FPO-research on skin flecks on Elstar. Skin quality appears to be the key for the solution of skin flecks.

Fruits from the second harvest of the apple cv. Elstar were coated with fish meal (1% solution), starch solution (0.25-2.0%), wax or DPA [diphenylamine] (0.25-2.0%) before storage in ULO [ultra-low oxygen] until early March, and after holding [time not specified] the occurrence of skin flecks and CO2 damage were assessed in a trial at the Proefstation voor de Fruitteelt, Wilhelminadorp, Netherlands, in 1996. Skin flecks were almost eliminated by fish meal as well as starch solution at 2%, but CO2 damage rose from 0 to a maximum of 83%. DPA at 1 or 2% reduced the occurrence of skin flecks without causing CO2 damage. The relationship between fruit quality characteristics, especially colour, at harvest and the occurrence of skin flecks is discussed, and a forecasting system is proposed based on fruit mineral analysis and sugar and acid contents.
