You can determine how much moisture your hazelnuts have lost by regularly measuring their weight. You need accurate digital scales. This method won’t tell you the absolute moisture level, just whether they are stabilised.
This is essentially the same process as described in Simple Moisture Content Calculation, but this method happens naturally over a longer time.
Weigh the sample when nuts are first harvested. Re-weigh regularly until the weight is the same for 3 measurements.
