摘要：

Selenium-enriched peptide (SP) is a new type of selenium supplement with unique bioactivities; however, its instability jeopardizes its industrial applications. Hence, a system stabilizing and delivering SP is a prerequisite to overcome this defect. This study developed a microcapsule, dextran-whey protein isolate-selenium-enriched peptide (DX-WPI-SP), encapsulating SP within the WPI-DX glycation product via electrospraying technology, and its properties were characterized. Results showed that DX-WPI-SP considerably surpassed the physical mixture of WPI, DX, and SP, with respect to antioxidant capacity, thermal stability, and cell cytotoxicity. The in vitro gastrointestinal digestion results showed that over 42% of the SP in DX-WPI-SP survived the gastric fluids and was then released in the intestinal phase. The stability of SP in long-term storage was also observed after its encapsulation in DX-WPI-SP, signifying its stability in this delivery system. This study demonstrated that the DX-WPI-SP microcapsule is a valid strategy to stabilize SP in intestinal delivery.
