Shelf Life
Period a food remains safe and meets quality specifications
Shelf Life is the period during which a food product remains safe, retains its desired sensory, chemical, physical, and microbiological characteristics, and complies with any nutrient or label declarations, when stored under recommended conditions.
For Egyptian fresh produce exports, shelf life is a critical commercial parameter. The shelf life of a Egyptian mango destined for EU markets includes: - **2-3 days** at packhouse (post-harvest, pre-cooling, packing). - **6-10 days** in transit (refrigerated container, ocean freight to EU port). - **2-4 days** at EU distribution center. - **2-5 days** at retail. - **2-4 days** consumer storage.
Total shelf life from harvest to consumer plate: typically 14-26 days. Each day of cold-chain disruption can shorten this by 2-4 days.
Shelf life determination methodologies: - **Direct measurement**: product stored under typical conditions, evaluated periodically until end-of-shelf-life criteria are met. - **Accelerated shelf life testing (ASLT)**: storage at elevated temperatures, mathematical extrapolation to typical conditions. - **Predictive microbiology**: software models (Pathogen Modeling Program, ComBase).
For Egyptian exporters, common shelf life issues: - **Anthracnose** development on mangoes (fungal, post-harvest). - **Internal browning** in citrus from cold injury. - **Senescence** in leafy greens (yellowing, wilting). - **Botrytis** on strawberries (gray mold).
