BIOGENIC HISTAMINE IN SALTED FISH
Rafat Mounir Riad;
Abstract
Two hundreds samples of salted fish; fifty of each of Hydrocynos froskalii (Molouha), Alestes baremose (Molouha), Alestes nurse
.(Molouha), Mugil cephalus (Fesiekh) and Sardine/la aurita (Sardines) were collected from Assiut and Cairo markets together with their brine solution when available. The physical character of the examined samples did not show any significant abnormality.
All samples were chemically analyzed for determination of histamine level by T.L.C. method and HPLC method.
The histamine level determined by TLC method in Hydrocynos froskalii ranged from 3.97 to 20.02 with a mean value of 10.14 mg histamine/] 00 gm muscles whereas that of Alestes baremose varied between 3.6 to 24.88 with a mean value of 11 .98 mg histamine/100 gm muscles. Regarding Alestes nurse the mean value of histamine content was
11.82 with a minimum of 4.02 and a maximum of 25.09 mg histamine/I 00 gm muscles. In Mugil cephalus, the minimum, maximum and mean value of histamine content were 5.09, 28.08 and 16.01 mg histamine/I 00 gm muscles respectively. IN Sardine/la aurita. The corresponding values were 8.91, 29.93 and 17.89 mg histamine/JOO gm muscles respectively. The histamine levels in the examined samples were higher than the permissible limits where the percentage of increase was 2.5, 5, 10, 37.5 and 42.5 for the mentioned samples respectively.
As for HPLC method, the obtained results of the examined Molouha, Fesiekh and Sardine samples were: from 4.76 to 19.85 with a mean value
