Abstract

One hundred and thirty-five random samples of street vended foods represented by kofta, hawawshi and liver (45 of each) were collected from Benha (15 of each product), Tukh (15 of each product) and Moshtohor (15 of each product) in Kalyobia governorate for determination of their content of histamine and tyramine. The obtained results recorded that, the percentage of occurrence of histamine in Benha city were 73.33, 93.33 and 66.67 % in the kofta, hawawshi and liver samples, respectively. In Tukh center were 86.67, 100 and 73.33 % in the kofta, hawawshi and liver samples, respectively. Whereas in Moshtohor village were 100, 100 and 80.00 % in the kofta, hawawshi and liver samples, respectively. Furthermore, our results showed that the percentage of occurrence of tyramine in Benha city were 86.67, 100 and 73.33 % in the kofta, hawawshi and liver samples, respectively. In Tukh center were 93.33, 100 and 73.33 % in the kofta, hawawshi and liver samples, respectively. Whereas in Moshtohor village were 100, 100 and 86.67 % in the kofta, hawawshi and liver samples, respectively. It could be inferred that regarding the products contamination, hawawshi represented the highest histamine and tyramine contamination followed by kofta then liver. Regarding the locality, Moshtohor represented the highest contamination of both histamine and tyramine followed by Tukh then Benha city.
