摘要: 基于超高效液相色谱-三重四极杆串联质谱技术建立了黑蒜中10 种风味前体物质和21 种游离氨基酸同时测定的检测方法。将该方法应用于黑蒜加工过程中特征成分变化规律的研究,结果表明,在温度75 ℃、相对湿度85%条件下,黑蒜中的特征成分含量在加工过程中发生了较大改变。其中,γ-氨基丁酸、S-烯丙基-L-半胱氨酸、异蒜氨酸、谷氨酰胺、甲基蒜氨酸、蒜氨酸、色氨酸和γ-L-谷氨酰-S-烯丙基-L-半胱氨酸变化最为显著,是黑蒜加工过程中小分子代谢物变化的化学标志物。该方法灵敏度高、准确性好,可满足检测需求。

Abstract: An analytical method based on ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-TQ-MS/MS) was established for the simultaneous determination of 10 flavor precursors and 21 free amino acids in black garlic. The method was applied for exploring the changing pattern of characteristic components in black garlic during processing. The results showed that the characteristic components in black garlic changed significantly during processing at 75 ℃ and 85% relative humidity. Among them, γ-aminobutyric acid, S-allyl-L-cysteine, isoalliin, glutamine, methiin, alliin, tryptophan, and γ-L-glutamyl-S-allyl-L-cysteine changed most obviously, and were identified as the chemical markers of changes in small molecular metabolites during the processing of black garlic. The established method has high sensitivity and accuracy, and can meet the detection requirements.

Key words: black garlic; processing; ultra-high performance liquid chromatography-triple quadrupole-tandem mass spectrometry; sulfur-containing compounds; free amino acids
