TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Components: The at least one lipolytic enzyme is chosen from lipase, cutinase, phospholipase (A1, A2, B, C, and D), acyltransferase or their combinations. The at least one immobilized lipolytic enzyme is immobilized on carrier either by adsorption or entrapment. The liquid preparation comprising at least one lipolytic enzyme further comprises water, glycerol, and/or liquid reactant. The reactant feedstock is chosen from babassu oil, borage oil, canola oil, coconut oil, corn oil, cotton oil, hemp oil, Jatropha oil, karanja oil, mustard oil, palm oil, peanut oil, rapeseed oil, rice oil, soybean oil, sunflower oil, oil from microalgae, animal fat, tallow, lard, butterfat, poultry fat, marine oils, tuna oil, hoki liver oil, fatty acid distillates, acid oils, waste oil, used cooking oil, partial glycerides and their combinations. Preferred Method: The method involves performing process chosen from alcoholysis, esterification, interesterification, transesterification, condensation and glycerolysis. The method is performed in batch reactor, continuous stirred tank reactor, packed bed reactor, moving packed bed reactor, and expanded bed reactor.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The carrier is a hydrophilic carrier chosen from porous inorganic particles and porous organic particles. The porous inorganic particles are chosen from alumina, silica and silicates, porous glass, zeolite, diatomaceous earth, bentonite, vermiculite, and hydrotalcite. The porous organic particles are chosen from carbohydrate polymers preferably agarose or cellulose, or polymers, preferably polypropylene, polyethylene, and acrylate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The reactant feedstock comprises at least one fatty acid ester and alcohol. The alcohol is methanol or ethanol. The reactant feedstock comprises a first fatty acid ester and a second fatty acid ester. The reactant feedstock comprises triglycerides, diglycerides, monoglycerides, free fatty acids, or their combinations. The fatty acid ester product comprises fatty acid alkyl esters, preferably methyl-, ethyl-, propyl-, isopropyl-, or butyl-esters. EXAMPLE - No suitable example given.
