The determination of nutritional composition and bacterial communities in dawadawa was conducted using standard spectrometric methods and 16S RNA sequencing, respectively. Proximate analysis revealed significant variations in fat (17.45%-27.70%), protein (36.12%-50.00%), and fiber (6.39%-7.32%) across different locations, with Sunyani samples exhibiting the highest protein content. Mineral analysis showed notable differences in iron (79.60-135.00 mg/kg), zinc (37.75-91.77 mg/kg), and calcium (0.73%-1.61%), suggesting potential nutritional benefits. Microbial profiling using 16S rRNA sequencing identified <i>Bacillus</i>, <i>Staphylococcus</i>, <i>Streptococcus</i>, and <i>Lactobacillus</i> as predominant genera, with <i>Bacillus subtilis</i> being the most abundant species. Domestic dawadawa exhibited higher microbial diversity compared to commercial samples, with greater amplicon sequence variant (ASV) richness. Functional bacterial groups correlated with enhanced protein and mineral bioavailability, supporting dawadawa's role as a probiotic and functional food.

The fleshy pulp of the <i>U. kirkiana</i> fruit is eaten fresh or processed into a variety of products, including juices, squashes, wines, sweet beer, porridge, jams and cakes. However, the commercialisation of the fruit wines still remains a challenge due to a lack of consistency in product quality. The purpose of this study was to use response surface methodology (RSM) to optimise the fermentation of wild loquat (<i>U. kirkiana</i>) fruit wine. A study to investigate the relative contributions of two predictor factors (Brix value and yeast quantity) to the quality of wine was conducted using RSM. Design Expert 7 was used for a central composite design (CCD). Thirteen (13) runs of wine were produced as outlined in the CCD for the independent variables. The responses measured included alcohol by volume (ABV percentage), density, real extract (Er), original extract, Plato, real degree of fermentation (RDF), pH, calories and colour. Overall, Brix had the greatest influence on responses, showing substantial correlations whether they were positive or negative. In contrast, yeast and responses tended to have weaker correlations, with the exception of pH, where the converse was true for both independent components. The optimum values of Brix and yeast for the fermentation of <i>U. kirkiana</i> wine were found to be 24.44°Bx and 1 g, respectively. The predicted values for the responses are 11.83% (ABV), 1.00539 g/cm³ (density), 75% (RDF), 5.53 EBC (European Brewery Convention) colour, 350.998 kJ/100 mL or 87 kcal and pH of 3.5. The developed models could predict the quality of wine developed from wild loquat fruit.
