1. one kind utilizes the method that fast gas chromatography Electronic Nose differentiates Silurus asotus fish fishy smell, it is characterised in that: comprise the steps:
(1) take Silurus asotus fish meat to be stored under 3-5 DEG C of environment；
(2) Silurus asotus fish minced fish meat sample 2g to be detected is put in the airtight sample bottle of 20mL of fast gas chromatography type Electronic Nose fingerprint analysis system；
(3) minced fish three material time points in cold storage procedure are chosen, when namely just slaughtering when starting point, pH minimum point, pH > 7.0 flesh of fish corruption, gather the volatility main component of Silurus asotus fish minced fish meat sample by fast gas chromatography type Electronic Nose, obtain the distance map of the major volatile constituents chromatogram of minced fish meat sample, integral analysis result, principal component analysis figure and volatile material；
(4) adopt chemical database to carry out qualitative to the volatile compound in sample, it is determined that the volatile compound contained in flesh of fish sample, determine the fishy smell material composition in minced fish meat with this；
Described fast gas chromatography type Electronic Nose is the HeraclesII Electronic Nose fingerprint analysis system of AlphaMOS company of France；
Running parameter used by described HeraclesII Electronic Nose fingerprint analysis system is: adding thermal oscillation temperature is 70 DEG C, heating duration of oscillation is 900s, sampling volume is 3000 μ L, sample introduction speed is 200 μ L/s, and injector temperature is 200 DEG C, and the sample introduction persistent period is 20s, the initial temperature of column temperature is 40 DEG C and keeps 5s, the temperature-programmed mode of column temperature is that 4 DEG C/s 270 DEG C keeps 30s, and acquisition time is 93s, and detector temperature is 270 DEG C.
