Abstract
ABSTRACT Advanced glycation end products (AGEs) are generated in all stages of food thermal treatment. In order to reveal the inhibitory mechanism of AGEs, a range of concentration of (−)-epigallocatechin-3-gallate (EGCG) has been added during low-temperature vacuum heating (LTVH), and high-resolution mass spectrometry-based proteomics was applied for identifying and quantifying N-glycosylated proteins, N-glycosylated peptides, and N-glycosylated sites. The results indicated that, compared with atmospheric cooking, LTVH significantly decreased the generation of AGEs. The addition of EGCG has a positive effect on the inhibition of AGEs when the concentration is lower than 2,000 μg/mL, and 200 μg/mL was the optimal concentration.
