To improve the drying quality of shepherd's purse,fresh shepherd's purse was used as the raw material and subjected to segmenting,flattening,and segmenting+flattening treatments to explore their effects on the drying characteristics and quality of shepherd's purse.The results indicated that the VC content,total phenolic and total reducing power of the segmented shepherd's purse were significantly higher than those of other treatment groups(P＜0.05);the swelling power,water retention capacity and total flavonoid content of the flattened shepherd's purse were significantly higher than those of other treatment groups(P＜0.05);the drying rate,soluble protein,and reducing sugar content of the segmented+flattened shepherd's purse were signif-icantly higher than those of other treatment groups(P＜0.05).Upon comprehensive comparison,segmenting and flattening treatments were recommended as the preferred pre-treatment methods for shepherd's purse.This research provides theoretical support for expanding the application scenarios of shepherd's purse and develo-ping related industries.
