Naphthas are used for extraction on a fairly wide scale. They are applied in extracting residual oil from castor beans, soybeans, cottonseed, and wheat germ and in the recovery of grease from mixed garbage and refuse. The solvent employed in these cases is a hexane cut, boiling from about 65 to 120°C (150 to 250°F). When the oils recovered are of edible grade or... 

Most TAG mixtures show little optical activity, but castor oil and those unusual oils containing acylglycerols of cyclopentene acids (e.g., chaulmoogric and hydno-carpic acids present in the seed oils of Flacourticeae) are notable exceptions. Samples containing sterols will display some optical activity dne to the presence of these optically active compounds. Becanse most edible oils have low optical activity, a method has been proposed to detect the adnlteration of edible oils with castor oil based on the optical activity of ricinoleic acid (1,2-dihydroxyoctadecenoic acid), a major constitnent of castor oil (Babn et al., 1996). 

Castor oil is classed as an industrial oil because it is used only for nonfood purposes (Section 5.1). Linseed oil also is used almost entirely for industrial purposes. In its limited use as an edible oil, it is generally known by its alternative name of flaxseed oil (Section 5.7). 

Unmodified castor oil is not used in edible products apart from its limited medicinal use. It is mainly used... 

In most commercially important edible plant oils, the dominant fatty acids are oleic, linoleic and linolenic acids. Coconut oil is an exception in having the saturated 12 0 lauric acid as its major acid. Families of plants tend to produce characteristic oils that frequently contain unusual fatty acids. Examples are the erucic acid of rape-seed ricinoleic acid, the 18-carbon, monoenoic, hydroxy acid of the castor bean and vernolic acid, the 18-carbon, trienoic, epoxy acid of the Compositae. 

Ricinoleic acid is the main acid of castor bean oil, comprising up to 90% of the total acids. Hence, it can serve as an indicator for the presence of this oil in edible oil blends. 

Oils and fats are also used for non-food purposes, such as the production of motor fuels, in oleochemistry and cosmetics. For these purposes, common edible oils and fats of lower quality are used. Some oils are obtained specifically for technological purposes, such as castor oil or tung oil. A typical example of the use of oils as fuel for diesel engines is the production of fatty acid methyl esters, especially from rapeseed oil. Oleochemicals from oils and fats manufacturing include fatty acids, fatty alcohols and other derivatives for the production of surfactants and subsequently detergents, paints, plastics, adhesives, building materials and many other products.
