There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
The oil is also very rich in natural antioxidants, such as tocopherols, making this highly stable oil very resistant to oxidation and rancidity. [12] It has 1–3% erucic acid ; recently, several low-erucic and zero-erucic Camelina sativa varieties (with erucic acid content of less than 1%) have been introduced. [ 12 ]
As a way to reduce fossil fuel emissions, the US Navy tested a 50-50 mix of jet aviation fuel and biofuel derived from camelina seeds in 2010. [1] A study published in December 2016 explained that the current low price of conventional kerosene-based jet fuel makes it cost-prohibitive for commercial airlines to use camelina-based jet fuel. The ...
The essential oil of this plant, which contains the chemical compound geraniol, is valued for its scent and for traditional medicinal and household uses. Palmarosa oil may be an effective insect repellent when applied to stored grain and beans, [5] an antihelmintic against nematodes, [6] and an antifungal and mosquito repellent. [7]
The name ylang-ylang is the Spanish spelling of the Tagalog term for the tree, ilang-ilang - a reduplicative form of the word ilang, meaning "wilderness", alluding to the tree's natural habitat. [7] A common mistranslation is "flower of flowers". [6] The tree is also called the fragrant cananga, Macassar-oil plant, or perfume tree.
Rapeseed oil is predominantly cultivated in its winter form in most of Europe and Asia due to the requirement of vernalization to start the process of flowering. It is sown in autumn and remains in a leaf rosette on the soil surface during the winter. The plant grows a long vertical stem in the next spring followed by lateral branch development.
Patchouli (also spelled patchouly or pachouli) (/ p ə ˈ tʃ uː l i /; Pogostemon cablin) is a species of flowering plant in the family Lamiaceae, commonly called the mint or deadnettle family. The plant grows as a bushy perennial herb , with erect stems reaching up to 75 centimetres (30 in) in height and bearing small, pale, pink-white flowers.
The flower is a vital ingredient in Kewra and is used in special-occasion dishes in South Asia, particularly those associated with Muslim communities. [2] Kewra flowers have a sweet, perfumed odour with a pleasant quality similar to rose flowers, but kewra is more fruity. The aqueous distillate (kewra water, pandanus flower water) is quite diluted.
