Updated by SFA Where two or more permitted Class II chemical preservatives are used in the same product, the sum of their respective percentages must not exceed 100%, as stipulated under Regulation 19(3)(b)(ii) of the Food Regulations.
The percentage use level for each Class II chemical preservative in an admixture may be calculated using the formula below:
[Amount of permitted Class II chemical preservative added (ppm) / Maximum permitted level of Class II chemical preservative (ppm)] x 100% = Y
Example: An admixture of permitted Class II Chemical Preservatives, (Chemical X + Chemical Y + ….) when added to the same food product must be less than 100%
Y1 + Y2 + Y3 +… ≤100% Contact us
Can I add more than one Class II chemical preservative to the same product?
