Data on volatile secondary lipid oxidation products in potato fruit juice from five industrial potato cultivars

This study aimed to quantify eight volatile secondary lipid oxidation products in the fruit juice of five industrial potato cultivars and to assess whether significant differences exist among them. Of the eight target compounds, five were successfully detected.

The data file is organized into three sections. In section 1 (yellow 1)), the five potato cultivars are listed along with the measured concentrations of detected volatiles (ng/0.5 mL potato fruit juice, PFJ). Data are based on three biological replicates (R1, R2, and R3), and the mean and standard deviation (SD) have been calculated for each compound. Section 2 (yellow 2)) presents the mean concentrations of the detected volatiles expressed as ng/mL PFJ, while section 3 (yellow 3)) shows the corresponding standard deviations.

The results indicate significant differences among potato cultivars in the levels of volatile oxidation products. Notably, 2-pentylfuran and 2-nonenal are present at relatively high concentrations in PFJ, whereas the other detected compounds occur at lower levels. This pattern provides insight into the predominant lipid oxidation pathways in potato.

Further details on data acquisition are provided in the “Steps to reproduce” section.

Overall, the data demonstrate clear cultivar-dependent variation in the concentration of some key volatile lipid oxidation products.

本研究旨在定量分析5个工业用马铃薯品种的果汁中8种挥发性次级脂质氧化产物，并评估不同品种间是否存在显著差异。在8种目标化合物中，最终成功检出5种。

本次数据集包含三个部分。第1部分（标注为黄色1））列出了5个马铃薯品种以及各检出挥发性物质的测定浓度（单位：ng/0.5 mL 马铃薯果汁（PFJ））。数据基于3次生物学重复（R1、R2、R3），并计算了每种化合物的平均值与标准偏差（SD）。第2部分（标注为黄色2））以ng/mL PFJ为单位，给出了各检出挥发性物质的平均浓度；第3部分（标注为黄色3））则展示了对应的标准偏差值。

研究结果表明，不同马铃薯品种间的挥发性氧化产物水平存在显著差异。值得注意的是，2-戊基呋喃与2-壬烯醛在马铃薯果汁中浓度相对较高，其余检出化合物浓度则较低。该特征可为马铃薯中主要脂质氧化途径的解析提供参考。

综上，本数据集证实了部分关键挥发性脂质氧化产物的浓度存在显著的品种依赖性差异。
