  • Effective treatments of jojoba and jatropha hulls to obtain phytochemical compounds for industrial, nutritional, and pharmaceutical uses

    • Authors: Akl, E.M.;  Advisor: -;  Participants: Taha, F.S.; Mohamed, S.S.; Wagdy, S.M.; Hamid, S.M.A. (2019)

  • The hulls were ground and sieved. The effects of ultrasound-assisted extraction together with soaking afterwards were investigated. Solvents used were (1, 0. 5 N HCl), (1, 0.5 N-NaOH), and (70 ml ethanol mixed with 30 ml of (1, 0. 5) N HCl or NaOH) and then soaking to reduce the temperature and to enhance the process in order to hydrolyze lignin. The phenolic compounds, flavonoids, and saponins in each extract were determined, and their antioxidant activities were evaluated. Three antioxidant activity methods were applied for each extract: hydrogen peroxide (H2O2) radical scavenging activity, DPPH, and total reducing capability. Bioactive compounds in their natural form were found to possess high antioxidant activities exceeding that of BHT. The NaOH proved to have a great power for...

  • Applications of sand roasting and baking in the preparation of traditional Indian snacks: nutritional and antioxidant status

    • Authors: Kora, Aruna Jyothi;  Advisor: -;  Participants: - (2019)

  • In addition, the complete destruction of seed microflora enhances the shelf life and thus consumer acceptance. The sand-roasted products act as prebiotic dietary fiber and serves as an alternative to polished grains for the consumers. Thus, the simplest, inexpensive, traditional sand roasting method of dry heat application is used for making precooked ready to eat weaning foods and preparation of cost-effective dietary pediatric and geriatric formulations. The technique is also employed for roasting various beans, fryums, nut, and pulse decortication and as a pretreatment process for tamarind kernel powder production, while the sand baking method is widely used for baking cakes, vegetables, meat, fish, eggs and starchy tubers.

  • Metabolic and oxidative status of West African dwarf does at different reproductive stages in southwest Nigeria

    • Authors: Jimoh, Abubakar Olatunji;  Advisor: -;  Participants: Ojo, Olayinka Abosede; Ihejirika, Uchechi Daureen Gift (2019)

  • Result revealed that intense metabolic changes were associated with late prepartum and postpartum does as pronounced in oxidative and biochemical indicators of WAD does. Significant differences were found in serum biochemical indices across the different physiological stages of the doe except for triglyceride and low-density lipoprotein. Antioxidant defense is higher at early and mid-gestation and dry does, through low lipid peroxidation and high antioxidant activity as compared to late gestation and lactation does.

  • Processed cocoa pod husk dietary inclusion: effects on the performance, carcass, haematogram, biochemical indices, antioxidant enzyme and histology of the liver and kidney in broiler chicken

    • Authors: Adeyeye, S.A.;  Advisor: -;  Participants: Ayodele, S.O.; Oloruntola, O.D.; Agbede, J.O. (2019)

  • The PCHM inclusion did not affect (P > 0.05) the performance characteristics of the broiler chicks, except for the feed intake that significantly (P < 0.05) increased in birds fed 8% of PCHM-inclusive diet at the starter phase. The carcass traits, relative internal organ weights, haematological indices and serum biochemical indices of the broiler chickens were similar (P > 0.05) across the dietary treatments. The serum glutathione peroxidase and catalase concentration were higher (P < 0.05) in birds fed PCHM-inclusive diets compared to those fed the control diet. Similar histological myocardiac cell appearances were observed among the birds across the various dietary treatments. Sections show the myocardium composed of the cardiac muscle with peripherally placed nucleus separated by...
