Saint Vincent Arrowroot Starch Processing

Arrowroot

The harvesting and hand-and-machine processing of arrowroot (Maranta arundinacea) rhizomes into one of the purest natural starches in the world, a craft first practiced by Saint Vincent's indigenous peoples and later developed into a dominant national export industry that, at its 1987 peak, accounted for 95% of the entire world's commercial arrowroot starch supply and, at its historical height, nearly 50% of Saint Vincent's total foreign exchange earnings. The industry's last bastion of traditional processing, the Owia Arrowroot Factory, was tragically destroyed by the eruption of the La Soufrière volcano in April 2021 — one of the most specific and dramatic single-event craft-endangerment episodes documented anywhere in this archive. In 2020, prior to the eruption, the Saint Vincent government had already secured a US$1.03 million grant from India via the United Nations Industrial Development Organization (UNIDO) to support the industry's revival.

Geographic Center
Northeastern Saint Vincent, where arrowroot production was historically concentrated (including Owia); production expanded regionally in the 1930s and again shifted north in the 1980s–90s as banana cultivation displaced arrowroot from other areas
Community / Ethnic Group
Vincentian community, with the crop's cultivation originating among the island's Indigenous peoples
Estimated Origin
Arrowroot was traditionally grown by Saint Vincent's Indigenous peoples before European contact; it developed into a major commercial export crop from the colonial era onward, sharing similar cultivation requirements with sugarcane, and the industry's documented performance spans major fluctuations from the 1930s through 2010, with Saint Vincent becoming the world's dominant commercial producer by the late 20th century
Cultural Function
Historically central to Vincentian national economic identity and foreign-exchange earnings; arrowroot remains a documented culinary staple, used in traditional dishes including madongo/madungo dumplings (arrowroot, nutmeg, and coconut) and arrowroot cakes and puddings, described as showcasing 'the island's historically important arrowroot crop, once a major export'
Primary Materials
Arrowroot (Maranta arundinacea) rhizomes, containing approximately 12–20% starch by dry weight, of which 17–18% is typically extractable
Primary Tools
Rasping/crushing equipment for pulping rhizomes; washing screens for starch-fiber separation; centrifuge or filtration equipment; drying and grinding equipment for finishing the powder
Process Overview
Arrowroot rhizomes are hand-harvested (or, increasingly, mechanically harvested) from Vincentian farms, then rapidly transported to a processing factory where they are washed, cut, rasped into pulp, macerated, washed across screens to separate starch from fiber, centrifuged or filtered, dried, and ground into finished powder for grading, blending, and export — a process that must occur within days of harvest due to the tubers' rapid post-harvest deterioration.
Traditional Applications
A major commodity export crop and a domestic culinary staple, used in traditional dishes such as madongo/madungo dumplings and arrowroot cakes and puddings
Contemporary Applications
Renewed commercial interest driven by rising global demand for gluten-free food products, positioning Saint Vincent — as a historical world leader — for a potential industry revival, per 2025 academic analysis; continued domestic culinary use
Notable Practitioners
Named individual contemporary practitioners were not identified in available sources at time of writing; the industry is documented at an institutional/community scale via factory workers, farmers, and the St Vincent and the Grenadines Arrowroot Industry Association
