Abstract：Thetypesandaccumulationlevelsofanthocyaninsinredonionbulbsarediferent，sotheappearancecharacteristicsarediferent.Inordertoachieveadigitaldescriptionofthecolorofredonionbulbsandestablishamethod forpredicting the anthocyanin content，this study utilized the CIELab color quantification system.Bycomparativelyanalyzing the elationshipbetweencolorquantification indicesandanthocyanincontentin30long-dayredonionbulbs，it was found thatthere wasa highly significant positive correlation（ p∈0.001 ）between the anthocyanin content of the bulbs and the colorquantification indices Chroma and CIRG value.There was a highly positive correlation（ p⩽0.01 ）betweentheanthocyanincontentandthecolorquantificationindexaofthebulbs.Therewasahighlysignificantnegativecorrelation ⋅p∈ 0.001）between the anthocyanin content and the color quantification indices L and Hue of the bulbs. Based on these findings，an optimal regression model Y=1.552e1.231X. for rapidly predicting the anthocyanin content of onion bulbs was established.
