Effect of utilising different concentrations of food grade vinegar as preservative on the quality of beef
(2022) Apata, E. S.; Adegoke, M. A.; Apata, O. C.; Olugbemi, M. T.; Ogungbayi, G. B.; Okolosi, J. E.
The influence of different concentrations of food grade vinegar as preservative on beef quality was evaluated in this study. Five levels of vinegar concentrations were tested and each constituted a treatment viz: T0 = (control) Freezer, T1 = 5%, T2 = 4%, T3 = 3%, T4 = 2%, and T5 = 1%. 1.5kg beef was purchased, chilled at 4oC for 24 hours, and apportioned to 6 parts of 250g per treatment. Beef samples were injected with vinegar (25 ml) in each treatment using a hypodermic needle and syringe and were immersed in same concentration in plastic containers and preserved for 14 days. The results indicated that vinegar concentrations significantly (p<0.05) affected beef quality fac-tors especially beef in T3 (3%) which furnished lower values of detrimental physical factors; cooking loss (12.23), thermal shortening (5.20) and drip loss (10.40), lipid oxidation mPV (0.11), TBA (0.22), microbial load TVC (4.60), TCC (3.29), TFC (2.38) and TAC (3.43) relative to other levels of vinegar concentrations. The same treatment (T3) elicited higher, cooking yield (87.77), raw meat colour (6.00), protein (20.47), flavour (6.70), texture (6.87) and overall acceptability (7.67) in comparison with other treatments of vinegar. It was recommended therefore; 3% vinegar could be utilized to preserve beef since it enlisted high shelf-life quality factors and acceptability.
Effects of local clay pot and freezer preservation methods on beef quality attribute
(American Association for Science and Technology, 2014) Apata, E. S.; Adio, F. A.; Apata, O. C.; Odio, A. F.; Aderele, G.
This study was carried out to investigate the influence of local clay pot and freezer preservation on quality properties of fresh beef. 30 clay pots were moulded. 6kg of beef was purchased from Ayetoro abattoir and divided into two portions of 3kg wrapped’in banana leaves and each portion constituted a treatment; T1 = Freezer, T2 = Clay pot. The clay pots were sealed containing 100g of beef each and heated on charcoal fire for 1 hour daily, while beef preserved in freezer was divided into 30 parts of 100g and frozen at -18˚C. Physicochemical, microbiological and sensory properties of preserved beef were determined at 0, 7, 14, 21 and 28 days. Data collected were analysed with ANOVA at p = 0.05. Beef in T1 had higher colour score and lower (p<0.05) shear force values, while beef in T2 had higher yield and lower thermal shortening, protein, ash and TBA were higher in beef preserved with T2 while moisture and fat were higher in T1 beef. Microbial load were higher in T1 as well as colour, tenderness- and texture. However, flavour, odour and acceptability were higher in T2. All properties of preserved beef with the exception of cooking loss, thermal shortening, ash, Thiobarbituric Acid (TBA.,, Total Colifomi Count (TCC) and Total Anaerobic Count (TAG) increased as the time of preservation increased. It is suggested that local clay pot be used by those in developing countries where power supply is still epileptic especially in rural areas, and that beef may not be preserved beyond 14 days since beef properties decreased after that period in this study.
Evaluation of patties prepared from combination of beef and antelope meat
(Animal Science Association of Nigeria, 2016-09) Apata, E. S.; Eniolorunda, O. O.; Ayantuga, D. T.; Apata, O. C.; Okubanjo, A. O.
This study was carried out in the Meat Science laboratory of the Department of Animal Production, Olabisi Onabanjo University, Yewa Campus, Ayetoro, Ogun State to evaluate patties prepared from beef and antelope meat. Fresh beef and antelope meat of 3kg each were purchased, chilled and allowed to equilibrate to room temperature 27˚C which were ground. Approximately 2.3 kg of each meat type was apportioned into five parts of 0, 25, 50, 75 and 100 % after mixing the two meat types into 0, 115, 230,345 and 460g of antelope meat. The meat patties samples were cooked using broiling method and cooled at room temperature. Physico- chemical characteristics and organoleptic attributes of the meat product Were determined after cooking. The results revealed that the cooking loss (32.43%) was higher (p< 0,05) at T4 followed by T5 (31.48%) while the patties yield (71.97%) was in TO followed by patties in T2 (70.45%) and T3 (70.35%) respectively. Water holding capacity (WHC) was higher in T2 and T3 (67.00%) and (66.20%) followed by TO with 62.00%, hence lower shear force values of 0.58N, 0.62N and 0.70N. Moisture content (50.90%) was higher (p< 0.05) T1 and T2 (59.15%), protein was higher (p< 0.05) in 75, while fat was least (p<0.05) in T4 (8.25 %) and T5 (8.20%) in cooked patties. Patties in Tl, T2 and T3 with 6.50, 6.80 and 6.62 were accepted mostly as the had higher colour values of 7.25, 6.03 and 6.21. It was observed that inclusion of antelope meat in the patties between 25% and 50% sufficed to provide the nutrients and flavour that consumers needed in meat patties prepared from beef and antelope meat combination in this study. Therefore, antelope meat could be included in meat patties not beyond 50% so that consumers could relish the meat product.
