Understanding Neutralizing Value
and Dough Rate of Reaction
Description
Neutralizing Value (NV) is the measure of available acidity
in leavening acids. The value is used to determine the
amount of acid or acids needed so when combined
with sodium bicarbonate, it produces a neutral pH. NV
represents the number of parts of sodium bicarbonate
that can be neutralized by 100 parts of the leavening acid.

Applying Neutralizing Values
The formula to figure acid amounts
Amount of Bicarb x 100 = Amount of acid to
Neutralizing Value (NV) neutralize the bicarb
How much acid to use
Example: A formula calls for 2.5 grams of bicarb.
How much V-90 (NV = 83) is needed
2.5 grams bicarb/83 (NV of V-90) x 100 = 3.01
3.01 grams V-90 are needed
Using two acids:
Example: A formula calls for 3.74 grams of bicarb
and a blend of 80/20 BP Pyro/V-90.
a. Find average NV by percentage:
80% of 72 = 57.6
20% of 83 = 16.6
Average NV = 74.2
b. Determine amount of blend using formula:
3.74 x 100 = 5.04 grams acid blend
74.2
c. Calculate % of each acid to use:
5.04 x 80% = 4.03 grams BP Pyro
5.04 x 20% = 1.01 grams V-90

Dough Rate of Reaction (DRR)
The measurement of the speed of reactivity of the
leavening acid in a dough mixture. The test for this
is performed by measuring the amount of carbon
dioxide released over a period of time at a certain
temperature (27°C is typically used). This Rate
of Reaction is controlled by the leavening acid’s
physical and chemical characteristics. The results
are expressed in percentage of CO 2 .
