摘要:Carob pekmez, a traditional concentrate, has long been produced from Ceratonia siliqua L. for human consumption in Turkey. 5-hydroxymethylfurfural (5-HMF) is a quality parameter for carob pekmez and other concentrated food products. High levels of this compound are not desirable in pekmez because this may cause mutagenic effects on human metabolism. 5-HMF formation depends on both the sugar content and the acidity of the product. The results of this study show that although a the total sugar concentration was high in carob pekmez (62.80 g/100g) the 5-HMF concentration after the thermal process was only 12.25 mg/kg, which is also lower than Codex Standard, and may possibly be due to its low acidity. The data revealed that carob pekmez is a high source of minerals such as; potassium (1057.3 mg/100g), phosphorus (77.8 mg/100g), magnesium (55.6 mg/100g), and calcium (314.9 mg/100g as well as sugars. The aim of the study was to determine the composition of carob pekmez and content of 5-HMF during its production in the Mediterranean and Aegean basin of Turkey.
