The toasting variables of three women and the effect on the quality of gari was evaluated. Their toasting time, stirring time, resting time, and manual energy consumption was recorded. The gari toasted by the three women were compared for the chemical composition, pasting properties, functional properties, and particle size distribution. The data obtained were subjected to Analysis of Variance (ANOVA) and means separated using Duncan's multiple range test at p < 0.05 significance. Cassava mash introduced per time ranged between 0.70 and 1.17 kg. The time of introduction of the cassava mash was different for the different women. The toasting time was highest for woman 2 (21.40 min) followed by woman 3 (19.33 min) while woman 1 had the shortest toasting time (17.21 min). The dry matter content of the gari samples ranged from 83.59% (gari from woman 1) to 87.49% (gari from woman 3). The Hydrogen cyanide content of the gari samples ranged from 16.91 to 17.17 mg/kg with the gari toasted by woman 1 having the lowest hydrogen cyanide content. The gari sample toasted by woman 1 had the highest peak viscosity (451.40 RVU). The swelling index of the gari samples toasted by the three women varied significantly (p < 0.05). Woman 1’s gari had the largest particle size (50.66% retained in 850 µm sieve) while woman 2’s gari had the lowest particle size (25.79% retained in 850 µm sieve). The study revealed that the toasting variables of the different women introduced some variations in the particle size, swelling index, and pasting properties of the gari samples.
Practical applications
Data generated from this work will be of use to those working on the fabrication of gari toasting machine. This will help them to understand the gari toasting process. It will also be useful in the standardization of the gari production process.
Orange-fleshed sweet potato (OFSP) is a promising root crop due to its high β-carotene content which could help to reduce vitamin A deficiency (VAD). However, it is a less utilized perishable crop. In order to use OFSP tubers, incorporation with other flours in processing and baked products can be considered. The aim of this study is to determine the functional properties of the composite flour, development of extruded snacks using locally fabricated extruder from flour of different blend ratio of OFSP, YRC, Plantain fortified with moringa leaves powder and to determine the proximate composition of the fresh of orange fleshed sweet potato, yellow root cassava, plantain, the flour and the extruded baked snacks. Uzoaga et al.; JAMB, 20(2): 35-47, 2020; Article no.JAMB.54971 36 Keywords: Functional properties; proximate and extruded baked snacks from orange-fleshed sweet potato; yellow root cassava; plantain fortified with moringa leaves powder.

The sensory characteristic can be quantified and defined by the use of the descriptive profile. A different cultivar of yam can be used for the production of poundo yam. The standard of a product is determined by the evaluation and its acceptability by a taste panelist. Four cultivars of yam; Dioscorea alata, Dioscorea cayenensis, Dioscorea rotundata and Dioscorea bulbifera were sourced and processed into flour. Moringa seed oleifera was defatted and the cake was blended at a different concentration of 5% and 10% with the yam flour. The qualitative phytochemical investigation of the yam flour and Moringa oleifera seed revealed the presence of, alkaloids, steroids, terpenoid oxalate, anthraquinone, phenol, saponins, tannins and flavonoids. Quantitative analysis showed that among the control samples Dioscorea alata (DAC), Dioscorea Dioscorea bulbifera (DBC), cayenensis (DCC) and Dioscorea rotundata (DRC). DRC and DAC have the highest values in the total phenol and total flavonoids. Dioscorea cayenensis recorded the highest value in steroid and saponin content. The flavonoids, steroid and terpenoid were improved by the inclusion of moringa seed meal at 5% and 10%. The result of the sensory analysis revealed that panellist preferred DRC in term of moldability, texture, taste and general acceptability. However, the samples with moringa seed meal at 5% and 10% inclusion compete favourably with the control samples. The inclusion of Moringa oleifera seed meal at 10% improved the pounded yam and was more accepted than the 5% in term of general acceptability.
