The color of buckwheat noodles does not represent quality and taste. Black buckwheat noodles contain buckwheat hulls, which makes the flour darker and more bitter to eat. White buckwheat noodles are made of pure buckwheat, without buckwheat hull components, with a color close to white and a fragrant taste. The color and quality of buckwheat noodles are not necessarily related. When choosing buckwheat noodles, we should pay attention to the composition and taste of flour, not the color.
