How to select high-quality thin-skinned walnuts:
First, choose the size: Unlike other products, the bigger the walnut, the better. Long fruit hanging time will cause the shell to become thicker, affecting the kernel yield. At the same time, some fruits will have too thick shells and cannot meet the paper-skinned walnut standard.
Second, choose fullness: Full fruits are naturally ripe, with a delicate taste and better fragrance.
Third, choose uniformity: The color of the fruit is natural, and the size is round and uniform.
Fourth, choose the shell: The shell is thin and white, and the kernel is easy to shell, but there are illegal merchants selling bleached walnuts on the market, so the whiter the shell is, the better. The walnuts that are truly naturally dried will be slightly yellow and have a textured reflective texture.
