Abstract

fetched live from OpenAlex

There are several definitions of a clean label ranging from broad clean label claims identifying the type of ingredient (i.e., organic, non-GMO, unfamiliar/unrecognizable ingredients) to strict clean label claims identifying the number of ingredients (i.e., shortening of ingredients lists), both of which can appear as Front of Package (FOP) labeling. Therefore, the following research examines what Canadian consumers value in a clean label, how Canadian consumer attitudes toward clean labels could impact the demand for pea-based proteins, and assesses how pea-based burgers compete against hybrid and beef burgers. The study relied on nationally collected data through an online survey to explore the objectives. The survey was composed of five sections featuring screener questions, discrete choice experiment (DCE), general food purchases, protein choices, and demographics, and analyzed using Multinomial Logit, Mixed Multinomial Logit, and Latent Class models. The analysis revealed Canadian consumers ranked beef burger patties (60%) as the preferred choice, hybrid burger patties (22%) as the second most preferred choice, pea-based burger patties (18%) as the least preferred burger choice, with the rest selecting no purchase (1%). When exploring burger patty heterogeneity for clean label claims, individuals choosing pea-based burgers exhibited notably different taste preferences for the ingredient list length, exhibiting similar WTP between the organic attribute and shortened ingredient lists. Lastly, the respondents who were less likely to choose pea-based proteins, about 85% of individuals, valued stricter clean labels more than broad clean labels, perceiving that a reduced ingredients list signaled increased product naturalness, nutrition, and did not decrease taste. Concluding reduced ingredients list was the most significant clean label definition within the study.

Not 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.
