The invention relates to the field of food storage and detection and discloses a rapid analysis method for the freshness of mantis shrimps under the cold-storage condition. An electronic nose with a plurality of sensor arrays is used. The sensor arrays comprise a sulfide sensor, a hydrogen sensor, an ammonia-gas sensor, an alcohol sensor, an alkane sensor, a methane-propane-butane sensor, a propane-butane sensor and a nitric-oxide sensor. The rapid analysis method disclosed by the invention has the advantages that mantis shrimp samples can be detected rapidly, the pertinence is strong, the result is accurate and reliable, the detection result can be obtained without damaging the samples, and the applicability is strong. |
