HPLC chromatograms of SO, SO-US1 and SO-MF1 at day 0 and day 30 of storage at room temperature (28–30 °C). SO, shrimp oil; SO-US1, shrimp oil extracted from ultrasonicated KBPI-KC-SO microcapsules containing 0.1% SO; SO-MF1, shrimp oil extracted from microfluidized KBPI-KC-SO microcapsules containing 0.1% SO. Astaxanthin content was calculated from peak area.
