Determination of some chemical properties of tarhana during storage; fortified with different amounts of pomegranate seed extract

In this research, biogenic amine content, mineral content, acidity and pH values, total free amino acid content, ash content, colour values (CIE L*, a*, b*), total phenolic compound content and antioxidant activity values of tarhana, which were fortified with pomegranate seed extract in different ratios (0%, 0.5%, 1%, 2%) were evaluated during six months of storage. It has been evaluated that pomegranate seed extract causes increase on total phenolic content, ash content and antioxidant activity values. Putrescine, cadaverine, spermidine, spermine, histamine, tyramine were studied as biogenic amines. Standart addition and internal standart techniques were used for the determination of biogenic amines. Recovery rates were found between 87.0% and 94.6%. It was found that, pomegranate seed extract causes decrease on biogenic amine content of tarhana samples. While the average total biogenic amine content in control group was 894.70 mg/kg, tarhana samples which were fortified with pomegranate seed extracts in ratios of 0.5%, 1%, 2% contained 569.67 mg/kg, 514.52 mg/kg, 424.60 mg/kg total biogenic amine, respectively
