Physicochemical quality assessment of Brazilian frozen beef imported into Algeria

Abstract

Background: In recent decades, imported boneless and frozen beef has invaded the Algerian market. However, the true appreciation of the quality of this product can only be obtained by laboratory analyzes and examinations. Aims: The aim of the current study was to assess physicochemical parameters of the imported boneless and frozen beef meat dedicated for human consumption. Methods: Twenty (20) samples of neck, blade bolar, brisket, blade oyster, Forequarter (FQ)/hindquarter (HQ) shin-shank were purchased from the Regional Meat Office in Saida city, Algeria. Physicochemical parameters such as pH, water, ash, protein and fat content were analyzed according to standard procedures. Results: Our results showed a highly significant variability concerning protein and fat content of the five categories of analyzed pieces (p = 0.002). Fat content ranged from 0.43 g to 4.04 g per 100 g of edible portion, for which we found low intramuscular fat contents in the lumps. However, the pH values obtained generally characterized RFN (Red, Firm, and Normal) meat. Conclusions: In view of the results obtained from this study, the overall chemical composition is satisfactory, except for the fat content which constitutes a parameter to be discussed and which depends on the taste of the consumer. Keywords: Frozen meat, analysis, physicochemical quality.
