Biogenic amines determination in some traditional cheeses in West Azerbaijan province of Iran

Biogenic amines (BA) are nitrogenous compounds that possess biological activity. The source of production is the microbial decarboxylation of amino acids. This compounds are found in various types of cheese. The aim of this work was to evaluate the BA content of some traditional cheeses in West Azerbaijan province Iran. For this purpose, ۷۰ samples of Koopeh, ۱۰ samples of Lighvan and ۵ samples of Red Salmas cheeses were obtained from local supermarkets of different cities of West Azerbaijan province. After preparation of samples, biogenic amines content was evaluated by modified HPLC method. The presence of histamine, cadaverine, putrescine and tyramine in tested cheeses were observed. Total amount of biogenic amines was highest in Red Salmas cheese with ۱۴۲۶.۹۱ ppm. It followed by Lighvan cheese and Koopeh cheese with ۱۰۰۸.۹۸ and ۵۱۷.۷۱ ppm, respectively. Putrescine, cadaverine, histamine and tyramine were detected in Koopeh cheese at levels up to ۱۵۶.۰۹, ۲۸۲.۳۴, ۷۰.۸۰, ۸.۴۸ ppm respectively. These amines were detected also in Lighvan cheese at levels up to ۲۷۷.۵۳, ۳۴۲.۷۴, ۳۷.۵۸, ۳۵۱.۱۲ ppm and in Red Salmas cheese samples at levels up to ۴۳۸.۰۳, ۷۰۱.۰۵, ۱۰۵.۲۱, ۱۸۲.۶۲ ppm, respectively. Large amounts of biogenic amines can indicate non hygienic conditions and contamination of used milk for cheese production.
