• Primitive mills and presses for extraction of oils from seeds have been in use sevice long. Mechanization came with the introduction of the hydraulic press by the end of the 18th Century. This too was replaced by the more efficient screw press or expeller towards the end of the last century.
• The first chemical process applied to fats and oils (excluding oxidation in burning) was saponification for making soap. Industrialization of oils and fats began with the installation of a cotton seed oil mill in South California in about 1826.
• The methods were crude and the product was impure in 1850 the use of caustic soda to remove free acids from the oil was introduced in France. About this time the millers became aware of the value of linters (fibre) that clung to the Hulls, and also of the Hulls themselves as cattle feed.
• By 1887, more scientific methods of refining were introduced. In 1983 it was learned that the oil could be deodorized by blowing steam through it at high temperatures. In 1900 the discovery that oils could be hydrogenated to produce fats of different consistencies revolutionised the entire oil and fat industry. So far no comprehensive and absolute classification of vegetable fats and oils is made though various schemes have been used based on origin, physical characteristics, composition or use, or combinations of these factors.
• They are more commonly classified according to their capacity for absorbing iodine i.e. Iodine value. Those with a high proportion of double bonds are called drying oils, those intermediate in capacity are called semidrying and those of low capacity non-drying. In general the non-drying and semi-drying oils are used as foods and as lubricants and the drying oils as paint and varnish ingredients. This distinction has never been a very precise one and is becoming less so as oils formerly classified as semi-drying such as soyabean are being used more and more in paints varnishes and other products that dry in a highly satisfactory way.
