Emulsification-based interfacial synthesis of citral-loaded hollow MIL-88A for the inhibition of potato tuber sprouting
Economic value of the global potato harvest is impacted by sprouting during storage. We examined how sprouting might be reduced or eliminated using citral , a naturally occurring component in citrus fruit peel. The current study integrated both loading and sustained release of citral using emulsification-based interfacial synthesis of hollow MIL-88A. The structural properties and compositions of MIL-88A and hollow MIL-88A were confirmed using SEM, EDS, and XRD. BET analysis showed a surface area of 30.36 m 2 g −1 , pore volume of 0.21 cm 3 g −1 , and an average pore radius of 13.56 nm for hollow MIL-88A. Citral was successfully loaded into 10 g of MIL-88A and hollow MIL-88A, with a total citral load of 0.21 cm 3 and 1.82 cm 3 , respectively. The citral-loaded hollow MIL-88A induced a sustained release of citral, which effectively inhibited the sprouting, leading to higher starch content by 41%, lower weight losses, reducing sugar content, α-Amylase, β-amylase, and starch phosphorylase activities by 75%, 55%, 34%, 31%, and 43%, respectively. The citral-loaded hollow MIL-88A might inhibit sprouting by suppressing gibberellin and indole-3-acetic acid while maintaining abscisic acid.
