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
Ready To Use Supplementary Food (RUSF) • Lipid Nutrient Paste • Peanut Paste/Chick Pea paste (…) • Specific beneficiaries target (Treatment of Moderate Acute Malnutrition) • Ready to eat product
WFP Requirements Validation process • Product approval • WFP Nutritionists • Manufacturer approval • WFP/UNICEF/MSF Codex / ISO 22000 principles Fortification process Stability study
RUSF Stability study Why? • Product shelflife • Shelflife reduced under high temperature conditions • Knowledge of the product stability at different temperatures
RUSF Stability study Why? • Highly sensitive product • Oil separation • Packaging leakage • Rancidity of the product • Vitamins losses
Stability study requirements To perform the product stability at different temperatures • 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
A field stability study Why? Recurrent questions • What is the product quality when stored above 40-45 degrees C.? NO DATA AVAILABLE
A field stability study Why? Recurrent questions • Investigation with RUSF supplier • Product stored in continuous at 50 degrees C. • + Field study in Chad
Field stability study • Field Study performed in the field - Chad Integrated Thermo tracers • To evaluate the effects of transport and storage temperatures /variation on the quality of the product Long term study- 2 years min.
Stability study • Field Study performed in the field -Chad • Limitation of the results interpretation 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
Stability study • Field Study extended to Sahel • Goal ? 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 ….
