Abstract
Over the past few years, the importance of food powder shelf life has gradually increased for food product producers. Consequently, the objective of this study was to investigate how storage conditions impact the quality characteristics of roasted date seed powders and to determine the predictability of their shelf life. The powders were packaged in ALP pouches and stored under various conditions. The powders' properties were assessed at seven-day intervals over a 12-week storage period. The findings indicated that both storage time and method significantly influenced the powder properties. Additionally, the powders were found to be microbiologically stable, exhibited poor flowability, and were non-hygroscopic across different storage conditions. The statistical analysis indicated that both zero-order and first-order reaction models were successful in predicting changes in moisture content and total color difference. As a result, the rate of moisture content change serves as a reliable indicator for estimating the shelf life of powders made from roasted date seeds.
