Abstract: (4574 Views)
One of the most important problems in date processing is unsuitable storage conditions, packaging types and then changing physicochemical characteristics.In this research date fruits (Kabkab variety) were packed within aerobic atmosphere and vacuumed PA/PE pouches and stored at different temperatures (-20, 4, 25 and 40 ºC). The samples were evaluated for textural parameters (hardness, adhesiveness, cohesiveness and springiness) monthly during the storage period up to 6 months. The storage temperature, time and packaging type greatly (P < 0.01) affected hardness, cohesiveness and springiness tested in date fruits during storage.Time and packaging type had significant effects on date adhesiveness, while temperature did not affect it. All texture properties were higher in the dates stored at 40 ºC within all packaging types in sixth month. An increase of hardness was detected for atmospheric and vacuum- packed datesthroughout the storage period. However, it was noted that increasing was significantly greater at 40 ºC compared to other storage temperatures.
