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 1
Impact of the harvest period (12 and 15 months after planting) on the pH, the dry matter, the ash, the crude proteins, and the free amino acids content of cassava gari. Garis are produced from local (EN and AD) and improved (TMS92/0326, TMS96/1414, and IRAD4115) cassava varieties root 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.
