Cacao fermentation. V. Yeasts isolated from cacao beans during the curing process.
Cacao beans must be subjected to fermentation before they are used in making chocolate, and their commercial value is related to a proper procedure. Saccharomyces rosei, Hansenula anomala, Pichia fermentans, Pichia membranaefaciens, and Trichosporon cutaneum were found in fermenting cacao beans. All species isolated during the investigation grew on cacao pulp, but only S. rosei, H. anomala, and...
متن کاملIndependent Origins of Yeast Associated with Coffee and Cacao Fermentation
Modern transportation networks have facilitated the migration and mingling of previously isolated populations of plants, animals, and insects. Human activities can also influence the global distribution of microorganisms. The best-understood example is yeasts associated with winemaking. Humans began making wine in the Middle East over 9,000 years ago [1, 2]. Selecting favorable fermentation pro...

متن کاملChanges in nib acidification and biochemical composition during fermentation of pulp pre-conditioned cocoa (Theobroma cacao) beans
Studies were conducted to establish changes in nib acidification and biochemical composition (sugars concentration, proteins and free fatty acids) during fermentation of pulp pre-conditioned cocoa beans using a 4 x 3 full factorial experimental design with pod storage (0, 3, 7 and 10 days) and fermentation time (0, 3 and 6 days) as the principal factors. Non-volatile (titratable) acidity, pH, s...
متن کاملImpact of fermentation, drying, roasting and Dutch processing on flavan-3-ol stereochemistry in cacao beans and cocoa ingredients
This paper reports a systematic study of the level of flavan-3-ol monomers during typical processing steps as cacao beans are dried, fermented and roasted and the results of Dutch-processing. Methods have been used that resolve the stereoisomers of epicatechin and catechin. In beans harvested from unripe and ripe cacao pods, we find only (-)-epicatechin and (+)-catechin with (-)-epicatechin bei...
