“…this represent a reduction in production cost since a lesser amount of CMC is required to produced gTPS-CMC1. The observation is consistent with previous study on carboxymethylation process using Taguchi technique by Agwamba et al [22] . Figure 3.3 showed that type G and T has no interaction between then when CMC increases from 10 to 50 %.…”

This investigation involves study of independent variable that influences the Young modulus of thermoplastic mango starch (TPS) as dependent response factor. The experiment was design using the Taguchi orthogonal technique with four independent variables; plasticiser type; glycerol (G), and Triethanolamine-(TEA) (T), percentage plasticiser (40 and 120 %), percentage carboxymethyl cellulose-CMC (10 and 50 %), and concentration of HCl (0.05 and 0.15 M). The result of the main effect plots for mean indicated that the gTPS-CMC1 with 268.85a MPa is a better outcome compared to gTPS-CMC3 with 280.31a MPa, since no significance difference was observed due to less composition requirement of CMC for gTPS–CMC1, making it more cost effective to produced with better optimum conditions. The interaction plot of the independent variables showed that for plasticiser types; when glycerol (G) was utilised a higher young modulus is observed than TEA (T) and only interacts with TEA (T) at 0.015 M HCl; 10 % CMC gives a higher response compared to 50 % CMC and showed no interaction even as the other independent variables fluctuates, and similar effect was observed for percentage plasticiser. Study concluded that the predicted mean (young modulus) is substantially consistent with the experimental observation (R2 = 0.6283).

Attempt to save the planet from numerous environmental challenges has been an on-going activity for many decades, through the use of sustainable materials and processes. These have necessitated researches in materials science driven by sustainable chemical approach to derive sustainable materials that do not depend on fossil resources for industrial feedstock, and these materials do not have a negative outcome on the environment. This study investigated the physical and intermolecular interaction of Mango starch derived bioplastic plasticised with sucrose, and reinforced with carboxymethyl cellulose (CMC). Water uptake (WU) were observed to decrease significantly as the molar concentration of HCl or sucrose increases independently, and increase in WU was observation when CMC was increased (p ≤ 0.05). Increasing the molar concentration of HCl or the percentage amount of sucrose as plasticiser has no effect on the oil-uptake (OU), while increasing the percentage of CMC resulted to a decrease, which shows no effect as the CMC amount increases (p > 0.05). Vapour absorption index (VAI) showed a similar trend to WU but significantly, higher outcomes were observed (p ≤ 0.05). The FTIR results also indicate that a physical interaction has occurred between the blends increase in sucrose showed a change in the FTIR peaks especially in the broader peaks observed in the O-H regions of 3500-3200 cm-1 compared to unplasticized native mango starch.

“…12 Deviation in starch constituent and structural features will unavoidably change its fingerprint attributes. 10 The overall physicochemical properties of starch granules will limit the distinct applications of starch-based products in edible and non-edible applications due to the varied impacts of plant nutrients on reserve starch production. In addition, elements like phosphorus, potassium, sodium, calcium, and nitrogen have been shown to have a significant impact on starch constituents, configuration, physicochemical properties, and cooking quality, while the effects of other microelements on starch properties are yet to be fully explored and harnessed.…”

Starches from cassava tubers, sweet potato, and mango seeds were isolated and characterized. The starches' proximate, elemental composition, physicochemical and physical properties, were studied. Cassava tuber yielded 93.45 percent, while Potato and Mango seed yielded 88.65 and 78.45 percent, respectively, in the proximate composition. When compared to cassava at 5.49 and potato starch 5.72, which have a highly acidic pH, mango starch had a neutral pH of 6.9. The moisture content of starch extracted from cassava and mango was significantly closed values at 6.00 and 6.5 percent, respectively, when compared to potato, which had a moisture content of 4.5 percent. Cassava starch (0.0012±0.003, 0.08 ±0.01) had significantly lower protein and nitrogen levels than Potato (0.35±0.00001) and (0.06±0.03), and was significantly lower than Mango starch (0.35±0.01) and (0.06±0.01) (p <0.005). Cassava starch had the highest swelling capacity of 0.940 cm3 compared to 0.285 and 0.250 cm3 for mango and potato, respectively. Cassava and potato starches have significantly higher swelling capacities of 92.00 and 93.00 percent, respectively, than mango starch, which has a swelling capacity of 75.2 percent. Cassava starch had a greater moisture absorption index of 36.00, compared to Potato 24.10 and Mango starch 23.65 percent, which showed no significant difference. Mango starch had significantly higher sodium, potassium, and calcium concentrations than cassava and potato starch, but magnesium and phosphorus concentrations were significantly higher in mango starch than cassava and potato starch. All of the starches have outstanding characteristics and can be used interchangeably, especially in food and pharmaceuticals.
