When ripe, the skin is yellowish-brown to light brown, slightly rough, relatively thin, and easy to peel.
The flesh is translucent white, relatively thick and juicy, surrounding a black seed. Edible flesh proportion and seed size may vary among individual fruits.
Properly ripe fruit should have dry and intact skin without cracks or juice leakage. The stem should remain relatively fresh, and the fruit should show no signs of deterioration.
Acceptable raw material should be fresh, firm, and intact, free from bruising, decay, mold, fermentation, or abnormal odors. The flesh should not be excessively soft, watery, or abnormally discolored.
