I. Look at the "heart vein"
Yam slices do not have a heart vein in the middle, whileCassavaThe slice has a heart vein in the middle, even if the heart vein is small, as long as you observe carefully, you can see it.Some cassava slices, because they are peeled thinly and dried, the heart vein often falls out. However, if the heart vein falls out, a small hole will remain.If there is a small hole in the middle, it must be a cassava slice.Look at the edge.Yam skin is very thin and is usually peeled before slicing.Cassava skin is much thicker than yam skin.Some small cassava, as small as a thumb, are difficult to peel, so counterfeiters will not spend time peeling them. Therefore, after slicing into many pieces, thick skins will remain on the edges.Any slice with thick skin must be fake yam.
II. Feel the difference

How to store fresh yams: Fresh yams are easily oxidized by oxygen in the air, and contact with iron or metal will cause browning. Therefore, when cutting yams, it is best to use a bamboo knife or plastic knife. First draw a line on the skin, then peel it into segments.The cut edge is prone to oxidation. You can soak it in rice wine first, then dry it with a hair dryer to promote healing, and then wrap it in a paper towel, wrap it with several layers of newspaper, and put it in a cool corner.Yam slices should be immediately immersed in salt water to prevent oxidation and darkening.
