Abstract

This study was carried out to evaluate the safety of soft dates ( AL-Deglet Noor and AL-Sagai); packed in carton and plastic containers ) and stored (for nine months)under freezing(-180c), refrigeration (40c)and room temperatures(250c),Samples were taken from a farm in the Qassim area at October 2017 after harvesting, and microbial growth were tested. Resultsshowed the higher value of microbial load in Al-Sagai cultivar while had lower value in Al-Deglet Noor cultivar (1.500 and 1.208 cfu/g) for bacteria and (2.492 and 1.825cfu/g) for yeasts and mould respectively.
