Expert: Cassava cannot be eaten raw
Be sure to choose "edible" varieties
Post Scientist of the National Cassava Industry Technology System
Shen Zhangyou said
Cassava is divided into:
There are three types: edible, feed and industrial
Among them, the edible cassava varieties are "Huanan No. 9" (Huangxin Cassava), "Guire No. 10" (white cassava) and "Gui Cassava No. 11" (white cassava) that have been popularized nationwide. Be sure to buy edibles when you eat!
Q: Is cassava really poisonous?
Shen explained that fresh cassava contains a class of endotoxins called cyanogenic glycosides, which will produce toxic hydrocyanic acid when degraded. "Fresh cassava has a high level of hydrocyanic acid in the outer skin, so eating raw cassava is at risk of poisoning. ”
However, hydrocyanic acid is not only found in cassava, but also sorghum, corn, flaxseed, ginkgo seeds, and bamboo shoots that Sichuan people love to eat, and many crops are also found in seedlings or vines. Therefore, cassava is not inedible, but it cannot be eaten raw.
Shen Zhangyou also said, "The content of cyanogenic glycosides (hydrocyanic acid) in different varieties of cassava varies greatly, and according to the standards of the Codex Alimentarius Commission (CAC), cassava that has been simply processed such as peeling and soaking, and the hydrocyanic acid content is less than 50mg/kg, is classified as edible cassava." "According to each person's physical condition, the critical point of hydrocyanic acid that each person can tolerate will be different," generally speaking, the human body ingests less than 50 mg of hydrocyanic acid is within the safe range. ”
"Although cassava is not as well-known as sweet potatoes and yams, it is the world's fifth-largest food crop and the world's third-largest source of starch. Shen Zhangyou said that more than 1 billion people in the world depend on cassava for survival, which is equivalent to the ration of 1/7 of the earth's people.
Q: Why do some netizens have a series of adverse reactions after eating tapioca syrup?
Shen believes that it is not necessarily caused by eating cassava, "There are many causes of poisoning, including hygiene, cooking methods, inadvertent raw food, or the presence of other sources of infection during transportation." Cassava poisoning, which is usually acute and sudden. If you have mild symptoms such as dizziness and nausea, you can drink plenty of water to relieve it, but if the condition is more serious, you must seek medical attention in time. ”
