| Summary: | 碩士 === 國立勤益科技大學 === 化工與材料工程系 === 100 === This study attempts to find the appropriate method for extracting non-water soluble bioactive molecules from papaya and intends to use the natural materials: oil bodies, isolated from the sesame seeds, to encapsulate the alcohol-extracted and the ester-extracted antioxidant substances from the papaya into microspheres. The non-water soluble bioactive molecules were incorporated into these microspheres with an encapsulation efficiency up to 55% and 85% respectively, depending on the loading ratios.
The antioxidant capacities assays include α,α-diphenyl-β-picrylhydrazyl(DPPH) radical scavenging activity measurement, and 2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging activity measurement , ferrous ion chelating power measurement. Our current results show that the treatment of encapsulation by oil bodies could be beneficial for long-term preservation of poorly-soluble biomolecules and could increase the bioavailability.
