How the Food Ingredients Scanner Reads Order of Predominance
Under global labeling mandates established by the US FDA (21 CFR 101.4), the European Union (FIC Regulation 1169/2011), and China (GB 7718), packaged food ingredients must be listed in descending order of predominance by weight at the time of formulation. When reviewing a label, the first three ingredients generally constitute the overwhelming majority (70% to 85%) of total food mass.
CleanLabel’s AI food ingredients scanner analyzes positional hierarchy to determine whether a product's primary foundation consists of wholesome, unadulterated raw ingredients (such as whole cow's milk, whole grain oats, or fresh fruit puree) or ultra-processed filler ingredients like high-fructose corn syrup, modified food starches, and hydrogenated vegetable oils.

Clean Label 4-Tier Health Index: Grades A, B, C, and D
To assist shoppers in making instant, confident dietary choices, our algorithm categorizes scanned items into four evidence-based health tiers. Detailed criteria can be examined in our clean label rating methodology:
- Grade A (Pure & Natural · Clean Label): Completely free of artificial food additives, chemical preservatives, synthetic dyes, and artificial sweeteners. Formulated exclusively with whole agricultural foods, gentle botanical extracts, and essential vitamins or minerals. Examples include 100% cold-brewed green tea, organic rolled oats, and pure Greek yogurt.
- Grade B (Lightly Processed · Safe Processing Aids): Contains minimal, technologically indispensable processing aids with comprehensive safety profiles, such as sodium bicarbonate (baking soda), sunflower lecithin (natural emulsifier), or citric acid (natural fruit acid). Zero synthetic azo colorants.
- Grade C (Moderately Processed · Common Dietary Concerns): Contains conventional industrial preservatives (e.g., potassium sorbate, sodium benzoate) or significant quantities of added refined sugars and maltodextrin. Parents and health-conscious consumers are encouraged to moderate consumption frequency. Learn more in our guide on kids yogurt and snacks.
- Grade D (Ultra-Processed · Multi-Additive Stacking): Characterized by extensive chemical additive stacking (more than 5 functional additives), including artificial food dyes (Red 40, Yellow 5), intense synthetic sweeteners (aspartame, acesulfame potassium, sucralose), flavor enhancers (monosodium glutamate E621, disodium ribonucleotides), and hydrogenated vegetable fats.
Cross-Jurisdiction Comparison: China GB 2760-2024 vs. US FDA Standards
International food standards reflect different regulatory philosophies. For example, under the newly promulgated China GB 2760-2024 (Standards for Uses of Food Additives), sodium dehydroacetate (脱氢乙酸钠)—a widely used preservative—has been completely banned from bakery products, bread, and pastries due to long-term cumulative toxicity risks. In contrast, under US FDA CFR Title 21 regulations, chemical preservatives and food dyes remain under active re-evaluation, as seen with the recent California Food Safety Act (AB 418) restricting Red Dye No. 3 and potassium bromate.
