Abstract: Low temperature display cabinet sales mode was proposed to solve the problem appeared in sales process of Trichiurus haumela. Quality changes in the low temperature display cabinet sales were measured and compared with farmer's market sales and supermarket sales. The sensory evaluation, microbial and physicochemical indicators including pH value, total volatile basic nitrogen (TVB-N) , trimethylamine (TMA-N) , thiobarbituric acid (TBA) , K value of Trichiurus haumela were analyzed in these selling processes. Results showed that the shelf-life of farmer's market and supermarket sales mode were 3d and 4d, respectively. The shelf-life of low temperature display cabinet sales mode was 6d, which extended the shelf-life with 2³d and should be promoted.
