Description
The method is applicable to the determination of tin in fruits and vegetables in the concentration range 10-500mg/kg. It is a rapid method, especially suitable for routine determination of tin in canned fruits and vegetables contaminated with migrated tin from the can. The method can be applied with the prescribed amount of sample to products with a maximum total dry matter of 30%. Products with higher total solid contents can be analysed using smaller sample amounts after corresponding dilution with deionised water. Fruits and vegetables are digested in hydrochloric acid at 80ºC and the tin content is determined by flame atomic absorption spectroscopy.
