This short provides the state-of-the-art on enzymatic synthesis of dependent triglycerides and diglycerides, targeting glycerol because the substrate and protecting interesterification of vegetable oils in a single and steps. It severely experiences the to be had literature on enzymatic and chemo-enzymatic synthesis of di- and triglycerides in a single or extra steps. the consequences of the constitution, size and unsaturation of the fatty acids are rigorously thought of, in addition to the inhibitory strength of hugely unsaturated complicated fatty acid structures.
The short additionally addresses acyl migration and using adsorbents, bearing in mind the newest literature and providing the matter in an business context. It discusses experimental and analytical difficulties bearing on, e.g. the lab scale and the scaling as much as bench and pilot vegetation. a number of examples are offered, and their successes and screw ups are assessed. Biocatalysts in keeping with lipases are analyzed in regards to difficulties of immobilization, balance on garage time and task after a number of makes use of. the necessity for particular Sn-2 lipases is gifted and methods for optimizing Sn-2 esterification are mentioned. finally, useful features are tested, e.g. lipase “leaching” with lack of task, bearing in mind the newest findings on non-stop and batch reactor configurations and providing the benefits and downsides of each.
