The Effect of Physical Treatments on Reduction of Microbial Load and Control of Storage Pests in Ghasb and Shamsaei Date Varieties

Document Type : Research Paper

Abstract

In this study, heat treatments (Temperatures of 50 oC, 60 oC and 70 oC for 1h & 2 h in 75-80% RH) and low temperatures (0 oC and -5 oC for 24 h and 48 h) were used in controlling of storage pests in Ghasb and Shamsaei date varieties. After treating and packaging, the date varieties were stored in cold room and also at ambient temperature for 6 months and the rate of pest infestation, microbial and chemical analysis were carried out after 2 interval months of storage. Oligonychus afrasiaticus and Ephestia figulliella were reported as important pests of Ghasb and Shamsaei dates in Shahdad region. Temperature of 70 oC for 2 h was the most effective for disinfestation and reduction of microbial load in Ghasb and Shamsaei date fruits. The rate of pest infestation and acidity (as lactic acid) in the samples of stored at ambient temperature increased during storage. The samples stored in cold room had not only the lowest rate of acidity and pest infestation but also the rate of infestation and acidity significantly reduced in these samples during storage. Cold room was effective in preventing the activity of microorganisms and pests in Ghasb and Shamsaei date varieties.
