2. Harvesting
Unlike other nuts, macadamias fall naturally from the tree when ripe. Farmers use specialized machinery to collect the nuts from the ground, ensuring minimal damage.
3. Processing
Once harvested, the nuts go through several steps:
Dehusking – Removing the outer green husk.
Drying – Reducing moisture content to prevent spoilage.
Cracking – Breaking the hard shell to extract the kernel.
Roasting – Enhancing flavor through controlled heating.
4. Packaging and Distribution
After quality checks, the nuts are packaged and shipped worldwide. Many Big Island farms sell directly to consumers through on-site stores or online.
