In addition, the disease incubation period after ricin poisoning is usually long, which is not easy to distinguish. Obviously, castor beans are very dangerous. However, it has been proved that castor bean is toxic and can be destroyed at high temperature. There are the following examples: 1, castor oil cake is very toxic, but it can basically detoxify when it is steamed at a high temperature above 100 degrees for more than half an hour. The protein content of oil cake detoxified at high temperature is as high as 30%, which can be used as feed. Figure 2. According to the elderly, castor seeds are used to supplement edible oil because of their high oil content during the period of material shortage.
Although it is dangerous, the situation is critical. They usually eat three or four tablets at a time. The key is to heat castor beans at high temperature, which may destroy the toxic ricin in castor beans. Figure 3. The roots and leaves of castor have high medicinal value and can be used to treat various diseases after treatment. Of course, these examples are not to prove that castor beans are edible, but their toxicity is usually suppressed, far from being biological weapons. The value of castor bean lies in that it can be used to extract industrial oil. The oil content of castor oil exceeds 50%, and castor oil has high viscosity and low freezing point. As an important raw material, cold-resistant and high-temperature-resistant materials are widely used in various industrial occasions.
The output of modern castor oil has increased rapidly, precisely because it can be used to make advanced lubricating oil urgently needed in industry. In short, as a plant, castor bean, like many other plants, the existence of toxicity is a normal phenomenon. Will not become a biological weapon. But the danger is real, even if the toxicity can be destroyed at high temperature, the risk is too great for untrained eyes. It is recommended not to plant this plant in densely populated areas.
