The invention relates to vegetable oil products, including palm oil products, containing one or more constituents from a group which includes monoacylglycerols, diacylglycerols, triacylglycerols, carotenes, tocols, phytosterols, squalene and free fatty acids, from vegetable oil sources and a process for the production thereof by using supercritical fluid extraction.

Specialty palm oil products and other specialty vegetable oil products

The present invention relates to a method for production of two types of edible oils, an oil type with high diacylglycerol content (DAG oil) containing at least 8 wt % diacylglycerol and another oil type with low diacylglycerol content (TAG oil) containing less than 8 wt % diacylglycerol, from a vegetable oil. The method comprises subjecting a vegetable oil to at least one stage of short-path distillation under vacuum level of not more than 0.01 Torr and at temperature of not more than 300&#xb0; C., wherein DAG oil is obtained as distillate and whereas TAG oil is obtained as residue.

Production of edible oil

A process for the recovery of phytonutrients such as carotenes, phospholipids and ubiquinones from palm oil esters is disclosed. This process comprises the steps of vacuum distillation, treatment and purification of concentrate containing these phytonutrients. The alkyl esters is subjected to at least one stage vacuum distillation at temperature from 80&#xb0; C. to 220&#xb0; C. and pressure less than 40 mTorr. The carotenes concentrate is subjected to various physical and chemical treatments to yield higher carotenes concentration enriched with ubiquinones in indigenous diacylglycerols.
