摘要
For the first time, the formation and retention effects of key aroma compounds in ready-to-eat pork roasted using circulating non-fried roast (CNR), microwave heat (MWH), superheated steam (SHS) and traditional burning charcoal (BCC) were comprehensively analyzed. The results showed that 20 out of 50 odorants were key aroma compounds. The 2,3-dimethylpyrazine, trimethylpyrazine, and LPC 18:2-SN1 were potential biomarkers that distinguished roasted pork. Phospholipids, especially phosphatidylcholine (PC), phosphatidylserine (PS), and phosphatidylethanolamine (PE), played a crucial role on the generation of key aroma compounds in roasted pork. Moreover, triglyceride (TG) that included TG (16:0_18:1_18:1), TG (16:0_18:0_18:0), and TG (16:0_18:0_18:1) were responsible for the retention of key odorants. This study further found that appropriate heat transfer conditions (thermal conductivity, specific heat capacity), and water activity contributed to the formation and retention of key odorants in roasted pork. The CNR method could be a promising alternative to the traditional BCC method in roasted pork.
