Data on concentration of lipid hydroperoxides in five potato cultivars

This study aimed to determine the concentration of lipid hydroperoxides in the fruit juice of five industrial potato cultivars and to assess whether significant differences exist among them.

The dataset includes a hydrogen peroxide standard curve and measurements from five potato cultivars analyzed in biological triplicate. The standard curve consists of ten data points ranging from 1 to 80 µM hydrogen peroxide (H₂O₂), along with their corresponding absorbance values at 500 nm. These data show a linear relationship between hydrogen peroxide concentration and absorbance.

Below the standard curve, absorbance values for Folch extracts from three biological replicates (R1, R2, and R3) of each potato cultivar are presented. Corresponding blank-corrected absorbance values (solvent + reagent) are also provided to account for background signal caused by color development in the reagent over time.

The values labeled R1–R3 [H₂O₂] (µM) represent the hydrogen peroxide equivalent concentrations in each sample, calculated using the standard curve.

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

Overall, the data reveal substantial variation in lipid hydroperoxide concentrations among biological replicates within each potato cultivar, limiting the ability to detect significant differences between cultivars.
