How to distinguish the authenticity of poisonous yam

Yam is one of the foods that people are familiar with. In daily life, people often eat various foods made from yam, and they taste very good. Yams are divided into good yams and poisonous yams. Poisonous yams are very harmful to the human body. We should be careful to avoid eating it, but people may not be able to distinguish the good from the bad yams in life, so how can we tell the real poisonous yams from the fake ones?

To distinguish real and fake yam, look at the "heart line"

There is no core line in the middle of yam slices, but there is a core line in the middle of cassava slices. Although the core line is very small, you can see it if you observe carefully. Some cassava chips are peeled too thin, so the core will often fall out after drying. However, when the core falls out, a small hole will be left behind. If there is a small hole in the middle, it must be cassava chips. Look at the edges. The skin of yam is very thin and will be peeled clean before slicing. The skin of cassava is much thicker than that of yam. Some thumb-sized cassavas are difficult to peel because they are too small, and counterfeiters often do not take the time to peel them. Therefore, after cutting them into thousands of slices, if you find that the edge of the yam has a very thick skin, then this kind of yam is generally counterfeit and inferior. Not only does it taste bad, but the nutritional content is also greatly discounted. Therefore, it is best not to eat this kind of yam.

Because yam and cassava are similar in appearance, many friends often buy cassava when buying yam. In fact, if we want to know whether we bought yam or cassava, there is a very simple method, which is to observe after cooking. Yam is generally easy to cook, while cassava is difficult to cook. After cooking, yam has a mushy, powdery texture, while cassava has a harder texture. The skin of good yam is intact, mucus-like, with snow-white fractures, high in mucus and low in moisture. The skin can be fried fresh, or dried and boiled into soup or porridge. Peel the skin before eating to avoid abnormal taste such as numbness or pricking.

Above we have introduced in detail some good methods to identify yam. In fact, the methods to identify yam in daily life are also very particular, so we all need to remember the above good methods to identify yam. When we buy yam in life in the future, we can use the above methods to identify the authenticity and quality of the yam.
