Abstract

The present study was conducted to assess the quality of imported frozen liver sold in Assiut markets, Egypt. A total of 100 samples were randomly collected over a 2 months period (January to March, 2020) from poultry slaughter shops, supermarkets and frozen meat markets. The liver samples were evaluated for chemical indicators of spoilage (pH, TVBN "Total Volatile base nitrogen", and TBA "Thiobarbituric acid") and some of the nutritional aspects (percentage of moisture, protein, fat, ash, and carbohydrates, as well as, gross energy (Kcal/100g) and cholesterol content (mg/100g), beside levels of iron (mg/100g). The obtained mean values of pH, TVBN (mg/100 g) and TBA (mg/kg) of the examined samples were 6.38 ± 0.01, 25.76 ± 0.44, and 0.65 ± 0.03, respectively. Of the examined samples, 92 % showed pH value exceeded the permissible limits of Egyptian standards; however, 88 % showed TVBN content within the set limit. The mean values of moisture, protein, fat, ash and carbohydrates (%) were 70.54 ± 0.11, 21.64 ± 0.08, 3.58± 0.12, 1.50 ± 0.018, and 2.74 ± 0.11, respectively. The calculated gross energy mean value was of 133.09 ± 1.06 Kcal/100 g. Additionally, the cholesterol and iron content mean values were 130.85 ± 2.17 mg/100 g and 16.07 ± 0.24 mg/100 g, respectively in the examined imported frozen liver samples. In conclusion, imported frozen liver sold in markets of Assiut city Egypt is of fair quality; it should be consumed sporadically and with care of TBARS, cholesterol and iron potential hazards.
