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.
