Selected ion flow tube-mass spectrometry (SIFT-MS) has recently gained interest as an alternative method to traditional GC-MS for the detection of targeted volatile sample compounds, due to its ease of use, its speed and sensitivity, and its potential for real-time quantification. The feasibility of this technique was demonstrated using the case of the production of ethanol during sourdough fermentation. The potential of SIFT-MS as an online monitoring device for food fermentations was further demonstrated by the detection of acetoin in certain sourdough fermentations. This allowed discrimination between sourdough fermentation processes and illustrated the importance of real-time monitoring of food fermentations.
选择离子流管质谱法（SIFT-MS）作为传统气相色谱-质谱联用（GC-MS）技术的替代方法，用于检测目标挥发性样品化合物，最近受到了关注。这是因为它使用方便、速度快、灵敏度高，并且具有实时定量的潜力。通过酸面团发酵过程中乙醇生成的案例，证明了该技术的可行性。在某些酸面团发酵过程中对3-羟基丁酮的检测，进一步证明了SIFT-MS作为食品发酵在线监测设备的潜力。这使得能够区分酸面团发酵过程，并说明了食品发酵实时监测的重要性。
