The effect of aldehydes from lipid oxidation on the generation of heterocyclic amine 2-amino-1-methyl-6-phenylimidazo [4,5-b] pyridine (PhIP) during pan-frying of golden pompano fillets was investigated. It was observed the aldehydes that contribute to thiobarbituric acid reactive substances (TBARS) value significantly promoted PhIP generation ( p < 0.05). The defat treatment of fresh fish tissue significantly reduced the PhIP formation in pan-fried products ( p < 0.05). During pan-frying, massive aldehydes were generated in a time-dependent manner with acrolein, propanal, hexanal, 4-hydroxy-nonenal (HNE), and 2,4-decadienal (DDE) as the abundant species. In the established chemical model, these aldehydes congruously promoted PhIP formation with the increased concentration, especially acrolein, HNE and DDE. Therefore, aldehydes could significantly enhance the PhIP generation under processing. However, except for propanal and hexanal, the promoting effect was slightly decreased with high levels of aldehydes addition due to the strong electrophilic properties and participation of reaction with the amino group of phenylacetaldehyde, creatinine, even PhIP.

This study aimed to reveal the effects of steaming, frying and boiling on the sensory and quality of the cooked crucian carp. 46, 27 and 37 volatiles were detected in the steamed fish, fried fish (FF) and boiled fish (BF), respectively, of which 7 were identified as the key volatiles. Compared with the BF and FF, the SF was richer in esters, aldehydes, alkenes and the kinds and contents of the key volatiles. The contents of moisture and crude protein were the highest in the SF. The FF exhibited the most distinctive aroma profile, much possibly associated with the highest thiobarbituric acid reactive substances (TBARS) value observed in the FF. The content of total free amino acid in the BF was the lowest while the content of umami amino acid content in the SF was the highest ( p < 0.05). The nutrition of fatty acids was highest in the SF due to its highest ƩUFA/ƩSFA ratio. PLS-DA analysis showed that SF was positively correlated with the most key volatiles and several free fatty acids. These results indicated that the flavor and nutrition of SF were the highest, providing appropriate cooking methods of crucian carp for the standardized production of bean paste fish.

The production and distribution of 2,5-dimethylpyrazine (2,5-DMP), a key volatile flavor compound, are associated with the frying of skipjack tuna steaks. In this study, an intestinal villus-like chip was fabricated to quantitatively detect 2,5-DMP in multiphase systems based on surface-enhanced Raman spectroscopy (SERS). The chip exhibited excellent SERS performance with an enhancement factor of 1.16 × 10 8 , excellent uniformity and reproducibility, and low detection limits of 6.49 pg/mL, 0.182, and 0.920 ng/mL for 2,5-DMP solid, liquid, and gas models, respectively. The results indicated the 2,5-DMP content with growth rates in the order of frying steam > frying steaks > frying oil, and the 2,5-DMP content in frying steam was linearly correlated (R 2 = 0.992) with the trend of the acid value and total polar compounds in frying oil. Therefore, this strategy for achieving the reliable detection of 2,5-DMP can assist in monitoring the frying process and food safety.
