Abstract
The investigation aimed to analyze the qualitative attributes of ‘Sugar Baby’ variety of watermelon. Ripe fruit consisted of 68.30% flesh, 31.07% rind, and 1.58% seeds. Freshly extracted juice had a pH, total soluble solids, lycopene, ascorbic acid, and total phenolic content of 5.64, 8.90°Bx, 5.23 mg/100 mL juice, 8.22 mg/100 mL juice, and 15.48 mg GAE/100 mL juice, respectively, with a color intensity value of 45.37. Juice had a total aerobic bacteria and yeast & mold counts of 5.69 and 5.68 log cfu/mL, respectively. The predominant sugar and organic acid were fructose (31.10 mg/mL juice) and malic acid (3.38 mg/mL juice). Six key flavor compounds were identified such as 1-Dodecyne; 6-Nonenal (Z); propanoic acid 2-oxo-methyl ester; 2-propanol, 1-methoxy; 5-heptene, 2-one, 6-methyl and hexanal. The rind contains pectin (20.08%) and citrulline (13.36 mg/g and 9.78 mg/g in the skin and peel, respectively). Solvent extraction from dried seeds resulted in 38.66% oil.
