摘要： In this study, salicylic acid nanoliposomes (SA@NLs) were used to alleviate chilling injury (CI) in baby ginger by modulating membrane lipid metabolism. SA@NLs were prepared using thin-film hydration method, and characterized in term of morphology, particle size, and stability. The results showed that SA@NLs were nanosized vesicles with an average particle size of 129 nm, demonstrating favorable dispersibility and encapsulation efficiency. SA@NLs treatment effectively maintained the quality index of baby ginger. The SA@NLs-treated group showed lower levels of phosphatidic acid, lysophosphatidylcholine, and lysophosphatidylethanolamine compared to the SA-treated and control groups, indicating the mitigation of the degradation of phospholipids. Meanwhile, SA@NLs treatment exhibited higher unsaturated fatty acid content and the unsaturation index of fatty acids (IUFA) reached 68.96 % at the end of storage, which enhanced cell membrane fluidity and chilling tolerance. These results demonstrated that SA@NLs had potential applications in controlling CI in baby ginger and other cold-sensitive fruits and vegetables.
