    Effect of brine concentration and curing time on quality attributes of cooked turkey laps
    (American Association for Science and Technology, 2014-11) Apata, E. S.; Popoola, L. A.; Apata, O. C.; Adeyemi, K. O.; Okubanjo, A. O.
    The objective of this study was to investigate the effect of brine concentration and curing time on physicochemical, microbial and sensory characteristics of turkey laps. 4 turkey laps of weight between 1.00 - 1.5kg were divided into 4 treatment groups of brine concentration - 10, 15, 20 and 25% respectively and were cured for 0, 4 and 8 days after cooking at 72°C for 20min. The results showed that Water Holding Capacity (W 1C) and pH of the cured turkey laps increased (p<0.05) as cooking loss decreased p<0.05) thereby increasing the yield of the turkey laps after cooking. Total Viable Count (TVC) and Total Coliform Count (TCC) decreased (p<0,05) while Total Fungal Count (TFC) increased (p<0.05) as brine concentration increased, but the TVC and TCC fluctuated while TFC increased steadily as curing time, increased, not above tolerable levels which made the turkey laps wholesome and safe for consumption. Colour, flavour, texture and juiciness scores increased (p<0.05) as the brine concentration and time of curing increased, but were higher (p<0.05) in turkey laps in treatment 3 that were cured for 4 days. It was observed that treatment 3 (20% brine) and curing for 4 days furnished higher quality attributes of turkey laps as pH, WHC and moisture were high considerably thereby increasing the yield while cooking loss decreased. Also the microbial, counts were lower while colour, flavour, texture and juiciness were higher. In the overall assessment of turkey laps, those cured with 20% brine for 4 days were most acceptable to sensory panel members.

    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.

    Effect of different solar drying methods on quality attributes of dried meat product (kilishi)
    (Canadian Center of Science and Education, 2013) Apata, E. S.; Osidibo, O. O.; Apata, O. C.; Okubanjo, A. O.
    This study was conducted to evaluate the efficiency of four methods of sun drying kilishi after preparation. They included Direct Sun drying Method (DSM) as control, Gujarat Energy Development Agency Method (GEDAM), National Institute of Oceanography Method (NIOM) and Kwatia Drying Method (KDM) each of the methods constituted a treatment viz, A, B, C and D. Meat (Beef) weighing 640 g was purchased and used for this study. The meat was divided into 4 equal parts of 160 g per treatment. They were sliced into length between 0.17 and 0.20 cm in thickness and dried between 4 and 5 hours to reduce the moisture to at least 40% before slurry infusion. The slurry ingredient components were ground and mixed to form a paste. Semi-dried meat were immersed in the slurry for one hour and later stabilized by roasting on charcoal fire for 5 minutes and later dried out in drying media tested in this study. The yield, chemical and sensory properties of kilishi were determined. The results showed that method B gave the highest (P < 0.05) yield of kilishi, chemical attributes as well as sensory properties of kilishi followed by method C. It is suggested that method B and C be developed and produced in commercial quantity for use in drying kilishi in the tropics due to their high efficiency.
