Evaluation quality chicken meat during frozen storage

The comet assay was carried out (Deoxyribonucleic acid (DNA) was found in the breast and the thigh), and the degradation of DNA in the chicken sample may be an indicator that the storage conditions were not suitable. It is an indication for the quality of meat called malondialdehyde (MDA). The total volatile basic nitrogen, also known as TVB-N, is an indicator of the degradation of proteins, and this test is used to evaluate the quality of meat. a total of forty frozen carcass samples were collected at random from different Iraqi local markets in Baghdad. Twenty of these samples were extracted from the breast and thigh flesh of the same carcass and subjected to analysis with a comet assay, spectrophotometer, and keldjal equipment. The DNA comet assay revealed the lowest value in frozen breast DNA damage (9.85±1.88), but the result of the malondialdehyde MDA revealed no significant differences between the groups. The findings of the total volatile basic nitrogen TVB-N test showed that frozen thigh meats had a value of (9.19± 0.30) whereas breast meats had a value of (7.81± 0.58).
