I would like to get advise on the issue below:
Flavouring Powder were sent to 3rd party lab for lab analysis and the result received is contain 17.4mg/kg of Iron (as Fe) . Method used by the lab is ICP-OES. Does this mean that the sample product is contaminated with metal ?
This is the first time we sent for Iron analysis.
The process for this powder flavour is emulsion liquid > spray dry > sieve > pack into LDPE.
The normal parameters that we sent for testing is according to regulation for flavouring are As, Pb, Hg, Cd, Sb, which is always within the limit.
This is the first time it was sent for Iron analysis.
