    (Cogent Food & Agriculture, 2020) Abe-Inge, Vincent; Asaam, Esumaba Serwaa; Agbenorhevi, Jacob K.; , Bawa, Nadratu Musah; Kpodo, Fidelis M.; 0000-0002-4898-6046; 0000-0002-8516-7656; 0000-0002-3861-779X; 0000-0002-7949-0502
    Borassus aethiopum (African palmyra palm (APP)) fruit is an underutilized tropical fruit but has potential food applications. In the present work, the suitability of APP fruit–wheat composite flour in the development of noodles was investigated. The fresh APP fruit pulp was separated, oven-dried at 60°C and milled into flour. The obtained flour was mixed with commercial wheat flour to obtain three composite flours with 5%, 10% and 15% of APP fruit flour. The functional properties and proximate composition of the composite flours were determined. The cooking properties and consumer preference of the noodles developed were also evaluated. The cooking yield, water uptake and gruel solid loss ranged from 259.81% to 300.97%, 159.81% to 200.97% and 11.52% to 17.11%, respectively. The water absorption capacities, swelling power and the solubility indices of the flours ranged from 197.10% to 492.66%, 621.99% to 734.91% and 4.53 to 26.48%, respectively. On the 7-point hedonic scale, the flavour, smell, colour and overall accept ability ranged between 4.2 and 5.3, 4.8 and 5.65, 4.05 and 5.3 and 4.10 and 5.03, respectively. The inclusion of APP fruit flour at 5% level yielded noodles with enhanced nutritional quality and highest overall consumer acceptability.

    Effect of different drying techniques on quality characteristics of African palmyra palm (Borassus aethiopum) fruit flour
    (Food Research, 2018-08) Abe-Inge, Vincent; Agbenorhevi, Jacob K.; Kpodo, Fidelis M.; Adzinyo, O. A.; 0000-0002-4898-6046; 0000-0002-8516-7656; 0000-0002-7949-0502
    African palmyra palm (Borassus aethiopum Mart.) fruits are underutilized in Sub-Saharan Africa. The objective of this study was to produce flour from the African palmyra palm (APP) fruit pulp and evaluate the effect of different drying methods on the quality characteristics of the flour. The fresh pulp was oven, solar, and freeze-dried. Proximate, physicochemical and functional properties of the flours were determined. The flours had high amount of crude fibre (14.04-19.52%), carbohydrates (64.56-73.60%), energy (281.92 - 73.60 kCal/ 100g), relatively high water absorption capacity (307.18-517.66%), swelling power (433.0-556.92%), oil absorption capacity (83.48-164.38%) and good flowability (Hausner Ratios below 1.4 and Carr’s Indices below 23%). The present findings show that APP flour could be used as a potential ingredient in various food products such as pasta, puddings, cakes, biscuits, bread, crackers and doughnuts

    Effect of okra pectin on the quality and consumer acceptability of tigernut milk and fried yam
    (Cogent Food & Agriculture, 2020) Abe-Inge, Vincent; Agbenorhevi, Jacob K.; Katamani, Grace D.; Ntim-Addae, Samuella B.; Kpodo, Fidelis M.; 0000-0002-8516-7656; 0000-0002-4898-6046; 0000-0002-7949-0502
    The objective of this study was to investigate the effect of okra pectin as a stabilizer and a texturizer on the quality and consumer acceptability of tigernut milk and fried yam, respectively. Okra pectin concentrations 0% (control), 0.2%, 0.4% and 0.6% were used in the preparation of tigernut milk as well as to pretreat yam slices before deep frying. The viscosity and microbial quality of the tigernut milk samples were evaluated, whilst the moisture content, oil uptake and colour of fried yam were also determined. Consumer acceptability test was conducted on both the tigernut milk and fried yam using 50 semi-trained panelists. The viscosity of the tigernut milk samples which ranged from 4.67 cP to 10.50 cP increased with increasing concentrations of okra pectin. The microbial load of all tigernut milk samples were within the acceptable limits. With the exception of sample appear ance, okra pectin also had no significant effect (p > 0.05) on the sensory quality of tigernut milk. On the other hand, okra pectin treatment in the fried yam samples resulted in significantly different moisture (54.33–56.71%), oil uptake/fat content (4.00–5.50%) and colour (L*a*b*) values. Results showed that okra pectin had no significant effect (p > 0.05) on all sensory quality parameters of fried yam samples though 0.2% okra pectin treated yam had the highest mean overall acceptability. The findings suggest that treatment with okra pectin can be exploited to make appreciable impact on the quality and consumer acceptability of fried yam.

    Mineral 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; 0000-0002-7949-0502
    African 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.

B.; Oduro, Ibok N.; Abe-Inge, Vincent; Datsomor, Delight N.; Atongo, Juliana; Obeng, Beatrice; 0000-0002-8516-7656; 0000-0002-7949-0502; 0000-0003-2268-6122; 0000-0003-3731-2684; 0000-0002-4898-6046; 0009-0002-2835-8015
    Okra (Abelmoschus esculentus) is an economically important crop in sub-Saharan Africa. The vegetable is of major technological interest in food and medicinal applications. A survey was conducted by administering structured questionnaires (1560) in major okra-producing regions in Ghana to determine the level of okra utilization and nutritional and medicinal attributes of the crop. The okra pectin yield and intrinsic viscosity at different maturity stages were also investigated. Isolation of okra pectin from the pods at different harvest maturity was performed by aqueous extraction at pH 6.0. The intrinsic viscosity [η] of the okra pectin solutions was deter mined at 20°C using Ubbelohde capillary viscometer. The survey showed that okra is well known (96.9%) across the country among the various ethnic groups. The majority (94.7%) of the respondents use okra as food, whereas few utilized the crop as medicine (22.1%) and for other applications (9.6%). The respondents widely used okra in the form of soup (73.1%) and stew (68.7%) consumed popularly with banku (81.3%) and tuo zaafi (38.8%). The majority of respondents (65.2%) showed interest in the development of new products from okra. Highest pectin yield was obtained for intermediate matured fruits, followed by that of immature fruits and lowest for overgrown fruits. The intrinsic viscosity value, however, was highest for immature fruits. The study showed that okra is mainly used as food among various ethnic groups and that it is important to identify the most appropriate stage of development to harvest the okra fruit. This knowledge would enhance the potential of okra for specific use or functionality.
