碩士 / 國立臺灣海洋大學 / 食品科學系 / 94 / The thesis was to study the effect of light and package on marine microalgal feeds. Marine microalgal feeds were made from 4％ Isochrysis sp. CCMP 1324 in the basic tilapia feed. Feeds vacuum (nylon/polyethylene bags, 9.3 ml O2/ M2/ 24 h)- or un-vacuum (polyester, oxygen-permeable)-packaged individually stored at room temperature and were irradiated at 1000 lux absorbed dose for 3 months. Lipid oxidation is one of the key problems associated with the loss of quality of feeds. Lipid oxidative changes in feeds were studied in relation to packing conditions and extended storage under light. Lipid oxidation was measured by peroxide value（POV）and thiobarbituric acid reactive substances（TBARS）. The result shows that vacuum-packed feeds came out to be efficient in controlling fatty acid oxidation. Light exposure influenced lipid oxidation significantly. Lipid oxidation in commercial feeds was stronger than marine microalgal feeds. Storage and package will extend microalgal feeds into new areas.
