Item Sensory and physicochemical evaluation of suya produced from various round muscles(Animal Science Association of Nigeria, 2016) Gandi, B. R.; Olusola, O. O.; Abunwune, R. N.; Makama, R. S.; Abdu, S. B.A study was conducted to evaluate Suya produced from various round muscles (Rectus femoris, Semi-tendinosus, Biceps-femoris, Semi membranosusand Vastus lateralis) for organoleptic and physiochemical properties. The study was carried out using a completely randomized design. The result from the experiment showed that the fat content was not significantly (P>0.05) affected by the muscle types. The score for overall acceptability on a five point hedonic scale indicated that the consumers preferred Bicepsfemoris which was significantly (P< 0.05) different from other round muscles. Water holding capacity was observed to have influence on other qualities such as flavor, juiciness and tenderness. Product yield was lowest (70.20%) in Vastuslateralis, indicating a good yield from all muscles. It was concluded that the prime cuts, apart from resulting in Suya with high prices are not necessarily better than Suya from less choice parts of the carcass (Rectus femor is, Semi-tendinosus, Biceps-femoris, Semi membranosus and Vastus lateralis) in terms of product yield and eating qualities.Item Quality characteristics and microbial status of beef smoked with different plant materials(Animal Science Association of Nigeria, 2014-09) Gandi, B. R.; Olusola, O. O.; Bawa, G. S.A study was conducted to evaluate the effect of smoking beef using different plant materials as sources of smoke in Zaria, Kaduna State. The effect of smoke from four plant materials (Acacia raddiana, Eucalyptus camaldutensis, Azadirachta indica and Cocos nucifera) on organoleptic, microbial and physicochemical properties of smoked beef was evaluated. There was no significant (P>0.05) difference among the sources of fuel wood tested on the overall acceptability of smoked meat. The organoleptic scores (1.40-3.50) were lowest for beef smoked with in C. nucifera and highest for beef smoked with A. raddiana (standard check). The pH values were within the accepted limit (5.5-6.5). Percentage thermal shortening was highest (7.00%) in beef smoked with A. raddiana. Total viable counts/Aerobic plate count, coli-form counts were all within safe limits (i.e. <1/2 million/g). It was concluded that Eucalyptus camaldutensis (Turare), Azadirachta indica (Neem) and Cocos nucifera (coconut husk) are good sources of fuel wood and can be used as an alternative to Acacia raddiana for smoking beef.Item Nutritive and Organoleptic characteristics of kilishi as affected by meat type and ingredient formulation(Journal Management System, 2012) Olusola, O. O.; Okubanjo, A. O.; Omojola, A. B.Kilishi is a ready to eat intermediate moisture meat which is highly relished. The product is traditionally prepared from beef infused with spices and defatted groundnut paste. This study tried to appraise the eating quality of kilishi as affected by meat types and ingredient formulation. Three different kilishi recipes viz fresh, frozen and oven dried groundnut paste representing recipes 1, 2 and 3 respectively were formulated and used for the preparation of pork and beef kilishi in a completely randomized design. The nutrient composition and eating qualities of each kilishi type were evaluated. The result obtained showed that kilishi from the recipes were similar in crude protein with a value ranging from 55.47 – 62.33% while the ash content was highest (P>0.05) in beef kilishi from recipe 1. The colour rating was highest in all pork kilishi irrespective of the recipe. The panelist also rated pork kilishi higher in juiciness with a value range of 3.50 – 4.30 as against values of 1.80 – 4.40 for beef kilishi. Beef kilishi from recipe 1 had the highest flavour rating while the overall acceptability was highest in both products from recipe 1 with values of 6.30 and 5.20 for beef and pork kilishi respectively. The result obtained in this study showed that the use of recipe 1 with fresh groundnut paste was better in product qualities than frozen or oven dried groundnut paste.Item Yield and quality evaluation of kundi (an intermediate moisture meat) prepared from camel, beef, and chevon(Academic Journals, 2009-04) Omojola, A. B.; Kassim, O. R.; Fakolade, P. O.; Olusola, O. O.Kundi is an intermediate moisture meat (IMM) product conventionally prepared from camel meat (CM). There is a dearth of information on the production as well as*the nutritional and eating qualities of kundi from other meat types. An experiment was conducted in a completely randomized design to evaluate yield, nutrient composition and sensory characteristic of kundi prepared from CM, beef and chevon. The protein content of fresh CM (22.58%) was higher (p < 0.05) than the values of 19.57 and 20.83% obtained for beef and chevon respectively. The result showed that fresh beef has at least (p < 0.05) drip loss value of (2.46%) as against 4.03 and 3.53% obtained for CM and chevon respectively. Cooking loss values were 19.30, 21.26 and 20.36% for beef, CM and chevon respectively. Beef gave the least shear force value (6.68 kg/cm3) as compared to 8.39 kg/cm3 for CM and 7.06 kg/cm3 for chevon. The product yield ranged from 33.61 to 38.93%. Kundi from each of the 3 meat types contained about three times the protein in their respective raw meat. The ash content increased from 1.50, 1.05 and 1.31% in raw beef, CM and chevon to 5.80, 4.37 and 4.40% in kundi from corresponding meat type. Kundi from chevon was rated highest (p < 0.05) for flavour juiciness and tenderness while beef kundi (BK) was rated highest (p < 0.05) for colour. Camel kundi (CK) was rated least by the panelist in virtually all parameters scored. . The possibility of producing Kundi from beef and chevon will increase the consumption of the product especially by majority of consumers with aversion to camel meat.
