The Difference Between White And Black Watermelon Seeds
By SYLVIA TOMCZAK
Considering that Americans eat about 14 pounds of watermelon per capita every year, chances are that you have cut into a watermelon at some point and noticed either black seeds, white seeds, or a mix of both. The thin, white flecks found in watermelon are actually empty seed coats that indicate a seed didn't fully mature.
Although common in seeded watermelon, white seeds appear in seedless varieties — just at a lesser volume. As a result of cross-breeding traits, these undeveloped seedlings aren't capable of reproducing like the matured and fertile black seeds.
Although many spit them out, all watermelon seeds are perfectly safe to eat. You could roast them to take advantage of their protein, amino acids, B vitamins, and magnesium, or you could even use them to make watermelon seed butter.
