Investigation the Effects of Application of Nano-Composite of SiL and TiO2 0n polyethylene Packing for Preserving the Date Against Microbial Variations During Warehousing

As the date is one of the most important products in Iran, its the prominent role in nano technology for packaging and preserving of foods, has been surveyed in this regard. The microbial change of date in 2 temperatures (4°C and 25°C) with 2 different packages (polyethylene without nano composite and polyethylene covered by Silver nano composite and TiO2) has been scrutinized for 4 months. The result of this essay shows that making use of these nano ingredients in package of dates could reduce the microbial burden significantly. The activity of these nano particles led to obliterate micro organisms activities in these 2 conditions. Consequently the date with nano package can be preserved with out undesirable changes under ambient and refrigerator temperature for 4 months.
