ABSTRACT
With the rising worries of potential metal contamination in cooked noodles, this study aimed at unravelling, for the first time, the possible source of metal contamination in cooked noodles. Noodles cooked with full spices (CWFS), cooked with half spices (CWHS), cooked with quarter spices (CWQS), and cooked with no spices (CWNS control) and their spices were analysed for metals using inductively coupled plasma-atomic emission spectrometry. The microbiological quality of the noodles was also evaluated. Metal concentrations in cooked noodles varied with spice quantity. Noodles CWFS had the highest significant (p < 0.05) concentration of Pb (0.36 ± 0.12 mg/kg), Ni (1.05 ± 0.01 mg/kg), Cd (0.07 ± 0.04 mg/kg), Co (0.02 ± 0.002 mg/kg), and Na (9.45 ± 0.04 mg/kg), compared to the control (CWNS). The mean Pb and Ni of spice and cooked noodles were above the WHO acceptable limits for food and could be harmful to consumers. Pearson's correlation and PCA showed that packed noodle spices introduced metals into the cooked noodles. Although the hazard indices (adults and children) in all noodle's groups were less than 1, children still had the potential to contract cancer from Ni exposure because the carcinogenic risk values of CWQS (2.87 × 10-4), CWHS (3.03 × 10-4), and CWFS (3.21 × 10-4) were greater than 10-4. Microbiological analysis revealed the presence of potential pathogens that showed multidrug resistance and the ability to elaborate protease and amylase enzymes. Given the impending chronic health risks inherent in processed noodles, consistent consumption should be avoided.
