USING INGREDIENTS IN PPM (Parts per Million)

1 / 1,000,000  =  1 PPM or 0.000001

For our purposes 100 grams = 100 milliliters
1% solutions: = 1g / 100g solvent =  1 / 100 = 0.01g/g solvent 

ppm solutions
1 gram of a 1% solution in 100 g water = 0.01g/100g = 0.000100 = 100 ppm
0.1 gram of a 1% solution in 100 g water = 0.001g/100g = 0.000010 = 10 ppm

To make a 1 ppm taste solution, add 10 grams of a 10 ppm solution to 90 grams  of water
Make successive dilutions to make 0.1 ppm solutions, etc.

Determining ppm usage of Ingredients in Flavors
Determine actual usage of ingredient in formula 
1) Example:  Using 0.2 grams of a 10% ingredient solution is actually 0.02 grams
2) Divide actual usage of ingredients by flavor total.
    Example in a 10 gram formula 0.02 / 10 = .002g/gram of flavor

3) Multiply .002 by use level of flavor. Example if flavor was used at 0.1%,
    0.002 X 0.1% = 0.000002 or 2 ppm

For 10 gram formulas, the use of 10% solutions provide ppm’s in the range of 1 – 10
Example: 0.5 grams of a 10% solution of ethyl acetate results in 5 ppm consumed, if the flavor is used at 0.1%. 

For 10 gram formulas, the use of 1% solutions provide ppm’s in the range of 0.1 – 0.9
Example: 0.5 grams of a 1% solution of ethyl acetate results in 0.5 ppm consumed, if the flavor is used at 0.1%.
0.5 X 1% = .005 / 10 = .0005 X 0.1% = .0000005 = 0.5 ppm
