3. Manufacturing Process: Macadamia Nuts Production Flow

Macadamia Nuts manufacturing process

The industrial production of Macadamia Nuts is a multi-stage operation that requires rigorous control and high-grade machinery for optimal output. The process, certified under international standards such as ISO 22000 and conforms to FDA requirements, is summarized as follows:

Macadamia Nuts processing flow chart
  1. Harvesting & Pre-cleaning ⇨ Collection from matured trees, removal of field debris using vibrating sieves.
  2. Dehusking ⇨ Mechanical removal of outer husk; minimizes kernel damage (source).
  3. Drying ⇨ Hot-air or solar dryers reduce nut moisture to
  4. Shelling ⇨ CNC-calibrated shelling machines, precision-cut for high kernel yield.
  5. Sorting & Grading ⇨ Optical scanners class by size, color, defect for commercial grades (Style 1/2/3 etc).
  6. Packing/Testing ⇨ Vacuum/sealed packaging; batch testing per ISO 22000 for microbe, FFA, and impurities.
  7. Logistics ⇨ Temperature and humidity-controlled shipping worldwide.
"Advances in mechanized shelling and automated optical grading have reduced kernel breakage by 12% while enhancing compliance with international food safety standards." – Journal of Food Engineering

4. Material, Testing Standards & Typical Application Sectors

  • Material: Dense, oil-rich macadamia kernel with proprietary genetic strains selected for high monounsaturated fat and low contaminant uptake.
  • Manufacturing: Multi-stage process including initial removal of fibrous husk, then high-precision mechanical shelling (akin to CNC for hardware), and multi-phase optical/electronic grading.
  • Testing Standards: All batches tested under ISO 22000 (Food Safety), FDA compliance, and HACCP protocols, with chemical and microbiological analyses.
  • Service Life: Up to 24 months (vacuum-packed, ambient conditions, NCBI studies.
  • Key Industries: Food & Beverage, Premium Snacks, Confectionery, Cosmetics, Industrial Bakery, Oil Extraction, and Nutrition Supplement sectors.
  • Application Advantages:
    • High natural antioxidant content (tocotrienols, vitamin E) for product preservation
    • Superior oxidative stability, suitable for extended shelf products
    • Corrosion resistance to food acid/bases in industrial use; minimal spoilage
    • Energy saving in roasting and processing due to low initial moisture
