Abstract
This study evaluated the effect of maturity
length on the nutritional and antinutrient composition of local cassava (Manihot
esculenta Crantz). Fresh cassava roots were harvested at three maturity
stages (CS1–CS3) and processed into samples for analysis. Proximate composition
(moisture, crude protein, fat, fibre, ash, and carbohydrate by difference) was
determined using standard AOAC methods. Mineral elements were analyzed using
flame photometry and atomic absorption spectrophotometry, while phosphorus was
determined colorimetrically. Vitamins (B-complex, A, and C) were quantified
using spectrophotometric methods, and antinutrients (phytate, oxalate, tannin,
saponin, total polyphenols, and hydrogen cyanide) were determined using
established analytical procedures. All analyses were conducted in duplicate,
and data were subjected to statistical analysis to determine significant
differences at p > 0.05. Results showed no significant differences (p >
0.05) across all parameters, indicating that maturity stage had minimal
influence on cassava composition. Proximate analysis confirmed cassava as a
carbohydrate-rich crop (28.45–28.51%) with high moisture content (66.52–66.61%)
but low protein (1.48–1.69%) and fat (0.41–0.47%). Mineral and vitamin contents
were generally low but stable across samples. Antinutrients such as phytate
(0.083–0.089%) and oxalate (0.032–0.037%) were present in low amounts, while
hydrogen cyanide levels (257.31–257.36 mg/kg) were relatively high. In
conclusion, cassava maturity stage does not significantly affect its
nutritional or antinutritional composition. However, its low nutrient density
and cyanide content emphasize the need for proper processing and dietary
diversification to ensure safety and improved nutritional quality.
