Stability studyStability study
Product shelflife
Shelflife reduced under high temperature conditions
RUSF Stability studyWhy?
Knowledge of the product stability at different temperatures
Highly sensitive product
RUSF Stability studyWhy?
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 40-45 degrees C.?
A field stability studyWhy?
Recurrent questions
NO DATA AVAILABLE
Investigation with RUSF supplier
Product stored in continuous at 50 degrees C.
+ Field study in Chad
A field stability studyWhy?
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 -ChadLimitation 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 SahelGoal ?
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
