Caribbean Knowledge Exchange

In August 2026, Hawaiʻi ʻUlu Cooperative participated in a knowledge exchange with two breadfruit manufacturers in Puerto Rico and one in St. Croix, U.S. Virgin Islands. Facility and farm visits showcased the many common challenges and opportunities shared by processors, producers and farmer organizations across the Pacific and Caribbean regions.

Breadfruit is a tropical crop that does not grow in the Continental U.S., outside of a few limited plantings in southern Florida. Therefore, Hawaiʻi, Puerto Rico and St. Croix are among the only U.S. territories where breadfruit can be grown commercially. The other territories include American Samoa, Guam and the Northern Mariana Islands in the Pacific, which have an arguably less developed commercial breadfruit industry than the Caribbean, hence the value of this particular knowledge exchange.

In addition to learning about each organizationʻs operations and sharing common experiences and challenges, the partners exchanged information about local crop supply, varieties, production methods, propagation, fruit pricing and value chain economics, product development, equipment, food safety, marketing tactics, certifications, and future plans and goals. Beyond advancing the specific technical objectives outlined above, an overarching purpose of this exchange is to build relationships between Hawaiʻi and Caribbean breadfruit manufacturers with the aim of strengthening each regionʻs breadfruit industry and supporting its small-scale farmers. 

Introduction of Breadfruit

Breadfruit (ʻulu in Hawaiian) is a traditional Pacific crop that was introduced to Hawaiʻi about 1,000 years ago by Polynesian voyagers, the islands’ first human inhabitants. There it provided an important source of nutritious staple food for the growing population and contributed to the development of a complex and highly sophisticated agricultural society across the islands. Meanwhile, breadfruit was brought to the Caribbean by British navigators in the late 1700s to feed the slavetrade upon which various European colonizers built sugarcane plantations. Originally introduced to St Vincent in the Lesser Antilles and then Jamaica in the Greater Antilles, once breadfruit was in the Caribbean it spread from island to island. Today, breadfruit has become naturalized across the region, and is a popular locally grown staple alongside plantains, cassava, and other starches. 

Breadfruit Culture in the Caribbean

Given its original connection to slavery, it is not surprising that in some Caribbean countries, breadfruit was not initially embraced by local residents.  However, in Puerto Rico, people fell in love with breadfruit from the start. Soon after the crop’s introduction, many homes had their own breadfruit tree, known as panapen, mapen or pana in different parts of the country (pan means bread in Spanish). Communities relied on these trees and other viandas (traditional starches like cassava) for sustenance. 

Interestingly, pana in Puerto Rico has also come to mean “close friend”, which some say has to do with the tradition of gifting breadfruit to close friends when visiting them (here is a “pana for my pana”, or a “breadfruit for my friend”). Breadfruit has also long been recognized as a nutritious and filling staple food in Puerto Rico, with another phrase “chuleto de gancho” referring to breadfruit as “porkchop of the branch,” because it can be eaten as a main course. 

While Puerto Rico is still a colony of the U.S., its Boricua people (from Boriken – the indigenous Taino name for Puerto Rico) celebrate their successful resistance to colonization of culture since the American invasion of 1898. This includes language, customs, and music, but also food, including pana. Supposedly, after the American takeover from Spain following the Spanish-American War, Americans offered to pay Puerto Ricans to cut down their breadfruit trees in order to replace pana with U.S.-grown potatoes. This was vehemently rejected and Puerto Ricans protected their breadfruit trees, or in some cases, took the money knowing that breadfruit regenerates through the root system and would regrow within a few years. Some Puerto Ricans even regard breadfruit as a sacred tree, with one local likening it to the weirwood of Westeros in Game of Thrones.

Breadfruit Cuisine

In Hawaiʻi, Puerto Rico and St. Croix, traditional breadfruit preparations were simple. In Hawaiʻi, ʻulu was cooked in an imu (underground oven) or roasted over the fire, and the chunks were flavored with sea salt, coconut milk or pounded into poi and eaten with fish or meat. After the introduction of western cooking techniques, ʻulu was also baked, steamed or boiled, but still generally eaten as a relatively plain starch alongside the main course. In Puerto Rico and St. Croix, traditional preparations include boiled or roasted breadfruit served with salted fish or meat, perhaps drizzled with olive oil and salt. 

Today, however, in all three territories, breadfruit is seeing a culinary renaissance. In Puerto Rico, relatively recent innovations feature pana instead of plantains in traditional dishes like tostones, mofongo, rellenos, and pastelles, as well as new creations such as pastelon (similar to shepardʻs pie), gnocchi, and more. A new breadfruit restaurant called Panapen & Co. has even been established in Caguas, about 30 minutes from San Juan, featuring pana in every dish! In St. Croix, beyond vodka, breadfruit is turned into mash, croutons, and a creamy drink called Sea Moss.

