2. Macadamia Nuts: Core Material Properties & Technical Advantages
  • Material: 100% natural Macadamia integrifolia or Macadamia tetraphylla, known for high monounsaturated fat (MUFA) and low palmitic acid.
  • Chemical Profile: Protein (8–9g/100g), Fiber (6–7g), Vitamin B1, and unique phytosterols.
  • Standard Compliance: ISO 22000, FDA, BRC, and Kosher certifications for food safety and traceability.
  • Processing Grades: Whole, Style 1, Style 2, Style 4 (broken), and roasted/dry-roasted.
  • Durability: Shelf-life up to 24 months (under nitrogen pack; ≤10ºC storage).
  • Corrosion & Spoilage Resistance: Ultra-low moisture, nitrogen-packed, anti-fungal treatments assure freshness & stability.
  • Versatility: Used across confectionery, snacks, ice cream, bakery, cosmetics (oil), and plant-based milk sectors.

Compared to other nuts, Macadamia Nuts offer a richer, creamier taste, higher oxidative stability (due to high oleic acid), and lower risk of aflatoxin contamination—a critical factor for food manufacturers prioritizing safety and international export standards.

3. Macadamia Nuts Manufacturing Process: Step-by-Step Visual Guide
1. Harvest & Collection
Hand-picked from mature trees. Clean, undamaged, mature nuts only. 2. De-husking
Outer husk rapidly removed within 24h to prevent mold. 3. Drying (Curing)
Hot-air drying (Air: 30–40ºC, ~5–10% humidity) to reach <1.5% moisture
4. Cracking
Mechanical shelling by CNC precision crackers to avoid kernel breakage (<2% breakage) 5. Sorting & Grading
AI visual sorters grade kernels by size, color, and integrity. 6. Packaging
Nitrogen-flush, vacuum-sealed in multilayer food-safe films. Metal-detection with HACCP traceability labelling.
Quality inspections (ISO 22000/FSSC 22000) at each step ensure safety, traceability, and compliance with FDA and EU standards.

8. Professional FAQ: Macadamia Nuts Industry Terms Explained
Q1: What is the standard kernel size grading for Macadamia Nuts?
A: Kernel size is typically classified as Style 0 (Extra Large ≥22mm), Style 1 (Whole ≥20mm), Style 2 (Half kernel), Style 4 (Broken pieces), in compliance with INC/ANSI Standards. This grading affects both price and culinary suitability.
Q2: How is the moisture content controlled and why does it matter?
A: Moisture is reduced to ≤1.5% via controlled hot-air curing. Low moisture improves shelf-life, inhibits mold, and ensures crunchy texture—meeting ISO 665 and FDA microbiological safety guidelines.
Q3: What primary material(s) are used in premium Macadamia Nuts?
A: Only mature Macadamia integrifolia or Macadamia tetraphylla kernels are used, with high oleic acid and monounsaturated fatty acids (MUFA). Admixture from other cultivars is strictly avoided by certified vendors.
Q4: What are the testing standards for Macadamia nuts safety?
A: Comprehensive testing covers ISO 22000, FDA, CODEX STAN 210 for heavy metals, pesticides, aflatoxin, and microbial load. Each batch is tracked using digital records and random sample audits.
Q5: How are Macadamia Nuts packed to ensure product integrity?
A: Bulk and retail packs use multi-layer, food-grade films with nitrogen-flush and vacuum sealing to prevent oxidative rancidity, contamination, and infestation. All packaging is FDA and EU compliant.
Q6: What are “Free Fatty Acids” (FFA) and why should their levels be low?
A: FFA are breakdown products of nuts’ fats and oils. In Macadamia Nuts, FFA < 0.8% is critical (per CODEX) to prevent rancidity, off-flavor, and maintain export-grade quality.
Q7: What is the shelf-life and warranty commitment for Macadamia Nuts?
A: When stored at ≤10ºC and vacuum-packed, shelf-life of 12–24 months is standard. Yuyang Melon Co. provides a minimum 12-month warranty with technical support on all Macadamia Nuts shipments.
Q8: Are custom blends or ingredient solutions available?
