In the quest to keep caramel apples fresh for as long as
possible, Joe Sofia from Cargill Cocoa & Chocolate investigates the
effectiveness of a popular preservation method: the lemon juice trick. This
method, which suggests dipping the wooden sticks in lemon juice before use, is
believed to extend the shelf life of these sweet treats. But does it really
work?
The shelf life of a caramel apple is typically only one to
two weeks. The primary issue arises at the point where the stick is inserted
into the apple. Over time, this area turns brown and becomes unappetizing due
to enzymatic browning—a biochemical reaction triggered when apple flesh is
exposed to oxygen. This phenomenon is what often limits the apple's appeal and
shelf life.
Variables Affecting the Rate of Browning:
Temperature: Temperature plays a
significant role; refrigerating caramel apples can slow down this process.
Apple variety: the
variety of apple used can affect how quickly it browns, as different types have
varying compositions
Without the stick, the shelf life of caramel apples could
be considerably longer, since the caramel, nuts, and chocolate used in their
preparation generally have a much longer shelf life.
Does the lemon juice trick really work?
The lemon juice trick involves soaking the wooden sticks in
lemon juice before inserting them into the apples. It has been suggested that
this trick helps to preserve the apples by reducing browning at the stick
insertion point. However, Joe Sofia's testing did not reveal a significant
difference between apples with lemon-soaked sticks and those with unsoaked
sticks. After a week, both types of sticks—whether soaked in lemon juice or
not—showed similar browning around the insertion point.
Given the limited impact of the lemon juice trick, another
approach to extending the shelf life of caramel apples is to forgo the stick
altogether. By using large dipping forks, beaker tongs, or scissor-style tongs
to dip the apples in caramel, candy makers can avoid the browning issue
associated with the stick. While this method may slow down the dipping process,
it might be a worthwhile trade-off for those focused on maximizing freshness.
For customer convenience, sticks could still be provided separately for those
who prefer them.
In conclusion, while the lemon juice trick does not
significantly extend the shelf life of caramel apples, exploring alternative
methods like going stickless could offer a practical solution for preserving
these delightful treats.
