Breadfruit is a high-carbohydrate fruit that grows in abundance in tropical nations that struggle with hunger and poverty. Breadfruit has been long recognized for its potential to alleviate hunger in countries like Haiti, but there’s just one problem: fresh breadfruit rots in 48 hours.
But if poor communities were able to make flour out of breadfruit, locally produced breadfruit flour could replace expensive imported cereals and increase food security.
Compatible Technology International (CTI), with help from a team of engineers, researchers and breadfruit experts, is developing a set of tools that will allow villagers to process breadfruit into shelf-stable flour.
CTI has designed a manually-operated shredder that shreds breadfruit into small strips that are optimally shaped for quick drying. Engineers at CTI and the University of Saint Thomas (UST) reached the current shredder design after testing other concepts with communities in Haiti.
After they are shredded, the breadfruit strips must be dried quickly to prevent spoiling. To source the best technologies for this crucial step, UST recently organized and judged a contest challenging teams to develop a simple, effective and affordable breadfruit drying structure.
The first place winner of the contest is a team of long-time CTI volunteers, and second place is a team from the University of California, Davis. In March, both teams will travel to Hawaii to present their designs at the Breadfruit Institute, a division of the National Tropical Botanical Garden.
Once dried, breadfruit strips can easily be ground into flour by villagers using CTI’s grinder. The breadfruit processing system will go through rigorous tests at the Breadfruit Institute before being deployed in the Caribbean.
Breadfruit flour could be an important microenterprise opportunity and an untapped source of nutrition for food insecure communities. With your help, we can get these and other innovations into the hands of the communities that need them.
