TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The enzyme is selected from Candida antarctica, Candida rugosa, Rhizomucor miehei, Pseudomonas species, Rhizopus niveus, Mucor javanicus, Rhizopus oryzae, Aspergillus niger, Penicillium camernbertii, Alcaligenes species, Burkholderia species, Thermomyces lanuginosa, Chromobacterium viscosum, papaya seeds and pancreatin. In the method (M3), the plant oil is soybean, canola, rapeseed, olive, palm oil, sunflower oil, peanut oil, cotton seed oil, waste cooking oil or any oil triglycerides derived from inedible plant sources.    TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Components: The enzyme is a lipase or a phospholipase. The interfacial enzyme immobilized on a solid porous support is homogenously covered with a surfactant (preferably with a monolayer of the surfactant). Preferred Method: In the method (M1), prior to mixing with the enzyme biphasic solution obtained in second step, the support is optionally washed to remove salts and organic materials, and is then treated with a surfactant dissolved in a second organic solvent.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The insoluble support is capable of binding the enzyme by adsorption or by covalent binding to functional groups. The support is a porous support which may be organic or inorganic (preferably selected from porous inorganic support such as silica- or alumina-based supports, organic supports such as polymer-based support, where the support may optionally contain active functional groups such as epoxy or aldehyde groups, or ionic groups).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The first organic solvent is selected from alkanes (such as octane), alcohols (such as n-octanol), aldehydes (such as decanaldehyde) and/or ketones (such as 2-octanone). The surfactant is selected from sugar fatty acid esters, polyoxyethylene sugar fatty acid esters or ethers, medium- and long-chain alkyl glucosides, phospholipids, polyethylene glycol derivatives and quaternary ammonium salts. The second organic solvent is selected from alkanes such as n-hexane, ethers such as diethyl ether, ketones such as acetone, and/or alcohols such as isopropanol. In the method (M2), the alcohol is 2-22C alkanol (preferably cetyl alcohol).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The support is an ion exchange resin. EXAMPLE - Lipozyme TL (RTM: immobilized lipase) was prepared as follows: Enzyme support (1 g) was first washed with water to remove any adsorbed salts and organic residues. The support was filtered off and then dried under vacuum to remove water residues. The dried support (1 g) was mixed with organic solvent such as n-hexane or isopropanol containing a non-ionic, anionic or cationic surfactant (100 mg). The organic solvent was evaporated under vacuum to yield a dried support covered homogenously with a surfactant (which was e.g. phosphatidyl choline, AOT (sodium bis-(2- ethylhexyl) sulphosuccinate)). Lipase derived from Thermomyces lanuginosa (1 ml of Lipozyme TL 100 l) was mixed in a biphase system comprised of phosphate buffer (10 ml) of 0.05 M and pH 6.5, and n-hexane. The mixture was vigorously stirred for 10 minutes followed by the addition of the surfactant-treated porous support. The mixture was stirred for an additional 4 hours. The support containing the immobilized enzyme was filtered off and dried in a desiccator overnight to yield the highly active immobilized lipase. The relative transesterification activity of Lipozyme TL 100 l immobilized on Amberlite XAD 4 (RTM: support) was carried out as follows: Reactions were carried out by adding immobilized lipase (0.5 g) to olive oil (10 g) and cetyl alcohol (5.5 g) (The molar ratio oil triglycerides:cetyl alcohol was 2:1). The reaction system was mixed magnetically or by shaking at 60 degrees C. The conversion of olive oil triglycerides to wax esters was determined after three hours of reaction by calculating the ratio of the sum of the peaks area of olive oil triglycerides after 3 hours of reaction and sum of peaks area of olive oil triglycerides at time zero. The conversion (%) of olive oil triglycerides to wax esters after 3 hours of reaction on support Amberlite XAD 4 of 67%. When the reaction reaches steady-state conditions, the immobilized enzyme was filtered off to obtain the desired product. The product was comprised of wax esters and monoglycerides inherent to olive oil at a molar ratio of 2:1, respectively. This unique ratio grants the product improved water dispersibility and was used for the preparation of cream emulsions with no need for use of external emulsifiers.
