摘要:

功能性食醋是食醋产业多元化与高值化发展的重要方向。为评估不同再加工工艺的改良效果,以“华佗药香醋”为对象,采用液相色谱-串联质谱联用(liquid chromatography-tandem mass spectrometry,LC-MS/MS)技术及体外抗氧化活性测定等方法,系统比较了浸泡(25 ℃)与煮沸处理对其营养成分与功能活性的影响。结果显示,浸泡工艺提升了产品的营养成分含量,总有机酸和总氨基酸分别提高了10.43%和30.04%,但未达到显著水平。同时,该工艺还显著增强了样品的抗氧化能力,1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazine,DPPH)和2,2'-联氮-双-3-乙基苯并噻唑啉-6-磺酸[2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid),ABTS]自由基清除率分别提升了87.39%和58.36%(P<0.05)。扫描电镜分析(scanning electron microscopy, SEM)进一步揭示药香醋中存在天然纳米结构,且其形貌、粒径及Zeta电位均受加工工艺调控。结果表明,浸泡工艺可同步提升药香醋的营养成分与抗氧化能力,工艺可调纳米结构为其功能增效机制提供了直接微观证据。

Abstract:

The development of functional vinegars represents a key direction for the diversification and value-added upgrading of the vinegar industry. To evaluate how different reprocessing methods improve the product, we systematically compared the nutritional composition and functional activity of “Huatuo medicinal aromatic vinegar” subjected to either soaking (25 ℃) or boiling, using liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology, in-vitro antioxidant activity assays, and other methods. The results showed that the soaking process increased the nutritional content of the product, with a 10.43% and 30.04% increase in total organic acids and total amino acids, respectively, but did not reach a significant level. Meanwhile, soaking also markedly improved antioxidant capacity, elevating 1,1-diphenyl-2-picrylhydrazine (DPPH) and 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical-scavenging activities by 87.39% and 58.36% (P<0.05). Importantly, scanning electron microscopy (SEM) revealed intrinsic nanostructures within the vinegar, and their morphology, particle size, and Zeta potential were distinctly modulated by the reprocessing method employed. Collectively, soaking is an effective strategy for enhancing the nutritional and functional properties of medicinal aromatic vinegar, and the discovery of these process-tunable nanostructures offers direct microscopic evidence for the enhanced efficacy.
