Properties of Apo Adzuki Been Seed Ferritin Association Induced by Proanthocyanidins
摘要
Abstract
Ferritin and proanthocyanidins are widely distributed in plant tissues,and the interaction between ferritin and proanthocyanidin is of great significance for understanding the food multicomponent system.Purified apo adzuki bean seed ferritin(aASF)and grape seed proanthocyanidins(GSP)were taken as the research materials.The association of aASF in-duced by GSP was investigated using fluorescence spectrum,dynamic light scattering and transmission electron microscopy,etc.The mechanism of interaction between GSP and aASF was also studied.Results suggested that the presence of GSP can lead to the quenching of aASF fluorescence and the association of aASF molecules.Furthermore,with the in-crease of GSP concentration,the fluorescence quenching and aggregation degree were enhanced.Transmission electron mi-croscopy showed that the aASF became aggregated when GSP was added.In addition,antioxidant analysis showed that, compared with GSP,the antioxidizing capacity of GSP-aASF compounds significantly decreased.These findings are benefi-cial for the further usage of GSP-aASF complex in food industry.关键词
