1. Industry Trend Analysis: Skinless Walnuts—Market Evolution and Demand Surge
According to the International Nut and Dried Fruit Council (INC), the global walnut market surpassed 1.1 million metric tons in 2023, with demand for skinless walnuts (peeled walnut kernels) growing at a CAGR of 7.2%. Consumers in Europe, North America, and East Asia increasingly prefer skinless walnuts for their reduced astringency, brighter appearance, and versatile food processing applications. As pricing remains competitive—peeled walnuts price averaging $7,200–$8,600/MT (FOB China, 2023)—premium product differentiation now hinges on processing innovation and quality certification.

Packaging
- Harvesting & Cleaning: Walnuts are sourced from select orchards in Yunnan, China (altitude 1,800–2,800m), ensuring high kernel density and minimal pesticide residue.
- Shell Breaking: Automated cracker lines break the shell, minimizing kernel breakage rates (<7%).
- Boiling/Steaming: Kernels are gently boiled (90–98°C) to loosen pellicle without nutrient loss.
- Skin Peeling: Precision rollers and air-jets strip pellicle, achieving >98% peeled surface, essential for aesthetic and taste profile.
- Cooling & Drying: Rapid low-temp dehydration (below 50°C) stabilizes oil content and prevents oxidation.
- Sorting & Inspection: Advanced vision systems remove off-spec kernels, shell fragments, color defects (using X-ray & optical sorters).
- Packing: Modified-atmosphere packaging (MAP) extends shelf life; all packaging is FDA-approved, food-grade PET or LDPE.
Key Manufacturing Technologies Used:
- CNC Sorting Machines, ensuring uniform kernel sizing (<±5% deviation)
- Low-Temperature Vacuum Drying (<50°C, preserves Peroxide Value < 2.0 meq/kg)
- X-ray Detector and Optical Sorters, guaranteeing physical/biological safety
- Compliance with ISO 22000:2018 and FDA 21 CFR 110 for food hygiene and traceability
