Analysis of Elements and Effects of Common Disinfectants in Common Salad Vegetables

Biol Trace Elem Res. 2024 Mar 6. doi: 10.1007/s12011-024-04135-2. Online ahead of print.ABSTRACTIn this research, firstly, the effect of some cleaners or disinfectants (including washing with water, blue ozone (O3, 0.5ppm), blue benzalkonium chloride (BAC, 120ppm), the combination of two treatments (O3 + BAC)) on the population of two pathogens plant was evaluated, secondly 14 elements (Ca (calcium), magnesium (magnesium), As (arsenic), Al (aluminum), mercury (mercury), Se (selenium), cadmium (cadmium), K (potassium), Iron (Fe), nickel (Ni), zinc (Zn), sodium (Na), manganese (Mn) and lead (Pb)) were evaluated in romaine lettuce and Brassica oleracea, thirdly, the sensory evaluation of the mentioned vegetables with different treatments was investigated during seven days. The results showed the maximum and minimum mean of essential elements were Ca (5334 ± 178 mg/kg in Brassica oleracea) and Se (0.0021 ± 0.0001 mg/kg in Romaine lettuce), respectively. The maximum and minimum mean of toxic elements were Pb (6.26 ± 0.12 µg/kg in Brassica oleracea) and Hg (lower than LOD in Brassica oleracea), respectively. Also, the combined treatment (O3 + BAC) showed the best result, so that the lowest aerobic bacteria population (3.15-3.86 in Brassica oleracea and 3.25-4.17 log CFU/g in Romaine lettuce), yeast and mold (1.58-2.06 in Brassica oleracea and 1.65-2.29 log CFU/g in Romaine lettuce), E. coli (ND-1.23 in Brassica oleracea and ND-1.76 log CFU/g in Romaine lettuce) and S. Typhimuri...
