Olive samples
Gemlik variety olives (240 fruit/kg) were harvested from Bornova Olive
Research Institutes’ orchard in Izmir, Turkey in two crop seasons.
Olives were harvested by hand in the second week of November with 5.3
maturity index as stated by Arslan and Özcan (2011). Maturity index (MI)
was calculated on the basis of color changes of peel and pulp and varied
between 0 and 7 in eight categories.
Sample names were coded related to processing method; processing style
as dry-salted olives with 2% salt (N), dry-salted olives with 2% salt
and starter culture (K), packaged olives as modified atmosphere packaged
(MP) olives (NMP: dry-salted olives with 2% salt packaged in modified
atmosphere, KMP: dry-salted olives with 2% salt and starter culture
packaged in modified atmosphere), vacuum packaged (V) olives (NV:
dry-salted olives with 2% salt packaged in vacuum, KV: dry-salted
olives with 2% salt and starter culture packaged in vacuum) and
irradiated olives with different dosages (0, 1, 3, 5 kGy) such as NV0,
NV1, NV3, NV5. A flowchart of experimental procedure and abbreviations
were given in Figure 1. The code description of samples were given in
Table 1.
