Abstract

Nano-packaging is among the novel packaging technologies used for increasing the quality and safety of food materials. Nano-coating used in Nano-packaging is an enormous revolution in the export of spoilable products. In this research, 38 caviar packs (5 gr) including 4 nano-free coating packs, 4 nano-silver based 6000 ppm coating packs, 4 nano-silver based 5000 ppm coating packs, 4 nano-silver based 4000 ppm coating packs, 4 nano-silver based 2000 ppm coating packs, and 4 nano-silver based 1000 ppm coating packs were dually inspected for bacteria and fungi. After microbial examinations and spread preparation and gram coloring and detecting the gram bacteria in terms of morphology, further inspection for detecting the bacteria and fungi in specific environments was attempted. After a 24-hour inspection, Staphylococcus aureus and Escherichia coli and Aspergillus flavus and Penicillium were detected in nano-free coated samples. However, there has been a considerable decrease in fungi and bacterial growth in 5000 and 6000 ppm coatings. Eventually, the silver quantity in caviar packs were measured by means of TITRATION method and by applying tirazol and concentrated sulphuric acid, and zero silver leftover content was detected. Moreover, 5000 and 6000 ppm coatings with P<0.05 considerably decreased fungi and bacterial growth. As a conclusion, with respect to the achieved results and based on the fact that there is no penetration of nano particles into caviar, the implemented technology can be used to increase the preservation of valuable products and enhance the export industry.
