Ready-to-Use Therapeutic Foods (RUTFs) have to recover health status of malnourished children without clinical complications.

Abstract
Ready-to-Use Therapeutic Foods (RUTFs) have to recover health status of malnourished children without clinical complications. If produced in loco, RUTFs should be stable when stored at room temperature and unprotected atmosphere. The aim of this work was to verify the oxidative stability of 4 RUTFs, by means of conjugated dienes and malondialdehyde (MDA) content at 3 temperatures for 4 weeks. RUTFs initially presented a different content of peroxydiene and their increase was well described by pseudo zero order models. Kinetic constants at 60°C were higher than those estimated at 30° and 40°C. MDA values were very low (≈0.48 µg/ml after 4 weeks). Those products were quite stable over 2 weeks even if stored at 40°C in an unprotected atmosphere.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
