The Role of Emulsifiers on the Crystallization of Cocoa Butter and Cocoa Butter-sugar Blends
Bibliographic record
Abstract
The crystallization of cocoa butter and 1:1 cocoa butter-sugar blends containing 2 wt% emulsifier was investigated. The emulsifiers studied were soy lecithin, polyglycerol polyricinoleate (PGPR), citric acid esters of mono- and diglycerides (CITREM) and ammonium phosphatides (YN). Lecithin, CITREM and YN enhanced nucleation and growth events substantially, however, had minimal effects on the form IV-to-V transition and enthalpy. PGPR showed a modest enhancement of crystallization kinetics but promoted the formation of form V polymorph similar to that of canola and castor oil. In the presence of sugar, emulsifiers were no longer able to influence nucleation and growth. Sugar also hindered the form IV-to-V transition in the presence of both emulsifier and oil. Overall, results showed that emulsifiers may be used to tune the isothermal crystallization of cocoa butter, though this depends on the presence of dispersed sugar.

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.
