmental and ethical concerns.
