Effects of processing methods of cassava (Manihot esculanta) leaves on detoxification of cyanogenic compounds: A short review

Leaves of Manihot esculanta are rich in proteins as well as consist with carbohydrate, beta carotene, vitamin C, B1, B2, and other micro and macro nutrient elements which could be used to fulfill the nutrient requirement of humans to a certain extent. Nutrient profile of cassava leaf is determined by the cultivar, part of the plant, maturity period and harvesting period of leaves, soil fertility level, and the drying temperature. The nutrient availability is limited by the presence of high amount of anti-nutrients; fiber, cyanide, tannin and phytin. Moreover, presence of cyanogenic compounds results cynogenic toxicity which leads to chronic and acute health disorders. As reported, the cyanogenic toxicity of cassava leaves can be reduced by using several processing methods. This paper reviews the current literature evidences on the use of cassava leaves as a nutrient source of the human being and the efficient detoxification methods among the traditional processing methods.
