Abstract
Sixty random samples of raw thigh & breast, half cooked chicken shawerma & shiesh tawook, fully cooked chicken
shawerma and fully cooked chicken shiesh tawook (10 of each) were collected from different markets in Gharbia
governorates and analyzed for biogenic amines by HPLC. The obtained results indicated that the mean values of
histamine, cadaverine and putrescine (mg/100g) were 10.88 ± 0.91, 12.65 ± 1.10 and 4.54 ± 0.32 for raw thigh, 4.54 ±
0.32, 9.86 ± 0.87 and 9.86 ± 0.87 for raw breast 16.56 ± 1.24, 19.81 ± 1.52, and 11.41 ± 0.96 for half cooked shawerma,
12.29 ± 0.97, 16.20 ± 1.08 and 9.98 ± 1.08 for half cooked shiesh tawook, 12.93 ± 1.03, 16.69 ± 1.33 and 8.01 ± 0.63 for
fully cooked shawerma and 11.68 ± 0.97, 11.91 ± 0.97 and 7.47 ± 0.50 respectively for fully cooked shiesh tawook.
According to the permissible limits recommended by EOS (2005) 10%, 30%, 20%, 20% and 20% of the examined
samples of raw thigh, half cooked shawerma, half cooked shiesh tawook, fully cooked shawerma and fully cooked shiesh
tawook were unaccepted. All raw breast samples were accepted as a result of their histamine content. While, 20%, 40%,
30%, 30% and 20% of the examined samples raw thigh, half cooked shawerma, half cooked shiesh tawook, fully cooked
shawerma and fully cooked shiesh tawook were unaccepted. Moreover, raw breast samples were accepted as result of
their cadaverine content respectively. Accurately 10% of half cooked shawerma were unaccepted while all examined
samples were accepted as a result of putrescine content
