Phenolic compounds and the colour of oranges subjected to a combination treatment of waxing and irradiation
In: 11th International Meeting on Radiation Processing (IMRP-11), March 14-19, 1999, Melbourne, Australia.
Résumé
The effects of waxing, irradiation dose and storage on phenolics and colour of irradiated oranges were investigated. Mature oranges (Maroc late) waxed or unwaxed were treated with 0, 1 or 2 kGy radiation and stored up to 9 weeks at 20 degrees C and 40-50% r.h. Colour of the oranges, total phenols and flavones in the peel were measured. Phenolic compounds increased with irradiation dose and storage time. Hue angle, value and chroma of the orange colour were more affected by waxing and storage time than the irradiation treatment. Changes in the phenolic compounds were linked with changes in the redness and saturation of the orange colour. Irradiation stimulated synthesis of flavones; waxing controlled changes induced by irradiation.
