Iran is among the top global producers of pistachios, known for distinct varieties like Kalleh Ghouchi, Fandoghi, and Ahmad Aghaei, offering large kernels, rich taste, and ideal oil content favored in premium segments.
Scientific review shows that optimal drying and storage conditions are essential to preserve nut quality:
Ideal storage: 0–10 °C with 65–70 % relative humidity, or higher (>10 °C) with <32 % RH — helps minimize fat oxidation and microbial activity during bulk storage
Effective dehydration reduces moisture to 4–6 %, which prevents fungal growth and aflatoxin formation; moisture above that dewpoint increases risks
Recent peer-reviewed studies highlight:
PET film packaging maintains shelf life up to ~5 months, superior to LDPE and PVC at delaying moisture absorption and aflatoxin formation
Vacuum-packed nylon or multilayer films, tightly sealed and moisture/non‑oxygen impermeable, significantly slow fungal spoilage under humid conditions
Active packaging with antioxidants (e.g., essential oils or stannous chloride), under modified atmospheres, extends sensory and microbial shelf life in pistachios
Innovations include edible antioxidant coatings such as gum arabic or chitosan enriched with thyme or algal extracts:
Application on pistachios significantly reduces enzyme browning, lipid oxidation, and microbial counts—even over one month of storage
For example, 6 % gum arabic + thyme oil coating lowered PPO enzyme activity and peroxide index while preserving phenolic content and sensory attributes
Iranian exported nuts for EU and GCC markets must meet:
Aflatoxin ≤ EU legal limits, pesticide residues, moisture content
Halal certification and safe cold-chain packaging for GCC