Processing Models & Case Studies

Frozen Pana Processing: Wonderen Foods / Panawest

Located in Mayaguez, Puerto Rico, Wonderen Foods was founded by Juan Carlos Rodriguez to supply value-added frozen breadfruit products.

  • Outputs: Processes approximately 30,000 pounds of raw fruit per year sourced from 12 local farms.

  • Manufacturing Line: Features semi-automated peeling, slicing, blanching, flash-frying, vacuum-sealing, and metal detection.

  • Key Takeaway: Semi-automation allows small-scale facilities to maintain strict quality control and extended shelf life without requiring multi-million-dollar processing lines.

Flour & Dry Processing: Amasar

Operating out of a 2,000-square-foot facility in Jayuya, Puerto Rico, Amasar was established by Marisol Villalobos and Jesus Martes.

  • Outputs: Handles roughly 100,000 pounds of fruit annually from a network of 30 growers.

  • Operational Workflow: Incoming fruit undergoes washing, hand-chopping, mechanical shredding, 14-hour cabinet drying at regulated temperatures, hammermilling, and clean-room packaging.

  • Certifications: Holds Certified B Corporation status, Certified Gluten-Free, Non-GMO Project Verified, and Caribbean Kosher certifications to access high-value specialty markets.

  • Secondary Agritourism: Hosts weekly factory and farm tours to cultivate consumer education and direct-to-consumer sales.

Spirit Distillation: Mutiny Island Vodka

Based in St. Croix (USVI), Mutiny Island Vodka utilizes processed breadfruit rather than fresh fruit as its primary fermentable substrate.

  • Supply Sourcing: Currently utilizes ~21,000 pounds of processed breadfruit annually. While most of this is currently sourced from outside the region, the company is interested in partnering with local organizations to increase local sourcing and processing.

  • Future Goals: Mutiny would like to source more of its processed breadfruit from the Caribbean region, but price and volume are concerns. It is currently exploring options to support a pilot-scale operation on St. Croix to create a small, limited release vodka that is entirely local.

Comparative Regional Economics

Economic realities shape processing feasibility and fruit pay-prices for farmers across territories:

Economic Parameter HUC Puerto Rico St. Croix (USVI)
Minimum Wage $16.00 / hr $10.50 / hr ($7.25 / hr agri.) $12.00 / hr
Electricity Cost 42 – 52 ¢ / kWh 21 – 30 ¢ / kWh 39 – 47 ¢ / kWh
Grade A Raw Fruit Price ~$1.40 / lb $0.33 – $0.35 / lb N/A
Retail Flour Price ~$10.00 / lb ~$4.00 / lb ($11.49 / 24 oz) $1/lb for St Croix (wholesale)
Food Import Reliance ~85% ~85% >95%

Agronomic & Pest Management Warnings

The exchange highlighted severe orchard health threats that require vigilant biosecurity measures in Hawaiʻi:

  • Mango Stem Borer Beetle (St. Croix): A major pest infestation has devastated breadfruit orchards in St. Croix, causing an estimated 80% tree loss at Ridge to Reef Farm.

  • The beetle cuts a strip in the bark to lay her eggs, and eats all parts of the tree fruit, bark leaves, and even branch tips. The first sign of infestation is usually along the midrib of the leaf, which the beetle chews and ultimately punctures, causing the leaf to bend over in the middle while still on the tree.
  • Currently, the Mango Stem Borer has not been established within the Hawaiian Islands. Likely vectors of introduction could include untreated wooden crates like pallets, imported nursery plants, untreated raw wood, hidden on cargo, or any agricultural plants. This concerning pest illustrates the importance of maintaining proper import regulations for our community.
  • Animal Damage & Land Access: St. Croix producers report widespread bark-chewing damage from wild deer populations. In Puerto Rico, high agricultural land prices ($25,000/acre post-Hurricane Maria), farmer outmigration, and rising synthetic fertilizer costs restrict orchard expansion.

Summary & Strategic Next Steps 

While Hawaiʻi, Puerto Rico and St. Croix have much in common, the territories also face some different challenges and opportunities. Hawaiʻi deals with much higher costs of production, particularly for labor and fresh crops, as well as energy and land. All three territories are disadvantaged by the early 20th century Jones Act, which mandates that all goods shipped between U.S. ports must be carried on vessels that are built in the U.S., flagged in the U.S., and crewed by U.S. – significantly inflating shipping costs for the plethora of goods that are imported. 

As a result, Hawaiʻi fruit prices are about four times as high as they are in Puerto Rico ($1.40/lb vs. $0.33/lb for Grade A fruit), and finished product prices are, too. Amasar currently sells its flour for about $4/lb while Hawaiʻi ʻUlu Co-op does for $10/lb, and even this is with a razor thin margin. 

At the same time, many Hawaiʻi consumers are willing to pay a premium for local products, especially those made with breadfruit, which is relatively less accessible to the average consumer than it is in Puerto Rico. A 2019 study by Needham and Lincoln found that 57% of Hawaii consumers eat breadfruit only three times per year.
