Global Peeled Walnuts Industry Trends & Market Dynamics
The worldwide peeled walnuts market is valued at over $1.7 billion USD (2023) and is projected to grow at a CAGR of 5.4% until 2028 (360iResearch).
China remains the largest producer and exporter, supplying over 60% of skinned walnut kernels globally, followed by the USA and Eastern Europe. The demand escalation is driven by:
- Processed food sector and bakeries requiring skinless walnuts for better taste & texture.
- Health-conscious consumers seeking natural, oxidative-stable nut products with minimal additives.
- New culinary recipes and growing plant-based protein applications.

What are Peeled Walnuts? Technology and Process
Peeled walnuts (or skinless walnuts) are walnut kernels with the thin, bitter, brown seed coat (pellicle) removed. The result is a smooth, light-colored kernel offering a milder flavor, enhanced mouthfeel, and improved nutrient bioavailability. The primary method for producing peeled walnuts is a sophisticated wet peeling and drying process, which requires strict parameter control to ensure quality and preserve the delicate unsaturated fats inside.

Key Steps: Strict moisture control during vacuum drying maximizes shelf life, while optical inspection ensures peeled walnuts are free from shell or pellicle residues.
Material, Plants, and Industry Standardization
- Raw walnut type: Juglans regia (thin-shelled, high-omega-3 content)
- Processing: Fully food-grade stainless steel lines (304/316SS), automated hydrothermal blanchers, optical sorters (CNC-calibrated cameras for defect detection).
- Standards: ISO 22000:2018 (Food Safety Management), FDA, HACCP, meets EU pesticide maximum residue limits.
- Testing: Performed per ANSI/ASQC Z1.4-2003 Statistical Sampling Procedures. Batches validated by third-party SGS labs (SGS).
- Shelf life: 18+ months (vacuum or N₂ flush packed, ≤5% moisture).
- Color grading: L>56 in CIELAB, corresponding to “Extra LightAmber” and “Light” grades.
