00:00 The world of food is a real rainbow of colors.
00:03 However, among this diversity, blue is singularly absent.
00:08 And for what reason?
00:09 This would mainly be due to the biochemistry of plants.
00:12 Blue in the plant world is produced by anthocyanins,
00:16 pigments that can cover blue under certain pH conditions.
00:21 However, these conditions are relatively rare in the plant world.
00:25 In addition, blue is not a particularly advantageous color for the reproduction or survival of the plant.
00:31 Indeed, it does not attract pollinators in the same way as the brighter colors,
00:35 such as red or yellow, which could explain its rarity.
00:38 Therefore, naturally blue foods are a real curiosity on our plates.
