Composição centesimal, valor calórico, teor de colesterol e perfil de ácidos graxos da carne de búfalo (Bubalis bubalis) da cidade de São Luiz do Quitunde-AL

Buffalo ( Bubalis bubalis ) is an animal that presents significant potential for meat and milk production, but there are few data in the literature regarding the chemical compositions of the derived products. In order to obtain information concerning the levels of fatty acids and cholesterol in buffalo meat, together with the calorific value and centesimal composition, 60 samples of meat produced in the area of Sao Luiz do Quitunde (Alagoas, Brazil) were analysed. Results derived from 20 samples from each of three different cuts of meat, namely rum steak, plain and loin, showed the presence of high levels of protein and water, but reduced levels of lipids when compared with meat from other animal species. Twenty-two different fatty acids were identified in meat samples, and in all meat cuts the main components were C18:1, C18:0, C16:0, C18:2 and C20:4. Despite being saturated, C18:0 is non-atherogenic and accounted for 50% of the total saturated fatty acids present in all three cuts. The polyunsaturated / saturated fatty acids ratios were 0.50 (rum steak), 0.60 (plain) and 0.54 (loin). The ω 6/ ω 3 fatty acids ratio values were 2.1:1 (rum steak), 2.3:1 (plain) and 2:1 (loin). Levels of cholesterol in rum steak, plain, and loin were 83.01, 86.70 and 79.01 mg/100g, respectively. The highest caloric value was found in rum steak cut. Taken together, these results demonstrate that buffalo meat could represent a healthier food option in comparison with other types of meat.
