Abstract

fetched live from OpenAlex

Chocolate, reengineered If you go to Alejandro Marangoni’s house for a meal, you might be treated to an experiment. The University of Guelph food scientist went through a phase of feeding his children pancakes made with as much fiber as they could stomach. These days Marangoni might treat a guest to something sweeter: a special chocolate engineered to be easier to make. Cocoa butter crystals can take six forms, one of which makes for chocolate with the ideal glossiness, snap, and melting behavior. Chocolatiers carefully temper chocolate, melting and cooling it until it looks and feels right. Chocolate becomes glossy and has just the right viscosity when Form V cocoa butter crystals dominate, and other polymorphs have melted away. Commercial chocolate makers monitor the process by temperature. Even with great attention to detail, the process is difficult to control. The primary components of cocoa butter fat crystals are triglycerides. Marangoni

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.
