Abstract

composition of bitter cassava tubers. The proximate composition of freshly harvested tubers (FHT), Tubers Stored for 4 days (TS4D) and Tubers Stored for 8 days (TS8D) were determined using standard methods while the cyanide content was determined by linamarase digestion method using an autoanalyzer. The proximate analysis for FHT showed carbohydrate (20.6 ± 1.27 %), crude protein (2.61 ± 0.01%), ash (3.0 ± 1.41 %), crude fat (7.0 ± 4.24 %), total solid (29.75+0.35%), and moisture contents for FHT were 31.45 ± 0.77% respectively. The values obtained for TS4D are ash content (4.5 ± 0.71) %, moisture (25.1±0.82) %, Fat (7.0 ± 1.41)%, total solid (23.2+ 1.13)%, protein (1.21 ± 0.07)% and carbohydrate (36.8 ± 1.13)% while TS8D are ash content (2.0 + 0.00%, moisture (23.27 ± 0.81%, Fat (9.0 ± 1.41)%, total solid (18.4 ± 0.49%, protein (0.66 ± 0.01)% and carbohydrate (41.8 ± 0.35)%. The cyanide content for FHT was 32.86 ± 0.13 mg/kg while TS4D and TS8D are 30.17 ± 0.40 mg/kg and 27.9 ± 2.43 mg/kg respectively. In conclusion, the postharvest storage of bitter cassava had minimal effects on the proximate composition while the cyanide content reduced significantly with storage. This implies that postharvest storage before processing of cassava tubers might be a cheap way of reducing cyanogenic glycosides in bitter cassava.
