Abstract: The present invention relates to a method for producing a composition for use as a vaccine for treatment or prevention of cancer. The method includes the steps of isolating dendritic cells from a blood, bone marrow or other tissue sample of a patient suffering from cancer or from an unrelated donor, culturing the dendritic cells under conditions and pulsing the dendritic cells with tumour cell lysate or an antigen released by the type of tumour cell and a tocotrienol.

Abstract: A process for preparing palm-based polyol monomer includes reacting unsaturated fatty acids or its corresponding triglycerides with polyhydric alcohol. In particular, one example uses oleic acid with about 70% purity as the starting material for preparing the polyol monomer. Moreover, another example uses refined, bleached, and deodorized (RBD) palm olein as an alternative to oleic acid as the starting material. The preparation of the polyol monomer involves the production of monoglyceride of unsaturated fatty acids, which was further epoxidized with peracid and finally ring opened with polyhydric alcohols. Such polyol monomer is used as a raw material for the production of various types of polyurethane products.

Abstract: Phytosterols, squalene and Vitamin E are recovered from phytonutrients concentrate derived from crude palm oil by the disclosed invention via esterification, transesterification, vacuum distillation, saponification, crystallization and organic solvents partitioning. Crude palm oil is subjected to esterification and transesterification for the production of crude palm oil methyl esters. Phytonutrients concentrate containing phytosterols, squalene, Vitamin E and unreacted monoglycerides is recovered from crude palm oil methyl esters by multi-stages vacuum distillation in which components with higher molecular weight are filtered during second stage vacuum distillation. The purified phytonutrients concentrate is subjected to saponification process and the unsaponifiable matter is added to a combination of solvents for crystallization of phytosterols. The filtrate enriched in squalene and Vitamin E is separated to its individual squalene-rich layer and vitamin E-rich layer via organic solvents partitioning.

Abstract: The present invention relates to a process for producing high purity monoglycerides from edible oils/fats and fatty acids through glycerolysis, in particular but not exclusively to the production of monoglycerides from palm oil and palm oil products. This is achieved by providing a process for the production of monoglycerides of fatty acids or fats and oils, comprising the steps of reacting fatty acids or fats and oils with excess glycerol in the presence of an acidic or alkaline catalyst; substantially separating the crude reaction product from the other reaction components; removing unwanted reaction components from the crude reaction product by washing; drying the reaction product.

Abstract: 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° C., wherein DAG oil is obtained as distillate and whereas TAG oil is obtained as residue.

Abstract: A process for the separation and recovery of minor components from vegetable oil such as palm oil. Esterified palm oil is subjected to molecular distillation giving a concentrate rich in minor components. The concentrate is then adsorbed to adsorbents such as normal phase silica gel, reversed phase (particularly C18) silica gel or neutral alumina as well as polymer absorbents such as polyethylene glycol and polyacrylate polyalcohol. Minor components such as squalene, carotenes, tocols and sterols are then selectively desorbed, separated and recovered using solvents operating at isocratic conditions. The desorption of the said minor components are sped up by applying pressure of between 0.2 to 50 bar. By the same method, individual tocols isomers from palm oil can also be separated and recovered.
