Information: Calculating the percentage of dairy in a product

Effective 8 August 2019 to 8 October 2021

Calculating the percentage of dairy in a product

  1. Dairy must be calculated by dry weight of the product. Any added water must be removed prior to calculating the percentage of dairy in the product.

  2. Lactose (and its derivatives), ghee and chocolate do not contribute to the percentage of dairy, provided that the final product is commercially prepared and packaged.

  3. The dairy component of the entire product should be calculated, rather than calculating the percentage of dairy in each individual component.

Formula for calculating dry weight of dairy in product

Dairy by dry weight = (Dairy x 100) / (100 – Water)

Example calculation

Product contains the following ingredients (totalling 100%):
Whey powder 40%
Skim milk 25%
Lactose 15%
Grape extract 5%
Water 15%

Add all dairy ingredients (excluding lactose)
40+25 = 65

Remove added water from product
(100-15) = 85

Dairy by dry weight = (65 x 100) / 85
The percentage of dairy by dry weight in the product is 76.47%
