Large, spiny green fruit with white, creamy, fibrous pulp. Flavor is a complex blend of strawberry, pineapple, and citrus with a creamy, tropical depth. One cup pulp provides 30% DV vitamin C, 9% DV thiamine B1, 8% DV potassium, 5% DV magnesium, and a range of acetogenins (annonaceous acetogenins) — the pharmacologically active compounds that have generated significant research interest for anti-cancer properties.
Soursop juice at every Caribbean restaurant and market. Frozen soursop pulp at Caribbean, Latin, and West African stores. Fresh fruit at Caribbean and Latin markets in FL, NY, NJ. Goya brand frozen soursop pulp widely available.
Soursop acetogenins (annonaceous acetogenins, primarily annonacin) are the most studied natural compounds for selective cancer cell killing. Laboratory studies have documented acetogenins' activity against multiple cancer cell lines — including breast, colon, prostate, lung, and pancreatic cancer — through mitochondrial complex I inhibition that preferentially kills rapidly dividing cancer cells while sparing normal cells. However, this same complex I inhibition in neurons has raised concerns: high chronic consumption of soursop (fruit or tea) has been associated epidemiologically with atypical Parkinsonism in Guadeloupe — where soursop consumption is extremely high across a lifetime. The APEX position: moderate soursop consumption (the fruit and occasional tea) provides the vitamin C, fiber, and cultural pleasure value safely; very high chronic consumption (multiple daily servings for years) should be avoided, particularly from the leaves and seeds where acetogenin concentration is highest.
Fresh: scoop pulp from skin, remove seeds (seeds are mildly toxic — do not eat). Blend into juice or smoothies. Soursop juice: blend pulp + water + milk/coconut milk + sweetener. Freeze as a sorbet. Soursop tea: dried leaves steeped 10-15 min. Available as frozen pulp at Caribbean markets.
