Effect of Different Packaging Materials and Preservation Temperatures on Pesticide Residues during Storage Periods in Soft Dates (Al-Khalas and Al-Sukkary)Varieties

Abstract

This study was conducted for the purpose of studying the effect ofsome pesticide residues (Pirimophos-methyle, Diazinon, Bifenthrin and Ethion/ppm) on two varieties of soft dates (Al-Khalas and Al-Sukkary) pack in different packaging materials (plastic and carton), storage at different temperatures (freezer, refrigerator, and room temperature) and storage period nine month The Samples were taken from a farm in the Qassim area in Saudi Arabia after harvesting and some pesticide residues were tested. Result showed that the rate of analysis was no significant different (P≥0.05) for type of pesticides (Pirimophos-methyle, Diazinon, Bifenthrin and Ethion/ppm) for all date varieties during the storage period and storage temperature on carton and plastic packaged, but there was a significant different (P≤ 0.05) between two types of pesticide (Cypermethrin and Bromopropylate/ppm) on packaging materials (plastic and carton) during storage periods and storage temperatures where higher value was recorded in Al-Sukkary variety (0.000056 ppm) and lower in Al-Khalas variety (0.000016 ppm) for a first type, while another type was recorded higher value in Al-Khalas variety (0.00442 ppm) and lower value in Al-Sukkary variety(0.00424 ppm).
