[6.2] omitting subclause 5(3) and substituting
"(3) To calculate the steviol equivalent levels for a steviol glycoside, the following equation is used -
[SE] = \sum\left([SG] \times CF\right)
where -
[SE] = concentration as steviol equivalents
[SG] = concentration of individual steviol glycoside
CF = Conversion Factor as listed in the Table for the corresponding steviol glycoside
Table to subclause 5(3)
| Column 1 | Column 2 |
|---|---|
| Steviol glycoside | Conversion factor |
| Dulcoside A | 0.40 |
| Rebaudioside A | 0.33 |
| Rebaudioside B | 0.40 |
| Rebaudioside C | 0.33 |
| Rebaudioside D | 0.28 |
| Rebaudioside F | 0.34 |
| Rubusoside | 0.50 |
| Steviol | 1.00 |
| Steviolbioside | 0.50 |
| Stevioside | 0.40 |
Examples:
Example 1 – Calculating steviol equivalents for a single glycoside
A preparation of 100 mg/kg of Rebaudioside B contains 100 x 0.40 = 40 mg/kg steviol equivalents.
Example 2 – Calculating steviol equivalents for a mixture of glycosides
For a preparation containing 100 mg/kg of a mixture of 90% Stevioside, 5% Rebaudioside B and 5% Rebaudioside A, the steviol equivalent is
[SE] = \left(\frac{90}{100} \times 100 \frac{mg}{kg} \times 0.4\right) + \left(\frac{5}{100} \times 100 \frac{mg}{kg} \times 0.4\right) + \left(\frac{5}{100} \times 100 \frac{mg}{kg} \times 0.33\right)
= (0.9 \times 0.4 + 0.05 \times 0.40 + 0.05 \times 0.33) \times 100 \frac{mg}{kg}
= 39.7 \frac{mg}{kg}
Examples:
Example 3 – Calculating the maximum permitted level (MPL) of a steviol glycoside preparation
To calculate the MPL of a steviol glycoside preparation which contains 90% Stevioside, 5% Rebaudioside B and 5% Rebaudioside A, in a food where the permission is 160 mg/kg (steviol equivalents).
[SE] = 160 \frac{mg}{kg}
[Stevioside] = 0.9 \times MPL
[Rebaudioside B] = 0.05 \times MPL
[Rebaudioside A] = 0.05 \times MPL
Substituting into the equation
[SE] = \sum\left([SG] \times CF\right)
We get:
160 \frac{mg}{kg} = (0.9 \times MPL \times 0.4) + (0.05 \times MPL \times 0.4) + (0.05 \times MPL \times 0.33)
Therefore,
MPL = \frac{160}{0.9 \times 0.4 + 0.05 \times 0.4 + 0.05 \times 0.33} \frac{mg}{kg}
MPL = 403.5 \frac{mg}{kg}
