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.
