Quality attributes and safety of processed meat products in Ibadan, Nigeria

Abstract

Consumption of processed meat products has greatly increased due to availability and accessibility of ready to eat meat products. Despite increased patronage of ready to eat meat products, food safety implication of processed ready-to-eat-meat products is of global concern. Against this background, this study was aimed at assessing the quality and safety of processed ready to eat meat products sold in Ibadan. Samples of asun, suya and kundi were randomly collected from four selected markets in Ibadan metropolis and subjected to chemical analyses. The total cholesterol content in suya (1538.00 mg/100mg) was significantly higher (P<0.05) than in asun (1277.60 mg/100mg) and kundi (1277.60 mg/100mg). Kundi had significantly (P<0.005) higher crude protein (70.66 %) and ether extract (23.42 %) than asun with 20.17 % and 10.85 % ether extract, respectively. Lipid peroxidation of suya (6.18 mg/MDA/kg) at day 28 was significantly higher (P<0.05) than kundi (4.50 mg/MDA/kg) and asun (4.19 mg/MDA/kg). The total polycyclic aromatic hydrocarbon (TPAH) was 5.31μg/kg in suya, 2.02μg/kg in asun and 1.55μg/kg in kundi. The total heterocyclic aromatic amine (THAA) was 51.66 ng/g in suya, 28.12 ng/g in asun and 23.70 ng/g in kundi. The total heterotrophic bacteria count in suya (28.17 ×10-3cfu/g) was higher than in kundi (11.19 ×10-3cfu/g) and asun (3.99×10-3cfu/g). Therefore, safe keeping and quality of suya in Ibadan metropolis was low based on the above parameters measured.
