| Abstract | The cocoa (Theobroma cacao) fermentation was carried outusing starter consortia of Saccharomyces cerevisiae, Lactobacillusplantarum, and Acetobacter aceti with 10% inoculum. The fermented beans were soaked with sterile water (1:3 wt/v) for the duration of 1, 3, and 5 h. The treated beans were dried to the moisture content of 7 ± 1%. The samples were then roasted, ground and subjected to steam distillation. The volatiles were extracted and identified using GC-MS. The samples soaked for 1h scored 100% cut score along with 0.85% fermentation index. The volatile and non-volatiles were associated with beans treated in water after fermentation. Volatile compounds were classified as esters, alcohols, acids, aldehydes, ketones, pyrazines, hydroperoxides, and hydrocarbons. Most of the oxygenated aliphatic compounds and aromatics were potentially derived via an acetic acid and shikimic acid pathways, respectively. Untreated cocoa beans contained 12 sesquiterpene hydrocarbons potentially derived through the mevalonic acid pathway and contributed to harsh notes. Also, these metabolites were completely absent in the treated samples indicating depletion while soaking. Thus, the treated samples (1 h) had enhanced quality with high flavor notes with 8.5 rating on sensory evaluation. Thus, these soaking treatments with fermentation lead to improvement of flavor profiles which confers improved cocoa quality. |
