Objective:To study a new method for rapid distinction between the genuine and fake fermented soy sauce or vinegar.Methods:By using the oxidants of the potassium dichromate
the unique ingredient of the genuine fermented soy sauce or vinegar was oxidized
under the acidic condition
which would obviously change the color of potassium dichromate.Results:Genuine soy sauce or vinegar could make the color of 2% potassium dichromate solution turn into green or blue from orange.while on the same condition the blended soy sauce and vinegar failed.Conclusion: This method can distinct qualitatively between genuine and fake fermented soy sauce or vinegar rapidly
simply and accurately
More-over it needs only a small sample quantity
and with high sensitivity.
