15 of 86 compounds on file carry a paper the library can cite.

• acetaldehydearomaaldehydereads as pungent, fruity odor (PubChem)Measured in 18 of 338 ingredients.cite

  4255.2 ug/kg in flesh, the largest single value in the whole table; the paper's Results call acetaldehyde one of 'the 11 most dominant volatile compounds (at least 1% peak area)' at 3.9-17.0% of total volatiles — Du et al. 2022, Molecules (Table 2 (Volatile compounds in watermelon rind-flesh blends, ug/kg), row 'Acetaldehyde' (LRI 672), column '0% Rind' — flesh only)
• propanalaromaaldehydereads as characteristic odor similar to acetaldehyde (PubChem)Measured in 11 of 338 ingredients.cite

  84.9 ug/kg in flesh, against 1.4 ug/kg in the rind-only sample — a 60-fold difference, the sharpest flesh/rind contrast of any compound in the table — Du et al. 2022, Molecules (Table 2, row 'Propanal' (LRI 794), column '0% Rind')
• hexanalaromaaldehydereads as sharp, aldehyde odor (PubChem)Measured in 85 of 338 ingredients.cite

  identified in fresh watermelon juice by GC-O-MS on both DB-Wax and DB-5 columns — Yang et al. 2020, Foods (Table 2 (Flavor compounds identified by GC-O-MS in fresh watermelon (FW) and thermally treated watermelon juice (TW)), aldehyde row 2 'hexanal')
• 2-methylbutyraldehydearomaaldehydeMeasured in 11 of 338 ingredients.cite

  identified in fresh watermelon juice — Yang et al. 2020, Foods (Table 2, aldehyde row 1 '2-methylbutanal')
• 1-hexanolaromaalcoholreads as fatty, fruity (PubChem)Measured in 48 of 338 ingredients.cite

  flavour dilution factor 81 in fresh watermelon juice; the paper later treats it as an off-flavour contributor in the heated juice — Yang et al. 2020, Foods (Table 2, alcohol row 27 'hexanol', FD column for fresh watermelon (FW))
• 6-methyl-5-hepten-2-onearomaketonereads as fruity taste (PubChem)Measured in 15 of 338 ingredients.cite

  identified in fresh watermelon juice (FW) — Yang et al. 2020, Foods (Table 2, ketone row 38 '6-methyl-5-hepten-2-one')
• nonanalaromaaldehydereads as orange-rose odor (PubChem)Measured in 59 of 338 ingredients.cite

  identified in fresh watermelon juice; the paper's introduction names nonanal first in its list of the C6 and C9 compounds that carry watermelon juice flavour — Yang et al. 2020, Foods (Table 2, aldehyde row 8 'nonanal')
• (E,Z)-2,6-nonadienalaromaaldehydeMeasured in 8 of 338 ingredients.cite

  flavour dilution factor >81 in FRESH watermelon juice — the highest FD of any aroma-active compound the paper found, tied with its value in the thermally treated juice — Yang et al. 2020, Foods (Table 2, aldehyde row 14 '(E,Z)-2,6-nonadienal', FD column for fresh watermelon (FW))
• cis-3-hexen-1-olaromaalcoholreads as powerful grassy-green odor (PubChem)Measured in 21 of 338 ingredients.cite

  identified in fresh watermelon juice — Yang et al. 2020, Foods (Table 2, alcohol row 28 '(Z)-3-hexenol')
• 2-HexenalaromaaldehydeMeasured in 31 of 338 ingredients.cite

  identified in fresh watermelon juice — Yang et al. 2020, Foods (Table 2, aldehyde row 5 '(E)-2-hexenal #')
• 2-OctenalaromaaldehydeMeasured in 23 of 338 ingredients.cite

  flavour dilution factor 27 in fresh watermelon juice, rising to >81 after heating — one of the seven compounds the paper's omission experiments confirm as off-flavour drivers in the heated juice — Yang et al. 2020, Foods (Table 2, aldehyde row 9 '(E)-2-octenal *', FD column for fresh watermelon (FW))
• 2-NonenalaromaaldehydeMeasured in 20 of 338 ingredients.cite

  flavour dilution factor 27 in fresh watermelon juice — Yang et al. 2020, Foods (Table 2, aldehyde row 13 '(E)-2-nonenal', FD column for fresh watermelon (FW))
