This program is concerned with post-harvest handling of fruits and vegetables including packaging, storage and processing. The program was charged with the responsibility of:

  • Developing appropriate post-harvest handling of fruits and vegetables to ensure reduction in post-harvest losses and process crops into value added product.
  • To upgrade traditional processing practices of horticultural produce to make them more effective and adaptable.


Processing Division
Concerned with post harvest utilization and processing of horticultural crops into value added products

Horticultural Nutrition Division
Concerned with the nutritional assessment of developed products

Quality Control Division
Concerned with the qualitative evaluations of developed horticultural products

Major Activities of the Programme

  • Evaluation of chemical and  nutritional  components of raw and processed fruits, vegetables and spice  products
  • Development of value added products from horticultural crops.
  • Development of technologies for post harvest management of horticultural crops.
  • Provision of information on horticultural crops handling and storage at home and industrial level.
  • Evaluation of microbiological status and safety of horticultural produce and processed products.
  •  Working in partnership with stakeholders in fruit juice processing, especially standardization and establishment of fruit juice processing lines.
  • Training

Major Research Achievement in Product Development Programme

In the area of processing and product development values have been added to: 

  • Plantain, Banana, Mango, Citrus, Pineapple, Roselle, Grain amaranth and Watermelon.
    Orange juice concentrate had been developed in an attempt to solve the shortage of raw materials supplies to industries engage in fruit juice processing. The prototype samples were acceptable to industries as substitute ingredient in squash, nectar and drink manufacture.
  • Citrus pectin are used as thickening/gelling agents in a large variety of food, pharmaceuticals and cosmetic products which include jams jellies, marmalades etc.
  • Crude pectin has also been extracted from the peels of citrus fruits particularly lemon peel.
  • Crude papain has been produced from three varieties of pawpaw. Papain is an ingredient in several pharmaceutical preparations.
  • Citric acid has been produced from rough lemons and sour orange. Citric acid is a necessary constituent in juices and soft drink production.
  • Production of baby weaning and enrichment foods from plantain and soyabean (Soyamusa)
  • Pap (Yoruba-Ogi ), has been prepared from grain amaranth. The latter has been added to enrich carbohydrate based diet like gari and elubo by incorporating the flour.
  • Confectioneries products have been prepared from composite flour consisting of wheat and plantain flour mixture.
  • Plantain based biscuit and cake: One hundred percent plantain flour has been successfully utilized in producing cakes, short bread, biscuit and cookies.
  • Jams, jellies, marmalades, chutney, relish and preserves have been made from citrus, pineapple, pawpaw, guava, passion fruit, mango and indigenous fruits.
  • Dehydrated products / Fruit leathers: Good quality fruit leathers have been produced from dehydrating citrus, pineapple and mango. Leathers are generally eaten as snacks and could be preserved for 9–12 months.
