Watermelon (Citrullus vulgaris) and grape (Vitis vinifera) seeds constituted 1.9 and 1.6% of fresh fruit. The melon seed on a dry weight basis consisted of testa 53.6 and kernel 46.4%. The crude protein, fat and fibre contents were 16.4, 23.1 and 47.7% for melon and 8.2, 14.0 and 38.6% for grape in DM. Both seeds had significant amounts of Ca, Mg, P and K. The unsaturated fatty acid content was 76.1% for melon and 88.6% for grape seed oil. The main fatty acid in both seeds was linoleic acid. The iodine value, saponification number and acid value were 116, 248, 0.97 and 132, 194, 1.59, respectively. The oils were edible and the meals could be used for animal feeds. The seed cake proteins had a lower content of essential amino acids than had egg protein.
