3. Implementation suggestions and application cases

Testing method suggestions: In actual testing, the determination of kernel fat content should refer to GB 5009.6 standard to ensure data accuracy. At the same time, the measurement of opening width and opening arc should be strictly carried out in accordance with the requirements of Appendix A.

3.1 Practical application of shell nut classification

Take a nut processing company as an example. When purchasing shelled macadamia nuts, they should be graded according to the technical requirements of Table 1. The first-level extra-large fruit (D≥26 mm) is suitable for the high-end market, while the second-level large fruit (23≤D<26 mm) can be used for mid-range products.

3.2 Key points of kernel quality control

During the processing, the control of the whole kernel rate is very important. According to Table 3, the requirement for premium whole kernels is ≥95%. Enterprises can improve the whole kernel rate and reduce the broken kernel ratio by improving shelling technology.
