Dehydrated Bitter Melon Processing
The species is Momordica charantia L., the bitter melon or bitter gourd, a climbing vine of the gourd family (Cucurbitaceae) grown across Asia, Africa and the Caribbean. Two main types are traded: a long, pale green, warty Chinese type, and a slender, ridged, dark green Indian type. Both belong to one species. A related plant, Momordica cochinchinensis, the gac fruit, is a different species with a red aril and a different use.
The raw material is fresh immature bitter melon. Fruit is picked green and firm, with the white seed core and developing seeds, then washed, sliced, dried in warm air and ground to powder. Drying is the only step that changes the vegetable. The picking stage matters, since ripe fruit turns orange, softens and splits, with red-coated seeds, and is a different material from the green fruit used here.
Bitter melon is a warm-season crop, harvested repeatedly as fruit reaches size. The bitterness is strongest in young fruit and in the white core and seed zone, so powders that include the core are more bitter than powders made from peeled flesh. The cultivar mix and the share of core are not stated, so the powder is described by flavor and shade.
Heat drying does not remove bitterness, because the responsible compounds are stable. What drying changes is the green, vegetal freshness, and the powder reads as drier, more herbal and slightly roasted compared with raw juice.
