I. Summary of the Method

This method is a proprietary method for determining the lactose in low lactose or lactose-free products. The measurement of lactose involves an enzymatic electrochemical biosensor (BIOMILK 300 LAC). This biosensor incorporates a biochemical sensing element and a transducer system that can relates the concentration of lactose to a measurable signal. The analysis is performed directly over the aqueous solution. The addition of the sample (or the lactose) in the solution causes sequential redox reactions that involve a release of electrons proportional to the concentration of the lactose. Such the concentration of the lactose is determined. The applicability of the method meets the SMPR requirement. Sample type include milk, yogurt, cream, soft cheese, infant formula, Café latte, and protein shake.

II. Review of the Method Only 1. Does the applicability of the method support the applicability of the SMPR? If not, please explain what is missing. 2. Does the analytical technique(s) used in the method meet the SMPR? If not, please specify how it differs from what is stated in the SMPR. 3. Are the definitions specified in the SMPR used and applied appropriately in the method? If no, please indicate how the terms are used.

There is no requirement of any specific technique in the SMPR. So, it is a yes.

Yes
