Application Research of NIR Technology on the Fast Quantification of the Key Quality Indicators of Antarctic Krill Oil
In this paper, near-infrared spectroscopy technology was used to establish a rapid determination of the content of phospholipids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), astaxanthin and acid value in Antarctic krill oil. Partial least squares (PLS) was used as modeling method. The N...
