Simple methods for rapid determination of sulfite in food ...

1/12/2006, · Two simple methods for sulfite determination in food products were proposed. The modified para-rosaniline (PRA)-formaldehyde method showed a much broader linear range (0.05–5.0 mg l −1 as SO 2) than the commonly used procedure for the ,sulfur dioxide detection, in the atmosphere (0.05–1.0 mg l −1 as SO 2).By using a standard reference color card, this method only needed 5 min to complete ...
