In the proposed method based on the qualitative Seliwanoff test, quantitative determination was carried out by measuring the red color formed by reacting the HMF and Seliwanoff reagent (resorcinol-HCl). Central Composite Design (CCD) was used to obtain optimum reaction parameters. The limit of detection, LOD (2.69 mg kg−1) and limit of quantification, LOQ (8.97 mg kg−1) were established in the model honey matrix. Precision (as RSD for inter and intraday precision) was in the range of 2.52–5.14%. Accuracy results obtained exhibit a good recovery (from 95.83% to 96.65%). Good selectivity and linearity (R2 > 0.99) were also observed. HMF amounts in honey samples determined by the proposed method were found to be in a relatively good agreement with those obtained by the spectrophotometric Winkler method (r = 0.9880) and HPLC-UV method (r = 0.9888).falseHydroxymethylfurfural | Quantitative | Seliwanoff test | Spectrophotometric | ValidationArticle10.1016/j.lwt.2020.11060210.1016/j.lwt.2020.1106022-s2.0-85096849410WOS:0006139318000901391096-1127
