Analysis of the characteristic flavor substances of boneless cold‐eating rabbit under different preprocessing treatments

Abstract

Cold-eating rabbit is a local specialty, combined with three different pretreatment methods commonly used in the industry such as directly making, fried after removing blood, and stir-fry after marinating to study the main flavor substances and effects of preconditioning on characteristic flavor compounds. Sensory analysis showed that umami was the strongest, which was the characteristic taste flavor, obtained from the taste substance detection experiment that Glu and 5′-IMP were the characteristic taste substances. Marinating process had a strong umami taste. Volatile flavor compounds were detected, and alcohols and aldehydes were the main volatile flavor substances. There were 23 kinds of volatile flavor substances and nine characteristic volatile flavor substances. The characteristic flavors were lemon, fat, barbecue, fruit, floral, fennel, and smoky flavor; among these, fat, barbecue, and floral flavor were the most obvious. Novelty impact statement This experiment was the first time to study the flavor substances and physical and chemical indexes of cold-eating rabbits, providing theoretical guidance for the industrial production of cold-eating rabbits in Zigong, China. Combined with three different preprocessing methods commonly used in the industrial production of cold-eating rabbits at the present stage, the influence of cold-eating rabbits' product flavor substances and the exploration of characteristic flavor substances were analyzed. This study concluded that the characteristics of the volatile flavor substances were lemon flavor, fat flavor, barbecue flavor, fruit flavor, flower flavor, fennel flavor, and smoke flavor; among these, fat flavor, the roasted meat, and floral aroma were the most obvious, and Glu and 5′-IMP were the characteristic taste substances.
