Abstract
AbstractBackground and objectivesThe relationship between the different hydrophilic–lipophilic balance (HLB) values of sucrose esters and the retardant effect on the cornstarch retrogradation have not been investigated. The present research was aimed to evaluate the effects of the sucrose esters with different HLB values on the retrogradation properties by analyzing the changes in the crystalline structure and water mobility of cornstarch gels after storage.FindingsAll sucrose ester with HLB value (2–15), especially the HLB 15, could retard the long‐term retrogradation of cornstarch gels. After being stored for the same time, the retrograded cornstarch gels containing sucrose ester of HLB 15 had the lowest hardness, relative crystallinity, and R1047/1022. Compared with the additive‐free cornstarch, the hardness, relative crystallinity, and R1047/1022 of cornstarch with sucrose ester of HLB 15 were significantly decreased by 142 g, 8.66%, and 0.41, respectively, after being stored at 4°C for 7 days.ConclusionsSucrose ester with a high HLB value showed a strong retardant effect on the starch retrogradation.Significance and noveltyThese results suggested that sucrose ester with higher HLB value might be a more effective additive in retarding the retrogradation of cornstarch gels.
