Construction and in vitro digestibility evaluation of a novel human milk fat substitute rich in structured triglycerides

The infants who cannot be breastfeed need to obtain energy and nutrition from other sources, such as formula. In this study, a human milk fat substitute (HMFS) rich in structured triglycerides (STG) with variety of fatty acids was prepared by one-step transesterification reaction. optimum conditions for the lipase-catalyzed between basa catfish oil solid fraction, Cinnamomum camphora seed kernel oil, linseed microbial algae were studied vitro digestibility constructed HMFS investigated. Under optimal conditions, obtained contained 58.86% STG 39.73% sn-2 palmitic acid (PA). Fatty composition analysis showed that composed capric (Ca), lauric (La), oleic (O), linoleic (L), linolenic (Ln), arachidonic (ARA) docosahexaenoic (DHA). LC-MS/MS found 142 new generated, Ca-P-ARA, Ca-P-Ln, La-P-ARA, La-P-L P-O-ARA. Moreover, compared physical mixture (PM), had better melting crystallization temperature release rate significantly improved. These results suggested may have great application infant food nutritional ingredient.
