Using 2D qNMR analysis to distinguish between frozen and frozenthawed chicken meat and evaluate freshness

ARTICLE OPEN Using 2D qNMR analysis to distinguish between frozen and frozen/thawed chicken meat and evaluate freshness Hyun Cheol Kim 1,2 , Ki Ho Baek1,3 , Yee Eun Lee1 , Taemin Kang 1 , Hyun Jun Kim 1 , Dongheon Lee 1 and Cheorun Jo 1,4 ✉ We identified key metabolites reflecting microbial spoilage and differentiated unfrozen meat from frozen/thawed (FT) using 2D qNMR analysis. Unfrozen and FT chicken breasts were prepared, individually aerobically packaged, and stored for 16 days at 2 °C....
