TI  - Effects of different calcium oxide dipping concentrations in aroma profiles of pink lady apple cultivar during cold-storage
AB  - Objective: The aim of this research was to assess the profile of volatile compoundschanges during the cold storage in ‘Pink Lady’ apples.Material and Methods: Six-year-old Cripps Pink (Pink Lady) fruits of apple treesgrafted onto M9 rootstock were used as a plant material for this study. The trees werein a commercial orchard in Çanakkale-Turkey. Fruits were carefully picked up by handat the commercial harvesting time. The fruits were dipped into calcium oxide solutions(concentrations of 2 and 4%) during three minutes. Control fruits were exposed todistilled water. Fruits were stored at 0°C and 90% relative humidity for 6 months. Thearoma profiles of apples determined by GC/MS (Gas Chromatography/MassSpectrometry) analysis followed by liquid-liquid extraction. Stored fruits were analyzedfor their volatile contents at the 2nd, 4th and 6th months.Results: Fresh fruits at harvest period contained 15 volatile compounds in total.However, higher levels of aroma volatile compounds were detected in 6 months ofcold storage. According to the chromatography results, control fruits had 24 volatilecompounds, 2% CaO treated fruits had 25 volatiles and 4% CaO treated fruits had 27volatile compounds at the end of the 6 months of cold storage. Apples at the initialstage produced an abundance of hexyl acetate (4.56%), butyl acetate (3.83%), andhexyl hexanoate (1.68%), which confer typical apple aroma characteristics. Mostly,ester production exhibited a fairly broad peak, declining as fruit aged. Isobutyric acid,allyl ester (initial 0.55%) was lower at the beginning of the storage compare to the endof storage (control fruits 0.06%, 2%CaO 0.13%, 4% CaO 0.20%).Conclusion: CaO applications especially 4% concentration had deformation effect onepidermal layer cells on fruit surface. As a result, CaO applications had a significanteffect on aroma enhancement in Pink Lady apples during cold storage.
