Abstract

PURPOSE:To obtain fats and oils for frying with hardly any rise in acid value and deterioration in color tone and flavor due to excellent heating stability by treating a medium-melting fraction prepared by fractionating refined palm oil with an alkali. CONSTITUTION:Crude palm oil is subjected to suitable combination of degumming, deacidifying, bleaching, deodorizing treatment, etc., to remove gums, substances adsorbed on clay, free fatty acids, etc., and afford refined palm oil, which is then subjected to natural fractionation, fractionation with a surfactant or solvent, etc., to provide a medium-melting fraction having 29-46 iodine value. An aqueous solution of an alkali, such as caustic soda, in especially preferably 3-16wt.% concentration in an amount of especially preferably 2-3wt.% is subsequently added, mixed and stirred to carry out alkali treatment. Bleaching and deodorizing with steam are then carried out to afford refined palm oil.

[Prior Art and Problems to be Solved by the Invention] Palm oil has a lower content of unsaturated acids higher than dienoic acids in the constituent fatty acids of triglycerides than other vegetable oils, such as soybean oil, rapeseed oil, and cottonseed oil. Taking advantage of its characteristics, it has been reported that palm oil can be used as a fat for frying, which requires heat stability.

It is thought that higher heat stability can be imparted by further reducing the content of unsaturated acids higher than dienoic acid, and the medium melting point fraction of palm oil is triglyceride mainly composed of di-palmitolein. Therefore, in theory, it is possible to easily obtain the desired oil for frying by separating the medium melting point fraction.

However, although the mid-melting point fraction of palm oil is composed of triglycerides composed of highly stable fatty acids, it also contains trace components in the raw palm oil and trace amounts of modified components due to damage sustained during the manufacturing process. Since conventional refining methods do not remove these trace components, it has not been possible to obtain frying fats and oils with good heat stability from the medium-melting point fraction of palm oil.
