| Abstract: | This method is for determining β-carotene in milk powder with HPLC.The sample was saponificated in basic methanol conditions and β-carotene in the sample could be extracted by using petroleum ether,the β-carotene separated with other consistants in varian 30 cm× 4 mm Si -5 column and detested at uv453 nm. The minimum detestable value is 5. 38 ×10-10g. The variation coefficient cv (%) is 2.04. The revovery is 95. 3%~98. 4%. |
