          <dc:description>The fine-flavor cocoa
agro-industrial chain generates on-farm side
streams with distinct origins and processing histories, yet their
compositional diversity remains insufficiently characterized under
industrial conditions. Here, we performed an integrated compositional
and metabolomic characterization of cocoa pod husk, cocoa pulp juice,
and cocoa syrup generated within a large-scale monoclonal fermentation
system (Luker 40; ∼500 kg per fermentation box) operating within
an industrial fine-flavor cocoa production system exceeding 73,000
tons annually. Metabolomic characterization was performed using three
independent industrial production batches as biological replicates
(n = 3), whereas proximate and mineral analyses were performed on
composite samples prepared from the three batches. Mineral composition
showed the largest relative differences among matrices, with cocoa
syrup reaching an ash content approximately 12 times that of cocoa
pulp juice. Complementary LC-MS and GC-MS analyses enabled the annotation
of 82 metabolites (46 by LC-MS and 36 by GC-MS), revealing distinct
matrix-resolved profiles, including caffeic acid, epicatechin, and
procyanidin B1 in cocoa pod husk; glutamine, glutathione, and indole
carboxaldehyde in cocoa pulp juice; and N-(deoxyfructosyl) amino acid
derivatives in cocoa syrup. To our knowledge, this is the first joint
compositional and metabolomic description of a thermally concentrated,
fermentation-derived cocoa syrup together with prefermentation cocoa
pulp juice recovered from the same production batches. These results
provide a compositional baseline for subsequent targeted quantification,
extraction/recovery, and functional validation, supporting the rational
prioritization of cocoa side streams and derived products for future
valorization studies.</dc:description>
