Abstract

fetched live from OpenAlex

Oil migration from a 60:40 (w/w) mixture of peanut oil and chemically interesterified and hydrogenated palm oil (IHPO) was a strong function of the cooling rate experienced by the fat mixture during crystallization, namely, 0.4, 1.2, and 6.0 °C/min. The relative oil loss determined gravimetrically was inversely proportional to the cooling rate. Oil loss was also inversely related to the storage modulus (G‘) and the yield force of the fat. After 1 day storage at 20 °C, the start of the oil loss studies, the composition and polymorphism of the fat crystals crystallized at different rates were similar, as judged by differential scanning calorimetry and powder X-ray diffraction. Crystals were in the same β‘ modification and had similar peak melting temperatures. Microstructure, on the other hand, was profoundly affected by the cooling rate: average crystal size decreased from 8.2 μm (at 0.4 °C/min) to 3.9 μm (at 6.0 °C/min). Using Darcy's Law, it was possible to calculate permeability coefficients using the structural parameters obtained in this work. Decreases in permeability coefficient as a function of increasing cooling rate were mainly related to decreases in crystal size.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
