At present, there are 4 main extraction technology for wheat germ oil processing: supercritical CO2 fluid extraction, traditional solvent extraction, low temperature pressing and subcritical low temperature extraction. But the some of these methods have a lot of shortcomings.
Supercritical CO2 fluid extraction High Cost, Low Output: As its requirements for equipment is very high, supercritical CO2 fluid extraction machine is very expensive. Besides, its output is low and difficult to adapt to large-scale production.
Traditional Solvent Extraction (Hexane) High processing temperature, high energy consumption, low quality of oilcakes or meals. It is a process of extracting oil at normal pressure by use of Hexane. The temperature of extracting process and desolventizing process is high, resulting in high rate of protein degeneration of oilcakes or meals.
Low Temperature Oil Pressing - High residual oil content in oil cakes / meals; high impurities and moisture content. Direct squeezing or expelling is not suitable for low oil yield materials such as wheat germ.
Advantages of Subcritical Extraction Technology
Subcritical Extraction Technology is a kind of pressurized (0.3-0.8 MPa) fluid extraction process. The extracting agent exists in the form of gas under normal pressure, while under critical pressure it exists in the fluid state. Under critical pressure, the molecular diffusion ability of extraction solvent is enhanced, transfer rate is accelerated, permeability and dissolving capacity is improved significantly. Besides, as it is a kind of low temperature extraction technology, the natural active ingredient in extraction materials are fully retained and protected.
The extraction process is cut off from the air, which can avoided oxidation reaction of special materials and help getting high grade oil products just as supercritical extraction. But the extraction pressure is much lower than supercritical extraction, which is a good thing that makes the equipment price is much lower and also make it feasible for industrialization scale production.
It's been found to contain vitamins A and B, as well as plant-based lipids and fatty acids. Wheat germ oil is made from the same nutrients that we humans need to thrive

The high quality bulgarian rose oil gained its producers scores of medals and diplomas from many exhibitions and fairs. The rose valley in bulgaria, near the town of kazanlak, is among the major producers of attar of roses in the world.

Lemon balm essential oil (also known as Melissa essential oil) has a great variety of possible effects.

Rose oils are extracted from the Rosa damascena (Bulgarian) and Rosa centifolia (Moroccan) also known as 'rose de mai'. Rose Otto is the essential oil steam distilled from fresh roses. Rose concrete a solvent extraction of fresh roses. Rose absolute is extracted from the rose concrete using alcohol. Rose Otto is distilled from the Bulgarian rose or Rosa damscena. The Otto is an almost clear pale yellow liquid. When it is very cold it solidifies but it is easily warmed to liquid again. Rose Otto smells rich, floral, warm and spicy with honey undertones. The smell of fresh roses becomes more apparent at when the Otto is diluted. Rose Otto is the most expensive extract of roses.

The health benefits of Lavandin Essential Oil can be attributed to its properties as an antidepressant, antiseptic, analgesic, cicatrisant, expectorant, nervine, and vulnerary substance. The Lavandin, plant from which this essential oil is obtained, is not a natural plant in the true sense because it was born as a result of the hybridization of two plants with the scientific names Lavandula Angustifolia and Lavandula Latifolia. That is why Lavandin is scientifically known as Lavandula Hybrida and Lavandula Hortensis. The aroma and medicinal properties of Lavandin are quite similar to those of Lavender, but they are more intense and sharp since it is a hybrid. The main components of this oil are Lavandulol, Linalool, Linalyl Acetate, Camphor, Cineole, Caryophyllene, Camphene, Dipentene, Limonene, Ocimene, and Terpinene. Lavandin oil boosts self-esteem, confidence, hope, and mental strength, while efficiently fighting depression. This can be very helpful to drive away depression for those who are suffering from depression due to a failure in their career or personal relationships, insecurity, loneliness, stagnation, someoneâ??s death, or for any other reason. This also relieves anxiety. As an antidepressant, it can be systematically administered to patients with acute depression who are undergoing rehabilitation
