- ItemCharacterization of pectin extracted from muskmelon (Cucumis melo L.)(Journal of Science and Technology, 2021-10) Nyarko, Benjamin; Agbenorhevi, Jacob K.; Wireko-Manu, Faustina D.; Kpodo, Fidelis M.; 0000-0002-8516-7656; 0000-0002-5020-6299; 0000-0002-7949-0502Muskmelon (Cucumis melo L.) fruits are cultivated for their seeds, but the peels are potential sources of pectin for food and pharmaceutical applications. The objective of this study was to extract and characterize pectin from muskmelon peels subjected to two different drying techniques. The pectin was extracted using acid treatment and the structure, chemical composition and functional properties determined. Oven and solar dried muskmelon pectin extracts gave comparable yields (6.48% and 5.27%), high degree of methylation (60.53 and 64.97%) and anhydrouronic acid content of 46.99% and 56.60%, respectively. Intrinsic viscosity was 0.3 gdL-1 irrespective of drying technique used. The pectin extracts from the oven and solar dried muskmelon demonstrated good water absorption (208g/100g and 269g/100g), oil absorption (237g/100g and 152g/100g) and emulsion (50% and 46%) capacities, respectively. The different drying techniques used did not significantly influence physicochemical and functional properties. The findings show that muskmelon pectin are high methoxyl pectin with good functional properties which can be tailored for use in food and pharmaceutical formulations.
- ItemMineral Composition, Antioxidant Properties, Phytochemical and Anti-nutrient Composition of African Palmyra Palm (Borassus aethiopum) Fruit Flour(American Journal of Food and Nutrition, 2018) Abe-Inge, Vincent; Arthur, Christine; Agbenorhevi, Jacob K.; Kpodo, Fidelis M.; 0000-0002-4898-6046; 0000-0002-2882-3012; 0000-0002-8516-7656; 0000-0002-7949-0502African palmyra palm (Borassus aethiopum) grows widely across Africa. Previous studies indicated its fruit flour has a great potential in food applications. The objective of this work was to investigate the effect of different drying methods on the mineral composition, antioxidant properties, anti-nutrient composition and phytochemical composition of the African palmyra palm (APP) flour. The fresh fruit pulp was obtained, freeze dried, oven dried, solar dried and milled into flour. Phytochemical screening, mineral analysis, anti-nutrient analysis and antioxidant analysis were conducted on the flour obtained according to standard methods. The flour had high total phenols (1518.00 - 3896.71 mg GAE/100g), potassium (237.00 - 276.73 mg/100g), magnesium (211.61 - 293.62 mg/100g) and saponin (36.10 – 55.62 g/100g). The flour samples also had considerable free radical scavenging activities. Phytochemical screening indicated the presence of several phytochemicals including glycosides. Drying had a significant effect on the analysed composition of APP flour.
