Essential Oils: Distillation & Expression

Essential oils are produced in the cells of aromatic plants and are held in specialized glands. They are released from the plant and collected (concentrated) most often through steam distillation (and sometimes hydro or water distillation or a combination thereof). Distillation is a method of separating components based on differences in volatile constituents in a heated mixture. Steam distillation involves bubbling steam through the plant material. The temperature of steam is easy to control, making it ideal for heat-sensitive essential oils. The essential oils contained in plants are immiscible in water and have a higher boiling point, allowing the essential oil to vaporize at a lower temperature than it normally would on its own. Other methods used to create pure essential oils are dry or vacuum distillation, dry/destructive distillation, and expression (for citrus peels). Expression, also referred to as "cold pressed", is a method where oil is obtained by using high mechanical pressure to literally squeeze the oil from the plant material.

 

 

 

 


精油在芳香植物的细胞中产生,并被保存在专门的腺体中。它们从植物中释放并最经常通过蒸汽蒸馏(有时为水或水蒸馏或其组合)收集(浓缩)。蒸馏是一种基于加热混合物中挥发性成分差异分离组分的方法。蒸汽蒸馏涉及通过植物材料冒泡蒸汽。蒸汽的温度很容易控制,因此非常适用于热敏感的精油。植物中含有的精油在水中不混溶,并具有较高的沸点,使精油在比通常情况下更低的温度下蒸发。用于制造纯精油的其他方法是干式或真空式蒸馏,干式/破坏性蒸馏和表达(用于柑橘皮)。表达,也被称为冷压,是通过使用高机械压力从植物材料中逐字挤压油获得油的方法。
