What does it mean when watermelon is white inside?
If your watermelon is white inside, then that makes it a white watermelon. As its name so aptly indicates, white watermelon is a variety of sweet watermelon with white flesh. It’s the same botanical fruit as red watermelon, just white inside.
The white flesh color actually means the watermelon lacks pigments, hence the discoloration. Red watermelon is red inside thanks to a high content of the carotene lycopene. Yellow watermelon is yellow inside as a result of a higher content of xanthophylls such as lutein, neoxanthin, violaxanthin and neochrome. While orange watermelon is orange thanks to a high content of carotenes such as beta-carotene. Lacking these natural pigments completely or almost completely, white watermelon develops little to not color inside.
