Cassava is a poisonous plant, and its toxicity is the whole plant. Fresh tubers are more toxic. Symptoms of poisoning are mild, such as nausea, vomiting, diarrhea and dizziness. In severe cases, people have difficulty breathing, rapid heartbeat, dilated pupils and even coma. Finally, they went into convulsion and died of respiratory failure. Therefore, you should not eat too much cassava, and pay attention to the correct way to eat it. The cassava processed in this way can be safely eaten. Because toxic substances have been removed during processing.
Benefits of cassava starch:
1, the potassium content in cassava is very rich. Eating more cassava in patients with hypertension can effectively inhibit the increase of blood pressure. The dietary fiber in cassava can stimulate gastrointestinal peristalsis, accelerate the excretion of feces and toxins in the body, and play the role of clearing intestines and detoxifying. Zinc in cassava can promote brain intelligence development and prevent Alzheimer's disease.
2. Cassava is low in fat and high in starch, calcium, potassium, zinc and other elements. Eating regularly will not only lead to malnutrition, but also delay the premature appearance of obesity. The proportion of lysine and tryptophan in cassava is large, which is helpful to promote the synthesis of human fatty acids and avoid the physical retardation of children. Non-protein nitrogen in cassava can soften the blood vessel wall, increase the toughness of the blood vessel wall and prevent the blood vessel from hardening and rupture.

Other uses of cassava starch:
1, making candy:
Cassava starch and various modified starches have many uses in candy production, such as gelatinization, thickening, crystallization control, bonding, film formation and luster enhancement. Low viscosity tapioca starch is widely used to gel candy, such as frozen and chewing gum. Acid-hydrolyzed starch is the most commonly used, because it has excellent reversibility and gelling ability, and these characteristics are more obvious when sugar is involved. Dry starch is used as a release agent in candy manufacturing. Starch-based polysaccharide realized the production of sugar-free chewing gum.
2, making drugs and cosmetics:
Cassava starch and modified starch can be used as binders, fillers and disintegrants in tablet production. Specially modified starch can be used as a carrier for emollients, which are usually mineral oil-based substances. Other modified starches can be used as emulsifiers, encapsulating agents (vitamins), styling agents (hair gels) and thickening agents (shampoos).
3. Making biodegradable materials:
Cassava starch and modified starch can be mixed with petroleum-based or synthetic polymer materials to improve the biodegradability of the materials, thus minimizing the production cost of this environmentally friendly material.
