Can an association between food compatible antioxidants and Semperfresh be an alternative to DPA in scald treatment?

ABSTRACT

Treatment for scald in apples (cv. Granny Smith) using DPA (diphenylamine, 2500 p.p.m.) was compared with treatment with the antioxidants ascorbyl-palmitate (1875 p.p.m.) and n-propyl gallate (4867 p.p.m.). These were applied alone or combined (1875 p.p.m. each), in both cases in 1% Semperfresh [sucrose esters of fatty acids]. Semperfresh was also applied alone. The fruits were stored at 0 deg C in air and evaluated for scald and quality after 2, 4 and 6 months. After 4 months, scald was not reduced with Semperfresh alone but with the addition of the antioxidants there was a slight improvement over the control. After 6 months, the most effective treatment was with DPA. Semperfresh increased CO2 and ethylene levels in the apple core. After 4 months' storage, a decreased O2 level occurred only in coated fruits with the antioxidants but after 6 months it occurred in all coated fruits. Ascorbyl palmitate reduced the level of alpha -farnesene and conjugated triene hydroperoxides (CTH) after 4 months

and delayed scald development slightly but this beneficial effect disappeared after 6 months.
