This chapter evaluates the potential solutions to the several drawbacks reported in the literature and known by the authors due to their research activity related to laboratory testing of lipases in ST and SD synthesis. These solutions are analyzed in terms of their advantages and disadvantages and with the economical aspects properly considered.
Nowadays ,the issue of trans fatty acids is very important. These fatty acids are generated during hydrogenation by isomerization and industry is required to explore different processes other than hydrogenation of fats. Interesterification as an alternative to hydrogenation is suitable for health-concerned customers, and random or chemical interesterification is the most used process. It is less complicated and expensive and is easier than enzymatic interesterification.
ST and SD synthesis has been prepared using chemical interesterification. However, the potential solution to the high cost involved in enzymatic reactions could be addressed if non-expensive local new enzymes are obtained (using recombination or exploring new sources of lipases such as local plants). In addition, the use of cheaper substrates and other reaction routes would add a potential improvement in cost (such as glycerol). The innovation of the use of multiphasic reactors could add an important solution to the need for the reuse of immobilization.
