Some natural foods are poisonous but loved by humans. Therefore, processing them is a concern for housewives.
Tapioca
Tapioca is a popular food that many people love to boil, cook sweet soup, make sticky rice… Tapioca is also a supportive food for diabetes group because they have a high amount of resistant starch, preventing sudden blood sugar levels.
However, in natural tapioca, there is a toxic substance called hydrocyanic acid (HCN), a substance that can cause human death with a very small and very fast amount. The amount of this toxin depends on the place of cultivation and the type of tapioca. Bitter variety and high-yield tapioca contain more HCN than sweet tapioca. The toxin is mostly in two ends of the tapioca tubers, tapioca fiber and most in the tapioca peel.
Therefore, to eliminate the toxin in tapioca:
– Before processing, peel the tapioca and soak it in water for several hours and change the water to remove the toxin through the water. Remove the tapioca fiber before making sticky rice.
– Soaking tapioca in rice water also helps remove toxins quickly
– Absolutely do not eat raw tapioca, it must be fully cooked
– When boiling tapioca, open the pot lid to let the toxin evaporate
– Sun-dried tapioca also helps reduce this toxin, so if you want to store tapioca for a long time, you have to dry it and when processed into powder, soak and filter it several times with water and sun dry it to eliminate the majority of the toxin.
– Eating tapioca with sugar or honey helps neutralize the toxin better.

However, fresh mushrooms contain a toxic substance called morpholine, which is sensitive to light, so eating it can cause itching, nausea, diarrhea, even severe irritation and skin necrosis.
