UN - World Food Programme Stability Study of Ready-to-Use Supplementary Food in the field Hanane Bouzambou– Food Technologist Food Safety & Quality Unit – World Food Programme IFADC - Kansas City – May 2012
Lipid Nutrient Paste Peanut Paste/Chick Pea paste (…) Specific beneficiaries target (Treatment of Moderate Acute Malnutrition) Ready to eat product Ready To Use Supplementary Food (RUSF)
WFP Requirements Validation process Product approval WFP Nutritionists Manufacturer approval WFP/UNICEF/MSF Codex / ISO principles Fortification process Stability study
Product shelflife Shelflife reduced under high temperature conditions RUSF Stability study Why? Knowledge of the product stability at different temperatures
Highly sensitive product RUSF Stability study Why? Packaging leakage Rancidity of the product Vitamins losses Oil separation
Study performed at: 30 degrees C. on a long term basis 40 degrees C. long term study to meet the WFP’s humanitarian context of work Stability study requirements To perform the product stability at different temperatures
What is the product quality when stored above degrees C.? A field stability study Why? Recurrent questions NO DATA AVAILABLE
Investigation with RUSF supplier Product stored in continuous at 50 degrees C. + Field study in Chad A field stability study Why? Recurrent questions
Field Study performed in the field - Chad Field stability study Integrated Thermo tracers Long term study- 2 years min. To evaluate the effects of transport and storage temperatures /variation on the quality of the product
Field Study performed in the field -Chad Limitation of the results interpretation Stability study Not representative to the Sahel’s climate conditions Not representative to the WFP’s multitude transport and storage scenarios EXTENSION TO THE STUDY IN SAHEL
Field Study extended to Sahel Goal ? Stability study WHAT ARE THE ACTIONS TO BE UNDERTAKEN? Containers stuck at the port more than 3 months under 40 degrees C. Preposition of these products on a long term basis at high temperature Long land-transport under tarpaulin ….
