METHOD FOR DISCRIMINATING CHINESE CABBAGES CULTIVATED IN KOREA AND CHINA USING SMART NOSE

摘要

PURPOSE: A method for distinguishing Korean cabbage and Chinese cabbage using a smart nose is provided to determine mass of an ion fragment within a certain range using the smart nose. CONSTITUTION: A method for distinguishing Korean cabbage and Chinese cabbage using a smart nose comprises: a step of measuring mass of an ion fragment within a certain range, which is generated from a volatile perfume ingredient of cabbage; a step of analyzing the intensity and dispersion pattern of spectrum using a statistic program and generating a coefficient of canonical discriminant function; and a step of selecting Korean cabbage from the coefficient of generated canonical discriminant function. [Reference numerals] (AA) Korean cabbage(raw specimen); (BB) Specimen pre-treatment; (CC) Generate and concentrate volatile components; (DD) Analyze with an electric nose; (EE) Quantitatively analyze the ion fragments of the volatile components; (FF) Statistical process; (GG) Analyze data using a statistical program such as SPSS; (HH) Determine the place of origin; (II) Time required; (JJ) About 10 minutes; (KK) About 20 minutes; (LL) 2 minutes or less
