Flavour over preservation: a label analysis examining the use of food additives in animal-based foods marketed in Brazil
Bibliographic record
Abstract
Packaging animal-based foods often necessitates the use of additives for preservation. No study has yet focused on the usage of food additives across different animal-based foods. This study aimed to examine food additives declared on labels of animal-based foods (n = 1702) sold in Brazil. Data was collected through a census of food labels conducted in a supermarket in 2020. The number and prevalence of additives were determined by functional class, food group, and food subgroup. Additives were identified in 71% of the analysed labels. Excluding fresh foods, the prevalence of additives was 84%. The food groups with the highest prevalence of additives were dairy products (89%), ready-to-eat dishes (88%), and animal fats (60%). A total of 240 different food additives were identified, with a median of three additives per food. The most reported functional classes across all food groups were flavourings (20%), stabilisers (19%), preservatives (14%), and colourings (9%). These results showed that additives were primarily used for sensory reasons, such as altering taste, smell, colour, and texture, rather than for preservation purposes. These findings may promote discussions and a review of regulations on the use of food additives in animal-based foods.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
