椰子油

化学的特性Coconut oil generally occurs as a white to light-yellow mass or colorless or light-yellow clear oil, with a slight odor characteristic of coconut and a mild taste. Refined coconut oil is a white or almost white unctuous mass. The form that coconut oil takes depends on temperature; it occurs as a pale yellow to colorless liquid between 288℃ and 308℃, as a semisolid at 208℃ , and as a hard brittle crystalline solid below 158℃.

解説ヤシ科（APG分類：ヤシ科）のココヤシの果実の核から得られる脂肪。核の含油部分を乾燥したものをコプラcopraという。このコプラから圧搾法により採油される。コプラ油とも称する。コプラの品質は乾燥に左右され、水分が多いものはカビを生じ、油が酸敗するから、水分を8％以下にする必要がある。コプラの乾燥度は、やし油の品質、収量に影響を及ぼす。コプラの形で東南アジアなど熱帯原産地から輸出される。含油量65～75％。マーガリン、カカオ脂代用品（水素添加やし油）、せっけん、高級アルコール、脂肪酸、グリセリン原料として用いられる。なお、パーム核油はやし油にきわめて類似した成分を有している。［福住一雄 2019年5月21日］[参照項目] | パーム核油 小学館 日本大百科全書(ニッポニカ) ）

It is stable when exposed to air. Coconut oil may be irritating to the skin and cause skin rashes. It is also considered comedogenic.

一般的な説明Coconut oil is extracted from the dried pulp of coconuts and usually contains around 63% to 70% oil. It is usually semi-solid when kept at room temperature, with a white or light-yellow to orange appearance and a distinct coconut aroma. The main components of coconut oil are glycerides of lauric acid, myristic acid, and oleic acid. Its melting point ranges from 23 to 28 degrees Celsius, and its relative density falls between 0.917 to 0.919 at 25/25°C. Coconut oil has a saponification value ranging from 250 to 264, with an iodine value of 8 to 12 and an acid value that does not exceed 6. It is soluble in alcohol, chloroform, ether, and carbon disulfide, but insoluble in water. When exposed to air, it is prone to rancidity. Coconut oil can be saponified at room temperature with a caustic soda solution. It has many uses, including the production of soap, edible fat, chocolate, candy, and many others.

Coconut oil is the fixed oil obtained from the seeds of Cocos nucifera Linn. (Palmae). This oil is then refined to produce refined coconut oil, which is referred to in the coconut industry as RBD (refined, bleached, and deodorized) coconut oil.
