The word commonly is used to describe puréed vegetable or seed and nut products such as peanut butter and almond butter. In general use, the term "butter" refers to the spread dairy product when unqualified by other descriptors. The latinized form is found in the name butyric acid, a compound found in rancid butter and dairy products such as Parmesan cheese. The word turos ("cheese") is attested in Mycenaean Greek. This may be a compound of βοῦς ( bous), "ox, cow" + τυρός ( turos), "cheese", that is "cow-cheese". The word butter derives (via Germanic languages) from the Latin butyrum, which is the latinisation of the Greek βούτυρον ( bouturon). Its natural, unmodified color is dependent on the source animal's feed and genetics, but the commercial manufacturing process commonly manipulates the color with food colorings like annatto or carotene. It generally has a pale yellow color, but varies from deep yellow to nearly white. The density of butter is 911 grams per litre (0.950 lb per US pint). Butter remains a firm solid when refrigerated, but softens to a spreadable consistency at room temperature, and melts to a thin liquid consistency at 32 to 35 ☌ (90 to 95 ☏). Rendering butter, removing the water and milk solids, produces clarified butter or ghee, which is almost entirely butterfat.īutter is a water-in-oil emulsion resulting from an inversion of the cream, where the milk proteins are the emulsifiers.
Salt and food colorings are sometimes added to butter. It is made by churning milk or cream to separate the fat globules from the buttermilk. Most frequently made from cow's milk, butter can also be manufactured from the milk of other mammals, including sheep, goats, buffalo, and yaks. It is used at room temperature as a spread, melted as a condiment, and used as an ingredient in baking, sauce making, pan frying, and other cooking procedures. It is a semi-solid emulsion at room temperature, consisting of approximately 80% butterfat.
Butter is a dairy product made from the fat and protein components of churned cream.
