Effect of Harvest Period on the Proximate Composition and Functional and Sensory Properties of Gari Produced from Local and Improved Cassava (Manihot esculenta) Varieties

Table 3

Effect of the harvest period (12 and 15 months after planting) on the bulk density, the water absorption capacity (WAC), the swelling power, the least gelation concentration and the free cyanide content of cassava gari. Gari are produced from local (EN and AD) and improved (TMS92/0326, TMS96/1414 and IRAD4115) cassava varieties harvested in dry season at 12 months and in rainy season at 15 months after planting (12MAP and 15MAP). These garis were compared to the commercial cassava gari (CG). Values are given on the dry weight basis.
