Abstract
Cashew apples and kernels from sixteen high-yielding varieties were chemically characterized. Protein, starch, amino acids and sodium contents in cashew kernels did not vary significantly among the high-yielding varieties. Reducing sugar content in the kernel was negligible compared to total sugar. Ascorbic acid, amino acid, phenol and tannin contents in cashew apple showed a significant variation among high-yielding varieties. Non-reducing sugar content in cashew apples was negligible. Varieties M 6/1, Bla 256-1, M 10/4 and M 44/3 appeared to be better for apple juice extraction because of their low tannin content. No varietal difference was noticed with respect to qualitative composition of sugars, organic acids and phenols.
