- Abstract
Ultrasound-assisted extraction method was applied to extract the anllioi yanins from selenium-enriched purple potato, and the optimum extraction conditions for anlhocyanins in selenium-enriched purple potato were obtained bv resjxmse surface methodology; the phosphoric acid concentration of 1. 0%, the solid-liquid ratio at 5, and the extraction time of 19 min. Under these conditions, the yield of anlhocyanins in selenium-enriched purple potato reached (0.409 ±0.010) mg/g (RSD =2.51%, n=3). The extraction of anlhocyanins from selenium-rich fresh purple potato with dilute phosphoric- acid has the advantages of less acid consumption and good extraction effect.
