Summary

The aim of this research was to test various techniques of packaging for dates stuffed with almond paste and Deglet Nour natural dates, products of national economic interest in Tunisia. The effects of storage temperatures and packaging types were studied from the points of view of yeast and mould evolution and water content of stored products. Natural or stuffed date storage was evaluated using four packaging types: placing the products in an amorphous polyethylene terephthalate small wrapping (APET) with simple sealing; vacuum packaging or modified atmosphere packaging with injection of two different amounts of a gas mixture (20% CO2 and 80% N2). The sample storage was carried out at three temperatures (20, 30 and 40 °C) to cause and accelerate the ageing of the dates and, thus, evaluate their shelf life.
