Have you ever been to the grocery store and seen oranges on
display that are so incredibly bright orange that they almost looked fake? I
have. Sometimes they’re also very shiny, or have skins that seem very thick and
leathery.
They certainly are beautiful, but maybe you felt a bit puzzled
by these fruit. Did it almost seem like they were “too good to be true,” or might
be intended more to look at than to eat?

Dyeing to Look Pretty
If you were suspicious that something not so natural could be
involved here, you could be right. Though few people realize it, some growers
use artificial dye on the outside of their oranges.
The dye used, FD&C red #2, can be found in various foods we
buy at the supermarket and is not thought to be harmful. You should see (by
law) an indication somewhere on the package that dyeing has occurred.
However, many of us wouldn’t expect to find synthetic dyes
in fresh fruit like oranges. And a lot of people prefer to avoid artificial
dyes due to allergies or sensitivities. That’s why, at Florida Fruit
Shippers, we never sell fruit that has been dyed.
Why Dye?
So, why do some growers choose to dye their citrus? It’s
actually pretty simple. As we have explained elsewhere on this blog, oranges don’t
have to be fully orange (or even orange at all!) to be ripe. The fruit turns
color due to cool temperatures, not as an indicator of ripeness.

Consumers, of course, may not know this! If they see green
or greenish citrus at market, they could pass it by. After all, we do tend to “eat”
with our eyes. On the whole, people choose produce that is the most intensely
colored, even if that has been done artificially. And large commercial growers
selling to grocery stores don’t have the luxury of hand selecting each piece
of fruit, like we do here at FFS.
(Did you know that artificial food dyes are illegal in many
countries? It’s true! Another
interesting fact is that it is possible to dye fabric with orange peels. Yes, we mean the kind that haven’t been given
an artificial color-boost! Typically the fruit is bright enough to leave its
“mark” behind in natural cloth.)
The Real Way to Judge Ripeness
So, since color may not be a reliable indicator, how growers
know whether fruit is ripe? We have lots of ways! In general, as fruit
specialists, we have a good idea when the fruit “should be” ready for harvest.
But because we want to make sure it’s at its peak before we pick, we use some
special equipment to check the balance of acidity and sugar levels in the
fruit. The process is pretty scientific, though naturally, we also rely on our
own judgement and expertise as well.
