🌰✨ From harvest to crunch — with flair: Learn pro techniques for selecting premium walnuts and extending shelf life. AGOLYN’s walnut and walnut kernel lots ensure consistency, plus customization solutions that pop.
📦 1. Why freshness drives your bottom line
💰 Rancid walnuts = rejected shipments + brand damage. Insist on low moisture (<4.5%) and stable oils. AGOLYN’s walnut lots are tested for peroxide value — ask for our certificate.
🧪 Always demand oxidative stability analysis before committing bulk orders.
🔎 2. Sensory & physical selection criteria
- 🎨 Color: uniform light tan kernels, no darkening.
- 👃 Aroma: fresh & sweet — no paint-like rancid notes.
- 👆 Texture: crisp snap; rubbery = high moisture.
- 📐 Size grading: consistent halves vs pieces. AGOLYN offers precise walnut kernel sizing.
🌡️ 3. Storage climate: non‑negotiable basics
❄️ Keep walnuts at 0–4°C (RH <60%). AGOLYN’s custom packaging uses high‑barrier films to slash oxygen transmission — essential for export.
📊 Data loggers avoid condensation disasters.
🧪 4. Packaging: nitrogen flushing & vacuum
Bulk 10kg cartons or retail pouches: MAP extends freshness. AGOLYN offers walnuts and Macadamia nuts with nitrogen flushing. Co‑packing with custom O2 absorbers? We do that.
- 🌙 Chilled bulk: 12‑18 months in foil bags.
- ☀️ Ambient: use opaque barrier against light.
📅 5. First‑in, first‑out with precision
🔄 Track harvest week religiously. AGOLYN labels pallets with “best for manufacturing” windows. Need re‑packing with updated dates? We handle that too.
⚙️ 6. AGOLYN’s integrated freshness protocol
From orchard shade‑drying (<4% moisture) to laser sorting and cold storage — every step controlled. Our OEM/ODM customization lets you specify grind size, roasting, or antioxidant blends. Consistent walnut supply all year.
