This study aims to present the influence of the organic technology applied to three edible English roses on nutrients and contaminants content. Fresh petals from Falstaff (F), Brother Cadfael (B) and Crown Princess Margareta (C) cultivars and three variants of jam using different ingredients were analysed and determined the content of minerals and contaminants. The results showed significant differences between experimental variants regarding nutrients content. Cu was found at low levels, with a maximum of 2.307 mg kg-1, important result for the organic protection scheme. The highest values were of K found in all variants, in the fresh petals 2143.40-2625.89 mg kg-1 (C), 2378.77-3103.65 mg kg-1 (F) and 2176.13-2903.97 mg kg-1 (B) and in the jam variants 538.77-616.045 mg kg-1 (C), 544.14-685.22 mg kg-1 (F) and 486.02-729.38 mg kg-1 (B). Important quantities of Ca and Mg were found in fresh petal variants. All the analysed samples of fresh rose petals and rose petal jam had contaminants traces bellow the standard maximum limits. Important quantities of minerals were found, expressing the positive influence of the applied organic technology.
