Evaluation of food microbiome is of major importance since it accounts for the product's organoleptic characteristics and their nutritional value. In this dataset, microbes present in olive samples (‘Kalamata’ variety) stored under modified atmosphere and throughout different time-points of the shelf life of the product are presented, originated after 16S and 18S rRNA sequencing. The different time-points analyzed were: T0 (immediately after packaging), T6 (six months of storage), T12 (12 months of storage) and T18 (six months after the end of shelf life). Sequencing was performed on a MiSeq platform with the MiSeq Reagent Kit v3 (600 cycles). The raw sequence data used for analysis are available in NCBI under the Sequence Read Archive (SRA), with BioProject ID PRJNA688686. Raw reads were analyzed using the QIIME2 pipeline, clustered into Operational Taxonomic Units (OTU) and aligned against SILVA 132 reference database. OTUs are presented in different taxonomic levels for each time-point. These data present valuable information on the microbial communities of table olives, a dynamic niche that affect the final product quality. The data presented are related to the research article “Insights into the evolution of Greek style table olives microbiome stored under modified atmosphere: biochemical implications on the product quality” [1].
