Sweet potato is a coarse grain, which is common in our daily life. It is also a staple food that people often eat at the table. For this sweet and fragrant food, it is always considered as the most popular food. Whether it's steamed, boiled or baked, it's all people's favorite taste. But for the sweet potato now, the price is not very expensive. Basically, they all weigh more than 2-3 yuan. For some areas with large wholesale volume, a catty may even be less than 1 yuan, which can be said to be an affordable sweet potato.

There are many varieties of sweet potatoes. Some kinds of sweet potatoes are several times more expensive than ordinary sweet potatoes. For example, purple potato is one of them. Their outer skin and inner layer are purple, and their nutritional value is higher than that of sweet potatoes. However, there is another kind that is more expensive than purple potato. It is said that this sweet potato is poisonous, and it can be sold to 20 yuan for at least a catty in the market. At present, few people in China regard it as a staple food, but it is regarded as a treasure abroad and should be eaten every day. This is cassava. Some people may or may not have heard of cassava, but it was once a very precious food for people. In the last century, people planted a lot of cassava and used it as a daily necessity. Because there was nothing to eat then, cassava was a rare staple food. At this point, we also need to talk about starch, which is rich in content, which is also the key to people's choice.

But when you eat cassava, you should soak it in water, mainly to sterilize it. This is because cassava contains some harmful elements. This is a necessary process. From people's point of view, this cassava is not as valuable as other sweet potatoes or miscellaneous grains, and it is not convenient to eat, so people plant less. However, cassava still contains some starch elements and has certain uses. So it is basically used to extract starch, which is a major application of cassava in China.

However, although this is true at home, it is quite different abroad. Cassava is even considered as a very important staple food. For example, in Africa, the living conditions in many places are somewhat backward. In their eyes, cassava can feed itself in saturation, but it shows great practical value. Therefore, cassava is still a very important crop in some parts of Africa, and its value far exceeds that of many other plants. As far as foreign cultivation is concerned, farmers will also pay close attention to its output and market conditions, so cassava is a common food in the market here. As far as China is concerned, even if the living conditions are different from those in the past, it must be said that from the understanding of cassava as a treasure abroad, the market value of cassava is not small, and farmers can appropriately variety cassava. The so-called thing is rare. If you know the benefits of cassava, you may like this food very much. Farmers can have a try first. If cassava is planted properly, it is also a way to increase wealth!
