Shelf Life — Management and Testing for Paprika¶
Definition¶
Shelf life is the period during which a paprika product, when stored under specified conditions, retains its quality attributes within defined acceptable limits. The primary quality attribute that defines end-of-shelf-life for paprika is ASTA color value — typically set at 80% retention (e.g., from ASTA 160 to ASTA 128).
Shelf Life by Product Form¶
| Product Form | Typical Shelf Life (20°C, barrier) | Limiting Factor |
|---|---|---|
| Whole dried pods | 24 months | Moisture reabsorption, pest risk |
| Crushed/flakes | 18 months | Surface oxidation |
| Standard powder (40 mesh) | 12–18 months | Carotenoid oxidation |
| Fine powder (60+ mesh) | 8–12 months | Rapid surface area oxidation |
| Oleoresin (sealed, 4°C) | 24 months | Carotenoid isomerization |
Accelerated Shelf Life Testing (ASLT)¶
ASLT at 40°C/75% RH for 3 months corresponds to approximately 12 months at 25°C/50% RH using a Q₁₀ = 2.0 factor (Arrhenius model).
