Investigation of a novel analysis method for the determination of new biomarkers for alcoholic beverage consumption.

2022年，我们重点分析了一种苹果酸酯，由于缺乏参考标准，我们很难确认其同一性。这种衍生物是我们重点研究的化合物之一，作为可能的标志物，特别是在白葡萄酒中。我们进行了一项研究，分析了饮用白葡萄酒的志愿者的尿样，我们发现这种衍生品存在于大多数样本中。在接下来的一年里，我们希望确定尿液中这种衍生品的浓度是否与白葡萄酒消费量有关。此外，这种衍生品只存在于白葡萄酒饮用者中，还是存在于其他酒精饮料中？未来的研究将探索将其用作白葡萄酒消费的标志，并调查其检测窗口。

In 2022, we focused on the analysis of a malic acid ester, which we had difficulty confirming the idenitity of because of a lack of a reference standard. This derivative was one of the compounds we focused on as a possible marker, particularly in white wine. We conducted a study where we analyzed urine samples from volunteers who consumed white wine, and we found that this derivative was present in most samples. In the coming year, we want to determine if the concentration of this derivative in urine correlates with the amount of white wine consumed. Also, is this derivative only present in white wine drinkers, or in other alcoholic beverages? Future research will explore its use of as a marker for white wine consumption and investigate its detection window.
