| Summary: | Canned food products started to exist in worldwide market since the .18th century
and the demand grown rapidly from time to time. The people all around
the world prefer to have canned food products compared to the other type of
food packaging as the canned food products are more convenient, easy to serve
and delicious. However, there were so many disadvantages of canned food
products for daily consumptions because the contents may contaminated with
heavy metals. In this study, the assessment of aluminium (AI), iron (Fe), lead
(Pb) and zinc (Zn) were done on three types of food samples which were
Spratelloides delicatulus (sardines), Stolephorus indicus (anchovies) and Bos
taurus (cow meat) from the local and international brands with different product
expiry date. The samples were extracted by using the acid digestion technique
and analysed the selected heavy metals concentrations with the Inductively
Coupled Plasma Optical Emission Spectrometry (ICP-OES). The mean concentration
obtained for the whole samples were found to be 18.6±13.26 mg/kg of
AI, 66.2±33.81 mg/kg of Fe, O.82±0.38 mg/kg of Pb and 57.48±48.48 mg/kg of
Zn. The trend of the concentration of trace metals in all tested canned food
samples was Zn > Fe > Al > Pb. |
