Jaboties and oils are lipidnye materials, got from plants. Physically, oils are liquid at a room temperature; fats - hard. Chemically - as fats and oils consist of trigliceridov, unlike a beeswax which does not have glycerin in his structure. Although many parts of plant can serve as raw material for oils - in commercial practice of butter obtained mainly from seed. Jaboties and oils are divided by edible and uneatable. Examples are uneatable jaboties and oils: processed linseed oil, tung oil, castor oil (used in lubricating materials, paints, Cosmetology, pharmaceutics and other industrial aims). Many vegetable oils are consumed in food straight or indirectly, as ingredients in food stuffs - they replace adiposes, including desi and melted butter.
Mainly setting of oils it giving viscidity, teksturirovanie, giving and withholding of aromas in cookery. oils can be heated and to serve for preparation in their environment of other products. For this purpose oils must have a high temperature of igniting. The best of all the soy-bean befit for this purpose, rape, sunflower, peanut, cotton oils and other tropical oils such as a palm-oil, coconut butter and butter of rice brans, from their unusually high temperature of igniting is especially valued in the Asiatic cultures, where the high temperature of preparation of food is used.
The unsaturated fats of vegetable and oils can be regenerate by the partial or complete hydrogenizing in fats and oils with more high temperature of melting. The process of hydrogenizing plugs in itself "splashing" of butter at a high temperature and pressure in an environment with hydrogen in presence a catalyst (as a rule - powdery connection of nickel). Butter can be hydrogenated for the increase of stability to progorkaniyu (to oxidization) or on purpose change his physical descriptions. When the degree of satiation is increased - viscidity of butter and his temperature of melting is increased also.
Vegetable oils are used as an ingredient or component in many kinds by the produced industry of products. Many vegetable oils are used for a production washed, candles, products on the care of skin, perfumes, other cosmetic facilities and facilities of the personal hygiene.
Some oils especially well befit for preservation and used for making of oily paints and other products of treatment of wood.
Butter Dammar (mixture of linseed oil and resin is a dammar) for example, used almost exceptionally for renewal of corps of wooden courts.
Vegetable oils are all more frequent used in electrical engineering industry as insulators, because vegetable oils are not toxic for an environment.
oils which are more stable, for example, ben-oils, are preferable to some industrial aims. Vegetable oils on the basis of, for example, castor oil, used as medicine and as greasing in the flow of great while. Castor oil has a great number of applications in industrial aims, above all things from the presence of hydroxy-groups on the chain of fat acids. Castor oil and other vegetable oils which were chemically modified, to contain hydroxy-groups, acquire all greater value in the production of poliuretanovogo plastic.
Vegetable butter is used in the production of some forage. AAFCO determines vegetable butter, in this context, as a product of phytogenous, got by extraction of butter from seed or garden-stuffs which are processed for food aims.
Vegetable oils also used for making of biodiesel which can be used as an ordinary fuel-oil.
