security, and the development of low-risk food preservatives is highly needed in food production. For discovering novel flavor molecules with antiseptic function, novel 2-methyl-3-furyl sulfide flavor derivatives were synthesized and evaluated. A wide range of 2-methyl-3-furyl sulfide derivatives were synthesized by reactions of 2-methyl-3-furyl disulfide with cyclic ethers, amides, ketones, and epoxides
食源性微生物侵染严重威胁食品安全,食品生产中迫切需要开发低风险的食品防腐剂。为了发现具有防腐功能的新型风味分子,合成并评估了新型 2-甲基-3-呋喃基硫醚风味衍生物。通过 2-甲基-3-呋喃基二硫化物与环醚、酰胺、酮和环氧化物的反应合成了多种 2-甲基-3-呋喃基硫醚衍生物。所有这些化合物都具有特殊的香气特征和低香气阈值。这些化合物对测试食源性细菌或真菌菌株(大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌、副伤寒沙门氏菌、检测了单核细胞增生李斯特菌、副溶血性弧菌、意大利青霉、黑曲霉、总状毛霉、米根霉)。发现十五种化合物(3a、3b、3d、3e、3f、3g、3h、3i、3j、3k、3l、3m、5a、5b、5f) 对不同的食源性细菌或真菌菌株具有抗菌活性。值得注意的是,风味化合物(3b、3d、3e、3i、3j、3l、3m)的抗菌活性优于对照组(青霉素、两性霉素B和福美双),是很有前景的食品防腐剂。
