Table 4 NOVA analysis-based identification of refinement measures
No. | Ambiguities/inaccuracies | NOVA-intrinsic sources | Suggested measures |
---|---|---|---|
1 | Confusion of formulation and processing | S1. Discrepancy between nature of classification parameters and the designation of classes S2. Vague and over-inclusive definition of UPF S3. No clear focus on nutrition value (e.g for specific “UPF-ingredients”) | M1. Clear definition, differentiation & separation of formulation & processing M2. Reference to nutrition value as 1st target property for M1 measures M3. In future: consider formulation & processing parameter(s) impact on palatability & satiation kinetics aspects as 2nd/3rd target properties (including aspects of e.g.: matrix volume, water & air content, H2O-binding in modified NRF*) |
2 | Missing quantification of formulation and processing parameters | S4. Restriction to the qualitative characterization of food products (no thresholds for formulation, no levels of formulation and processing) | M4. quantifying levels of formulation (i.e. NRF*x.y.z) & processing (i.e. ΔNRF*x.y.z) M5. enabling coupling of F- & P-parameters (e.g. FPFIN) to simplify M6. in the future: consideration of (i) matrix volume & water/air fractions incl. their change by processing (e.g drying/aeration/gelling); (ii) gastro-intestinal rheology |
3 | Weak evidence base (observational studies) for correlations between food classes & obesity/CNND disease risks | S5. No clear control of other risk factors for weight gain S6. Risk of misclassification (i.e. single ingredient dependency for UPF) | M7. Base correlations with obesity & health risks on quantified F&P parameters taking nutrition value (& prospectively satiation kinetics) into account |
