Abstract

Changes in contents of the S-alk(en)yl-L-cysteine sulfoxides (ACSOs) methiin, isoalliin, propiin, and cycloalliin in onions after boiling, frying, steaming, and microwaving were investigated using Liquid Chromatography Electrospray Ionization-Tandem Mass Spectrometry (LC/ESI-MS/MS). ACSOs contents increased by 34.2-568.0% during frying, steaming and microwaving, whereas ACSOs contents decreased by 32.6-69.4% during boiling. The methiin level in heat-treated onions ranged from 0.18 to 0.47 g/100 g of dry weight (DW), and the cycloalliin concentration in heat-treated onions ranged from 0.31 to 3.50 g/100 g of DW. The amount of isoalliin in processed onions was 0.34-3.32 g/100 g of DW, and propiin was 0.15-1.67 g/100 g of DW. Changes in the ACSO concentrations were dependent on the cooking method. The quality of heat processed onions was evaluated.

摘要

采用液相色谱-电喷雾电离串联质谱法(LC/ESI-MS/MS)研究了洋葱在煮沸、油炸、蒸煮和微波加热后S-烷(烯)基-L-半胱氨酸亚砜(ACSOs)——甲硫氨酸亚砜、异蒜氨酸、丙硫氨酸和环蒜氨酸含量的变化。在油炸、蒸煮和微波加热过程中,ACSOs含量增加了34.2%至568.0%,而在煮沸过程中ACSOs含量下降了32.6%至69.4%。热处理洋葱中甲硫氨酸亚砜的含量为0.18至0.47克/100克干重(DW),热处理洋葱中环蒜氨酸的浓度为0.31至3.50克/100克DW。加工洋葱中异蒜氨酸的含量为0.34至3.32克/100克DW,丙硫氨酸为0.15至1.67克/100克DW。ACSO浓度的变化取决于烹饪方法。对热处理洋葱的品质进行了评估。
