  • Protein quality indices of sandbox (Hura crepitans) seeds
    International journal of food agriculture and environment, 2020
    Co-Authors: M A Fowomola, A A Akindahunsi
    Abstract:

    The protein quality indices of Hura crepitans Linn seeds were investigated. This was carried out by feeding male weaning albino rats (21 to 22 day old) of the Wistar strain on diets formulated with cooked defatted, cooked undefatted, raw defatted and raw undefatted Hura crepitans seeds. Water and feeds were supplied ad-libitum throughout the experimental period. Six weight changes were also taken by weighing the rats at the beginning of the experiment and every two days intervals till the end of experiment. Faeces of each group were bulked, dried at 85°C, weighed and ground into powder for faecal nitrogen estimation. In addition, the nitrogen content of the urine from each group was also determined. The results obtained from nitrogen determination were used to calculate the protein quality indices of the Hura crepitans seeds. The results showed that defatting and cooking processes significantly increased (P

  • nutritional quality of sandbox tree Hura crepitans linn
    Journal of Medicinal Food, 2007
    Co-Authors: M A Fowomola, A A Akindahunsi
    Abstract:

    Antinutrient, proximate, mineral, fatty acid, vitamin, and amino acid analyses of sandbox tree (Hura crepitans) seeds were carried out. The results of antinutrient analysis showed that H. crepitans...

The results obtained from nitrogen determination were used to calculate the protein quality indices of the Hura crepitans seeds. The results showed that defatting and cooking processes significantly increased (P<0.05) the protein quality indices of the Hura crepitans seeds; true digestibility (54.17′1.25 to 93.6′0.46), true biological value (86.37′0.58 to 96.4′0.10), protein energy ratio (0.61′0.02 to 1.67′0.12), net protein ratio (0.08′0 to 2.54′0.16), protein retention efficiency (1.28′0.0 to 40.69′2.59) and net protein utilization (0.073′0.003 to 0.3431′0.02). The results of phytochemical analysis show that alkaloid, saponin, oxalate, tannins, cyanide, phytate and trypsin inhibitor are present in Hura crepitans seeds. Therefore, the sandbox seed can be used as an alternative source of animal feeds after defatting and cooking.

  • ftir studies of thermal stability of the oils and methyl esters from afzelia africana and Hura crepitans seeds
    Renewable Energy, 2016
    Co-Authors: I M Ogbu, V I E Ajiwe
    Abstract:

    Fourier Transform Infrared (FTIR) spectroscopy was used to study thermal stability of the oils, methyl esters and esters/diesel blends from Afzelia africana and Hura crepitans seeds in comparison with petroleum diesel. Biodiesels are prone to oxidative degradation due to their chemical nature and the degree of this varies with feedstock. Information on the thermal stability of various potential biodiesel feedstocks is very vital for their application. In this study, the samples were exposed to high temperatures between 28 °C and 300 °C for a residence time of 10 min. Fuel degradation was monitored by tracking changes in peak intensities around 3442 cm−1, 1740 cm−1, and 734 cm−1 corresponding to OH of hydroperoxides, CO of carbonyl compounds and carbon-hydrogen bending out-of-plane of CC respectively. Thermal oxidation commenced at about 150 °C with hydroperoxides formation. CO and CC bonds in the samples were shown to be fairly stable within the exposure time. Hura crepitans showed higher thermal stability than Afzelia africana.
