ABSTRACTA study on the effects of post- harvest variables on the yield and quality of Shea butter wascarried out. The Shea nuts acquired from villages were divided into five batches with avillage/uncontrolled sample. Each batch was boiled at different time ranges (0, 15, 30, 45 and60) minutes. Each batch was dried through an oven drying method. Also, each sample wasdivided into two equal parts and was cooked for 30°C (room temperature) and 100°C(temperature of boiling water). Twelve samples of oil were obtained and analyzed in thecentral laboratory of NCRI (National Cereal and Research Institute) Badeggi. The parametersanalyzed with their corresponding range was compare with the ISO (International StandardOrganisation) which are as follows; Yield % 30 – 33, density g/ml (0.89 – 0.93), Iodinevalue (30 – 75), free fatty acid% (1.00 – 3.00), peroxide value (10.0 – 15.0), melting point °C(30 – 40), impurity% (0.09 – 0.2), refractive index 1.4620 – 1.4650), moisture content (0.05 –0.2), saponification value (160 – 190), unsaponifiable fraction (1 – 19) and acid value (2.0 –6.0). Meanwhile, Sample 2 and 3 (rotary dried sample boiled at 0 minute and 15 minute at30°C) gives the highest yield, of all the Shea nuts processed, while sample 1(village/uncontrolled) gives the lowest yield of all the Shea nuts processed, maybe due toimperfection in the extraction skills, since that was the first extraction made.

Abstract The effect of Shea butter rich diet on gentamicin induced nephrotoxicity in rats was determined. Thirty (30) male and female albino rats grouped into 6 (normal, negative, positive, 10%, 20% and 30% Shea butter rich diet groups respectively) of 5 rats each were used for the study. Phytochemical analysis was carried out on the Shea... Continue Reading
ABSTRACT This research work was carried out to examine the physicochemical and phytochemical constituents of honey and Shea butter samples respectively and their antibacterial effect on Staphylococcus aureus and Klebsiella pneumoniae . The physicochemical screening of honey showed that the honey samples used have low water activity, low moisture... Continue Reading
