Steam Distillation

Steam distillation is the most common way to extract aromatic compounds (essential oil) from a plant. During the steam distillation process, steam passes through the plant material. The combination of heated steam and gentle pressure causes the essential oil to be released from microscopic protective sacs. As the vapor mixture flows through a condenser and cools, it yields a layer of oil and a layer of water. The essential oil rises to the top and is separated from the hydrosol (floral water) and collected.


The temperature for steam distilling is usually between 140–212 degrees Fahrenheit. Since different plants require different pressures, times, and temperatures, using this particular distillation method makes it possible to adjust the temperature based on the plant type, making it a very effective and precise way to obtain the purest compounds.



Cold Pressed

Unlike steam distillation, cold pressed, does not involve heat. In this process, oil is extracted from the product under mechanical pressure. We uses expression to extract all of its citrus oils, such as Wild Orange, Lemon, Lime, Bergamot, and Grapefruit, from the rind.


Proper distillation requires a consideration for the uniqueness of pressure, temperature, time, and harvesting practices, each of which may be as diverse as the plants themselves. A poor distillation process can alter or destroy the necessary aromatic compounds that comprise the essential oil, leaving a substance far different from the intended goal and something that would not be used to support health and wellness. For this reason, the best distillation artisans dedicate their efforts and work to only a few select plants. This focused effort develops proper knowledge and experience, helping ensure congruency between the oil chemistry of the plant and its distilled form.

Steam Distillation

Steam Distillation (penyulingan uap) adalah cara yang paling umum untuk mengekstrak senyawa aromatik (essential oil) dari tanaman. Selama proses penyulingan uap, uap melewati bahan tanaman. Kombinasi uap panas dan tekanan lembut menyebabka essential oil dilepaskan dari kantung pelindung mikroskopik. Saat campuran uap mengalir melalui kondensor dan mendingin, ia menghasilkan lapisan minyak dan lapisan air. Essential oil naik ke atas dan dipisahkan dari hidrosol (air bunga) dan dikumpulkan.


Suhu untuk penyulingan uap biasanya antara 140-212 derajat Fahrenheit. Karena tanaman yang berbeda memerlukan tekanan, waktu, dan suhu yang berbeda, dengan menggunakan metode distilasi khusus ini memungkinkan untuk menyesuaikan suhu berdasarkan jenis tanaman, menjadikannya cara yang sangat efektif dan tepat untuk mendapatkan senyawa paling murni.



Cold Pressed

Tidak seperti distilasi uap, cold pressed, tidak melibatkan panas. Dalam proses ini, minyak diekstrak dari produk dibawah tekanan mekanis. Kami menggunakan ekspresi untuk mengekstrak semua minyak sitrusnya, seperti Wild Orange, Lemon, Lime, Bergamot, dan Grapefruit, dari kulitnya.


Penyulingan yang tepat memerlukan pertimbangan untuk keunikan tekanan, suhu, waktu, dan praktik pemanenan, yang masing-masing dapat beragam seperti tanaman itu sendiri. Proses destilasi yang buruk dapat mengubah atau menghancurkan senyawa aromatik yang diperlukan yang terdiri dari minyak esensial, meninggalkan zat yang jauh berbeda dari tujuan yang diinginkan dan sesuatu yang tidak akan digunakan untuk mendukung kesehatan dan kesehatan. Untuk alasan ini, perajin penyulingan terbaik mendedikasikan usaha mereka dan hanya bekerja pada beberapa tanaman pilihan. Usaha yang terfokus ini mengembangkan pengetahuan dan pengalaman yang tepat, membantu memastikan kesesuaian antara bahan kimia minyak tanaman dan bentuk distilasinya.
