Soy sauce-based marinade beef (SSMB) is a traditional Chinese cuisine with a unique flavor. Sensory-directed flavor analysis was conducted to identify the key aroma-active compounds in SSMB and their relationship with sensory attributes.
Soy sauce-based marinade beef (SSMB) is a traditional Chinese cuisine with a unique flavor. However, preprecooling and air-cooling tunnels are necessary industrial units in the cold chain for flavor dissipation. Sensory-directed flavor analysis was performed to identify the key aroma-active compounds in SSMB that had just completed (100 celcius), pre-cooled in the brine tanks (45 celcius), and exited the air-cooleded tunnel (10 celcius). We identified 110 aroma-active substances, of which 42 were quantified based on their high flavor dilution factors. Recombination and omission tests identified 29 odorants as the main aroma-active molecules. Additionally, the flavor matrix revealed the relationship between the aroma component expression and sensory attributes. Flavor substances derived from spices, such as eugenol, anethole, and linalool, are enriched during the pre-cooling stage. The different meat attributes of the three samples were primarily related to aldehydes generated from lipid oxidation.
