Direct determination of nickel in margarine

Lectures Food Applications


Nickel is used in the production of margarine as a catalyst for hydrogenation. This may lead to residues that could cause allergic reactions. The described solid sampling GFAAS procedure allows a rapid and less expensive product control. 25 Brands of margarine were analysed for nickel contents and except for two samples contents below the detection limit of 0.2 and 0.1 mg/kg have been found.
