Abstract:
PURPOSE: A method for determining Korean kimchi and Chinese kimchi is provided to distinguish Korean kimchi and Chinese kimchi and to analyze country of origin of kimchi. CONSTITUTION: A method for determining Korean kimchi and Chinese kimchi comprises: a step of measuring the content of isotope of a certain element, which is contained in kimchi; a step of generating coefficient with canonical discriminant function which is able to distinguish Korean kimchi and Chinese kimchi; and a step of selecting Korean kimchi from the coefficient. The certain element is gallium, strontium, or cadmium. The isotope of gallium is 69Ga and 71Ga. The isotope of strontium is 84Sr, 86Sr, 87Sr, and 88Sr. The isotope of cadmium is 110Cd, 111Cd, 112Cd, 113Cd, 114Cd, and 116Cd.
