| titleOfInvention | Method for measuring carotenoid content in red-yolk duck eggs |
| abstract | The invention discloses a method for measuring the carotenoid content in red-yolk duck eggs, and belongs to the field of chromatographic detection. According to the invention, a sample is extracted by acetonitrile, condensed and degreased by n-hexane, and is separated by an Agilent Poroshell120EC-C18(4 mu m,4.6 mm multiplied by 100mm) chromatographic column, 20mmol/L ammonium acetate and acetonitrile are taken as mobile phases for gradient elution, the flow rate of the mobile phases is controlled to be 1.0mL/min, the detection wavelength of a diode array detector is 471nm, and the determination of the carotenoid content in the red-heart duck eggs can be completed within 25 min. The method is simple to operate, good in separation degree, high in sensitivity and accuracy, and provides method reference for determining the carotenoid content in the red-yolk duck eggs. |
