How to distinguish the authenticity of Dayao walnuts

Selection method for high-quality cardboard walnuts:

One pick: Unlike other products, walnuts are not necessarily the bigger the better. Long hanging time can cause the shell to become thicker, affecting the kernel yield. At the same time, some fruit shells may not meet the standards of cardboard walnuts

Two picked plump: The plump fruit is naturally ripe, with a delicate taste and a better aroma

Three picking uniformity: The color of the fruit is natural, and the size is round and uniform

Four picking shell: The shell is thin and white, and the kernels are easy to peel out. However, there are illegal merchants selling bleached walnuts on the market, so it is not necessarily better for the shell to be whiter. Walnuts that are truly naturally dried will have a slight yellow color and a textured reflection
