    INVESTIGATING THE MINERAL COMPOSITION OF PROCEESSED CHEESE, SOY AND NUNU MILKS CONSUMED IN ABUJA AND KEFFI METROPOLISES OF NIGERIA

    Milk and its products are needed for proper body building. Processed cheese, nunu and soy milk consumed within Abuja and Keffi metropolises were analyzed for their mineral contents. X1, Y1, Z1 represents soy milk, nunu and cheese from Abuja metropolis while X2, Y2, Z2 represents sample from Keffi metropolis respectively. Calcium (265.53±0.25 mg/mL), iron (1.19±0.92 mg/mL), potassium (162.77±0.02 mg/mL) were found to be higher in cheese milk (Z1) from Abuja than that (225.82±0.13 mg/mL, 1.05±0.60mg/mL and 130.41±0.04 mg/mL) found in Keffi (Z2) examined respectively, though the amount of sodium present (151.0±0.08 mg/mL) in cheese (Z2) from Keffi is slightly higher than that (150.08±0.01 mg/mL) from Abuja (Z1). Also, Soya milk from Abuja (X1) had highest amount of zinc (0.76±0.00 mg/mL) while that of Keffi (X2) was 0.65±0.3 mg/mL, for magnesium and copper, higher values 18.40±010 mg/mL and 0.25±0.02 mg/mL were recorded for soy milk(X2) from Keffi while soy milk from Abuja(X1) had 17.97±0.20 mg/mL and 0.16±0.01 mg/mL respectively. Chromium was dictated in both cheese samples but not dictated in soya and nunu milks from both metropolises. It is seen from the investigation that cheese had more minerals followed by soya milk. Nunu milk sample had the least quantity of minerals; also all the samples analyzed have minerals present in them. Therefore, they are needed for the proper functioning of the body system

    Physical and Proximate Compositions of Selected Milk Products in Abuja and Keffi Metropolis, Nigeria
    (Department of Biochemistry and Molecular Biology, Nasarawa State University Keffi, 2021-05-04) Madu, Paschal Chima; Okpara, M.U.; Shuaibum, B.S.; Isah, J.; Muhammad, Abdullahi Ubana
    Milk and its products have been an important component of nutritional diet. Soymilk, nunu and processed cheese consumed within Abuja and Keffi metropolises were analyzed for their physical and proximate compositions. The pH, specific gravity and total titratable acidity of the samples were within the acceptable limits.The result of the proximate compositions indicated that fat, total solids, total solids non- fat, ash and protein were higher in cheese samples from Abuja and Keffi. The above compositions of soya milk samples from Abuja and Keffi did not vary. But the protein and total solids content of nunu from both metropolises were different. Fibre was found in soya milk samples and its protein and iron contents were higher than that in nunu sample thus a good substitute for alleviating protein malnutrition. At the end of this study, it was concluded that all the milk samples analyzed from Abuja and Keffi have good nutritional values.

    Quality Control Monitoring & Evaluation of Triglycerides, Cholesterol And Inter-Laboratory Assessment of Two Hospitals In Central Nigeria
    (Department of Chemistry, Faculty Of Natural And Applied Sciences, Nasarawa State University, Keffi, 2018-09-09) Tukura, Bitrus Wokhe; Audu, Stephen I.; Abah, J.; Inyanda, D.; Ojile, J.O.; Isah, J.; Alao, B.
    Quality control (QC) is one of the most important impacts on laboratory testing—it ensures both precision and accuracy of patient sample results. The integrity of quality control samples is important to both management of overall quality as well as to meeting requirements of proficiency testing.The study was done to assess the quality control monitoring and evaluation of triglycerides & Cholesterol and also for interlaboratory studies of some haematological parameters[ White blood cell (WBC),Red blood cell (RBC)and Heamoglobin (Hgb), in Nisa Premier Hospital Abuja and the Benue State University Teaching Hospital Makurdi,North central Nigeria.The quality control monitoring& evaluation of Triglycerides and cholesterol were conducted for two consecutive months using the spectrophotometer(kenza240 TXbiolabo France),and the inter -laboratory studies was done in blood samples at both locations. At both locations determination was performed directly using the Automated Haematology Analyzer ((KX-21N Sysmex, USA)).The results of quality control showed that Trends (loss of reliability) and shifts (abrupt changes in the control mean) were noted in the results of this study, there were two major trends in July and more shifts in the month of August than in the month of July for triglycerides and a major trend and two violations of the Westgard Ruler for cholesterol.The results of inter-laboratory assessment of the haematological parameters shows that both imprecision and bias exist between both laboratories.Although imprecision values were generally in the range: 1< CVR <1.5, indicating ―Acceptable to marginal performance‖, the overall bias between laboratories was in the range: SDI >1.5 or SDI < -1.5; In this study, Warning signs were recorded but there was no cause for rejection of the analytical run. These violations typically identify smaller systematic error or analytical bias that is not often clinically significant or relevant.
