Extracting Plant Essence ¨C
Collecting the Treasure between Heaven and Earth
Plant essential oils are stored in the oil sacs of plants;
oil sacs of different plants are clustered at different
locations, some in the flowers, and some in the fruits.
Each essential oil is different in the property, some
of which cannot be heated, and some are easy to
lose fragrance. In order to achieve the best collection
effect, essential oils will be extracted in different ways
Nut and Seed Oils
Squeezing Method: generally used to extract essential oils
from citrus, nuts and kernels. Just as what the name implies,
it uses centrifuge or cold press to squeeze the essential oils
from peels and kernels.
Fresh, Steam-distilled Essential Oils
Distillation Method: the most traditional extraction method with
the most extensive use. Plants are distilled for the essential
oils by the heated steam in the distiller, which are cooled and
collected. When they become liquid, the moisture and
essential
oils in them are separated.
Solvent Extraction Method: Raw materials are placed into the
lipolysin or volatile
solvent for soaking to make them release
waxes and essential oils which are
extracted with medicinal
alcohol. The essential oils are also referred to as plant
absolutes
which are generally used to extract delicate fragrance from
precious
flowers.
Pure Plant Hydrosols
The liquid extracted from plants with distillation method will separate
into essential
oils and water.During the separation, some essential
oils are still residual in water.
Plus the water-soluble ingredients in
the plants, these constitute hydrosols (also
referred to as hydrolats)
extensively used as senior skin care products. Along with
essential oils,
wonderful complement effect can be achieved. |
