Abstract

ABSTRACTThe objective of this work was to investigate the effects of pan frying on the formation of two typical advanced glycation end products (AGEs) named Nϵ-carboxymethyllysine (CML) and Nϵ-carboxyethyllysine (CEL) in prepared chicken breast. The marinated chicken breast was pan fried for 1 to 6 min, and then protein, fat, moisture, carbonyl, sulfhydryl, thiobarbituric acid reactive substances, chroma (a*, b*, L*), absorbance at 294 and 420 nm, and AGE (CEL) levels were measured once a minute. Pearson's correlation was determined and indicated that moisture was significantly negatively correlated with Maillard reaction and AGEs (P < 0.05), fat and protein contents were significantly positively correlated with AGEs (P < 0.05), and a* values were positively correlated with Maillard reaction and CEL (P < 0.05). Protein and lipid oxidation played an important role on the correlation of AGEs. In conclusion, Maillard reaction and oxidation reaction are two important factors affecting AGE formation.HIGHLIGHTS
