Olajat

Olajat is the Hungarian accusative form of olaj, meaning oil. As a general term, it covers viscous liquids derived from plants, animals, or minerals that are used in cooking, lubrication, lighting, and industry. Oils can be thin or thick and may vary widely in aroma, flavor, and chemical composition.

Edible oils include olive, sunflower, canola, soybean, palm, coconut, and others. They are produced by pressing seeds or fruits and, if needed, refined to remove impurities, improve color, or stabilize flavor. Nutritionally, oils are concentrated sources of fats and calories; their health effects depend on fatty acid composition, with monounsaturated and polyunsaturated fats generally favored over saturated fats. The smoke point of an oil influences its suitability for different cooking methods.

Industrial oils encompass mineral oils and synthetic oils used as lubricants, coolants, and hydraulic fluids in machinery. Essential oils are volatile aromatic compounds extracted from plants by distillation or expression; they are valued for flavor, fragrance, and therapeutic uses, but are chemically distinct from fat-based edible oils.

Storage and safety practices emphasize keeping oils in cool, dark, tightly sealed containers to minimize oxidation and rancidity. Some oils are stable at room temperature, while others require refrigeration. Sustainability considerations apply to production, notably the environmental and social impacts of palm and other crop oils.
