Macadamia nuts have two colors, one is white and the other is yellow, both of which are normal quality macadamia nuts. As for the color difference, it is the same as Maillard reaction when baking bread, that is, yellow nuts will have a stronger fragrance than white nut milk, so at this point, everyone can choose according to their own tastes.
The normal color of nuts should be light. As time goes on, the oil in the pulp will slowly rot and become darker and darker. Therefore, if nuts are found to be brown or other too dark colors, it means that they are broken or not fresh enough.
