The main energy supply in Ghana is based on biomass: firewood and charcoal (64%), which are burnt openly for cook and heat energy. This practice has led to deforestation and biomass shortage. Besides the energy challenge, Ghana faces declining of soil fertility due to continuous cultivation and rapid mineralization of its soil organic matter, both problems being considered as major causes of food insecurity and poverty in the country. We studied the carbonization of rice husks and corn stalks - the two main available sources of waste biomass in the studied regions - and qualifying these products as fuel and biochar. We pyrolysed both feedstocks at three different temperatures - 350, 450 and 550 °C - and measured their solid yields; ash and volatile contents; C, H, N percentages; pH and electro-conductivities and; nutrients contents in all samples. We also compared the thermogravimetric behavior and NMR profiles of these samples. Corn stalks showed better potential to be used as a fuel. Both feedstocks have potential to be used as biochar but with varied composition. |

Brazilian Cerrado wheat has emerged as an alternative to expand a new agricultural frontier in tropical areas. In this study, technological quality of 34 samples grown in five locations situated in the Cerrado Mineiro was evaluated in terms of their grain, flour, and starch properties. Damaged starch was positively (p < .05) correlated with Single Kernel Characterization System parameters (r = 0.578) and pasting properties (r = 0.761), and negatively (p < .05) correlated with enthalpy (r = −0.400) and relative crystallinity (r = −0.379). The irrigation system strongly influenced the starch characteristics, rheological, and pasting properties. Piumhi location showed the highest mean of resistant starch (0.80 g/100g), bringing an interesting prebiotic appeal to these samples. Gluten index (mean = 90.6) and damaged starch (mean = 5.0%) values showed that genotypes present suitable standards for bakery products. This pioneering study highlights promising agronomic materials for cultivation in the Brazilian Cerrado region, which has great potential to produce tropical wheat. Practical applications Wheat is the second most significant staple grain after maize, constituting a strategic role in food security to the world economy. In Brazil, more than 90% of wheat is grown in traditional areas that include subtropical climates. In this scenario, Brazilian Cerrado has been standing out as a potential region for wheat cultivation to produce improver wheat class that is the main consumer-driven market. Wheat culture has been adapted under Cerrado conditions after massive investments regarding genetic improvement and integrated soil?water? nutrient? plant practices that allow high grain productivity. Thus, the characterization of wheat grain associated with flour rheological evaluation and starch profile is effective in predicting processing behavior and applicability in different bakery products. The results showed that irrigation system strongly influenced the rheological and pasting properties of starch. These samples showed suitable contents of dry gluten 11%?14%) and damaged starch (4.5%) for bakery products development.
