Each product formulation has its own peculiarities regarding the way the product
absorbs carbonation and the way it releases carbonation.
BRIX Affects Overrun
Sugar in carbonated drinks is like anti-freeze in water. The higher the BRIX, the
greater the resistance of the product to freezing. Conversly, in products with lower
BRIX, freezing takes place at higher termperatures than for high-BRIX products.
Thus, BRIX affects overrun because the amount of sugar in a drink has a direct
bearing on the product’s freezing characteristics.
Low Dispensing Volume
Affects Overrun
When a unit sits idle fo a period of time with no drinks being dispensed, CO2 gas
in the system takes a “set”. When the first few drinks are drawn off after an idle
period, CO
2 gas has less tendancy to break out as the drink is dispensed. The
result is that these first drinks hav less overrun than drinks dispensed during peak-
use periods.
Carbonation Level in Liq-
uid Product Affects Over-
run
The higher the specific carbonation level in a given product, the greater the
potential for carbonation breakout in frozen carbonated form of that drink. For
example, drinks with 3.0 volume of carbonation have more gass breakout in
frozen carbonated form and more overrun than drinks that contain 2.0 volumes of
CO
2 gas.
Freezing Affects Overrun
Freezing causes approximately a 5-7 percent expansion in dispensed frozen
carbonated drinks. The degree of freezing is limited because the finished drink is
intended to be sipped through a straw. This is not possible if the product is too
“solid”.
