10‐hydroxy decanoic acid, trans‐10‐hydroxy‐2‐decanoic acid, and sebacic acid: Source, metabolism, and potential health functionalities and nutraceutical applications

Abstract The popularity of royal jelly (RJ) as a functional food has attracted attention from various industries, especially nutraceuticals, due to the increasing demand from health enthusiasts. Sebacic acid, 10‐hydroxy decanoic acid, and trans‐10‐hydroxy‐2‐decanoic acid are the primary medium‐chain fatty acids (MCFAs) within RJ responsible for their health benefits. This review aims to consolidate information on these MCFAs’ metabolic relationship and health functionalities in nutraceutical applications. We also investigated the natural characteristics mediated by these MCFAs and their metabolism in organisms. Finally, the production of these MCFAs using conventional (from castor oil) and alternative (from RJ) pathways was also discussed. This review can be a reference for using them as functional ingredients in nutraceutical industries.
