Item Effect of socio-economic characteristics of hotel guests on acceptability of roasted meat (suya) as hotel menu in Ogun State, Nigeria(2016-10) Apata, O. C.Suya is meat prepared and cooked by roasting on glowing charcoal fire. It has become a popular mass consumer meat snack in Nigeria. It is usually sold along the streets, in club houses, at picnics, state parties, restaurants and around hotel buildings. As a mass consumer fast food, its consumption cut-across ethnic, religious, sex and socio-economic background but its acceptability as hotel menu in Ogun State is not certain, hence this study. Purposive sampling technique was used to select the respondents from zones in Ogun State viz: Egba, Ijebu, Remo and Yewa. Two Communities were selected from each zone while one popular hotel in each community was selected. A total of three hundred and sixty respondents were interviewed, the results revealed that 240 of hotel guests (66.7%) showed indifferent attitudes to acceptability, of roasted meat (Suya) as hotel food item, while 120 out of360 questionnaire respondents (33.3%) accepted Suya as hotel food item. There was significant relationship established between socio-economic status and preference for Suya as hotel menu in Ogun State 41.00.005).Item Evaluation of suya (tsire) – an intermediate moisture meat product in Ogun State, Nigeria(Canadian Center of Science and Education, 2013) Apata, E. S.; Kuku, I. A.; Apata, O. C.; Adeyemi, K. O.A study was conducted to evaluate suya (tsire) an intermediate moisture meat product in Ogun State. Sixty suya sticks were used. Twelve suya sticks were prepared in the laboratory while 12 suya sticks were collected from each zone of the state namely: Yewa, Egba, Remo and Ijebu. They were analyzed for physical, chemical, microbiological and organoleptic characteristics. The results showed that there were significant (P < 0.05) differences in physical properties of suya samples analyzed with suya from Yewa zone having the highest (P < 0.05) water holding capacity and suya prepared in the laboratory and those from Egba zone had the highest (P < 0.05) shear force, while the pH was least (P < 0.05) in suya prepared from laboratory. Moisture content was least (P < 0.05) in suya samples prepared in the laboratory and from Egba zone, while ash content was higher (P < 0.05) in suya from Yewa, Remo and Ijebu Zones. Aerobic bacteria and coliform counts were least (P < 0.05) in suya prepared in the laboratory and from Egba Zone, while lactic acid bacteria were higher (P < 0.05) in suya prepared in the laboratory and from Egba Zone. The results revealed that suya samples prepared in the laboratory were accepted more (P < 0.05) followed by those from Egba and Remo Zones. However, microbial loads observed on Suya (tsire) samples in this study were not as high as those reported by previous workers. Nonetheless, efforts should be made to educate meat and meat products (Suya) processors in Ogun State on the importance of hygiene and proper packaging and preservation to avoid contamination and spoilage of meat products during processing and sale.Item Evaluation of suya (tsire) – an intermediate moisture meat product in Ogun State, Nigeria(Canadian Center of Science and Education, 2013) Apata, E.

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 Antimicrobial activity of ocimum gratissimum extract on suya (an intermediate moisture meat) in Nigeria(African Scholarly Science Communications Trust, 2014) Olusola, O. O.; Oyadeyi, O. S.; Omojola, A. B.; Olugbemi, T. S.Matured leaves of Ocimum gratissimum were harvested and the extracts used to cure Suya (an intermediate moisture meat). O. gratissimum leaves were collected from Oyo state south west region of Nigeria, rinsed in distilled water and squeezed to extract the fluid. The meat used was Semi membranosus muscle from beef carcass, which was trimmed of all visible fat and connective tissues. The meat cut was sliced into sheets of 0.18cm-0.35cm thick and lengths of between 5.0cm-7.1cm. The study comprised five treatments with 10 replicates each in a completely randomized design. Treatment A (TA) served as the control (Suya without O. gratissimum extract(OGE), while treatment B (TB),treatment C (TC), treatment D (TD) and treatment E (TE) were Suya soaked in OGE for ½ hr, 1hr, l½ hrs and 2 hrs, respectively, before coating with Suya ingredients. A total of 50 sticks of Suya weighing from 38.10 - 59.30 grams of sliced meat per stick were prepared for each treatment. The meat on sticks was properly coated with Suya ingredients and arranged around glowing embers of charcoal. The morphological and biochemical characterization of aerobic bacteria, coliform and lactic acid isolates from the five treatments was carried out. At Day 0, isolates from samples of the five treatments include: Aerobic species of Pseudomonas, Bacillus, Micrococcus, and Flavobacterium species. Three Coliform species isolated were: Proteus, Aeromonas and Enterobacter species. The four Lactic acid bacteria isolated were Pediococcus, Streptococcus, Lactobacillus species and Enterococcus feacalis. The bacterial count on Suya meat soaked in OGE at different curing times of ½ hr, 1hr, 1½ hrs and 2hrs differed. The aerobic counts (0.001x105- 2.2x105) were relatively low at the third and fifth days for TC, TD, and TE while for Lactic acid bacteria, the count reduced from 3.0x105 in TA to 0.2x105 in TE. Coliform counts of 6.0x105 and 7.0x105 recorded at day 7 for TA and TB were exceptionally high. O. gratissimum extract, used as a curing agent in suya production significantly reduced the aerobic count of treated meat, thus enhancing the keeping quality of the products.
