Arachidonic acid (AA) is an n-6 polyunsaturated 20-carbon fatty acid taking important immunomodulatory roles in infant growth, brain development, and health. However, one of the major drawbacks of polyunsaturated fatty acids is their high susceptibility to oxidation followed by unpleasant odors. Microencapsulation has been proposed as an excellent strategy to solve these problems. In this work, coaxial electrospray was utilized to fabricate AA/zein microcapsules with core-shell structures which were verified by SEM, transmission electron microscopy, and confocal laser scanning microscopy. Microcapsules morphol. was conveniently controlled through electrospray parameters and AA was centralized in the core. The microcapsule diameter ranged from 1 to 7 μm. Results of peroxide values and GC-MS demonstrated that AA in microcapsules possess improved oxidative stability and the unpleasant odors of AA oil was inhibited. The results indicate coaxial electrospray is a useful and convenient tool to fabricate core-shell microcapsules with immiscible materials, which will broaden the potential use of microcapsules as nutrition fortifiers in the food industry. In the experiment, the researchers used many compounds, for example, 5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7Safety of 5-Ethyldihydrofuran-2(3H)-one).
5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of 5-Ethyldihydrofuran-2(3H)-one
