Both the Dehytray and Dehymeleon technologies spun out from a United States Agency for International Development (USAID)-supported effort called Feed the Future Innovation Lab for Food Processing and Post-Harvest Handling,” said Klein Ileleji, co-founder and CEO/chief technology officer of JUA Technologies. “It was a multi-institutional effort led by Purdue University to reduce postharvest loss, promote economic growth, improve nutrition and enhance food security in Feed the Future target countries."

Food Processing and Post-Harvest Handling Innovation Lab (FPIL) receives no cost extension to finalize comprehensive project
June 15, 2022
The FPIL recently received United States Agency for International Development (USAID) approval for a no cost extension. After eight years of investment and effort, the extended timeline of one year (May 2023) will allow FPIL to bring capstone research, extension and scale-up activities to sustainable ends.

Providing Cost-Effective Ways to Prevent Aflatoxin Contamination
September 16, 2020
FPIL researchers have studied cost-effective ways to prevent or limit aflatoxin contamination of key crops for rural subsistence households in Sub-Saharan Africa. In collaboration with Istitut Sénégalais de Recherches Agricoles (ISRA), the premier agricultural research institution in Senegal, the research team set up a randomized intervention in the Department of Vélingara in southern Senegal.

Madame Mbacke Provides Opportunity and Empowerment for Senegalese Women
April 30, 2020
In Senegal, an instant flour business uses technology provided through the Food Processing Innovation Lab (FPIL) to provide employment to 1,147 Senegalese women. This offers them a source of income, empowerment and independence. The business owner, Madame Astou Gaye Mbacke first partnered with the FPIL in 2016. Since then this partnership has led to her business, the Touba Darou Salam Cereal Processing Unit, gaining a food extruder giving the facility the technical capacity to develop instant enriched flours.

Providing sustainable post-harvest solutions for sub-Saharan Africa
November 25, 2020
Food security does not end at harvest. Despite advances in agricultural productivity, hunger, malnutrition and poverty remain stubbornly persistent in many developing countries. One contributing factor is that more than one-third of the food produced worldwide is lost or wasted after harvest.

Saving for the Future
November 20, 2017
It’s impossible to measure the full impact of Madame Astou Gaye Mbacke’s entrepreneurship on the people of Senegal—and it all grew from small golden grains of millet. Her facility processes cereal-based products from grains grown by Senegalese farmers, including signature products of millet grain mixed with mango, baobab, or other local fruits and run through an extruder. The result: precooked pellets that are ground into a fortified flour, the key ingredient of porridge. Thanks to the extruder, the preparation of porridge is reduced from hours to minutes. Just add hot water, and an entire family is fed.

In partnership with the Feed the Future Innovation Lab for Food Processing and Post-Harvest Handling, Madame Astou Gaye Mbacke's facility now has a food extruder, which gives it the technological capacity to turn cereal grains into instant enriched flour.

Purdue hosting international post-harvest loss reduction meeting
January 8, 2016
This week, Purdue is hosting the initial technical meeting for APHLIS+, a project for the African Post Harvest Loss Information System. Purdue was chosen to host the meeting due to its recognized strength and experience in the area of post-harvest loss reduction and value-chain enhancement in developing countries, says Corinne Alexander, professor of agricultural economics.

Researchers Discover Impact of Modern Storage Technology on Adoption of Improved Maize Varieties in Southern Africa
June 19, 2015
It is widely known by farmers in Southern Africa that improved dent varieties of maize are higher yielding than traditional flint varieties. However, farmers also know that improved dent varieties are more susceptible to insect pests in storage than traditional flint varieties due to their open husks and softer kernels. Farmers face a rational trade-off at planting time. They must choose between a higher yielding but more pest susceptible dent variety, or a lower yielding but more pest resistant traditional flint variety. Feed the Future Food Processing and Post-Harvest Handling Innovation Lab, (FPL) researcher Dr. Jacob Ricker-Gilbert, Assistant Professor in Agricultural Economics at Purdue University and his former graduate student Michael Jones recently published an article in Food Policy that estimates how smallholder farmers in sub-Saharan Africa make this decision.

FPL Researchers Gear Up to Collect Weather Data to Evaluate Post-Harvest Operations in Senegal and Kenya
June 19, 2015
The weather plays a crucial role in crop post-harvest operations such as when to harvest, harvest duration, drying and storage. When grain becomes physiologically mature to harvest, its dry down in the field is dictated by environmental temperature, relative humidity (RH), wind and precipitation (rainfall). Farmers typically try to take advantage of allowing the crop to dry naturally on the field before they harvest. However, the length of time farmers wait patiently for crops to dry need to be balanced with field losses that could be incurred due to insect pests, vermin and mold and the need to prepare the land for the next crop.

Purdue, Feed the Future thinking beyond crop harvesting in Africa
May 22, 2014
WEST LAFAYETTE, Ind. - Purdue University researchers will lead a $5 million, five-year effort to help countries in sub-Saharan Africa reduce hunger and poverty fueled by food waste. By improving processing and marketing of key crops, those in developing countries can make better use of food that already is being produced but is simply lost through poor storage or processing technologies and management practices.
