Crystallization behaviors of diacylglycerol and triacylglycerol prepared by enzymatic catalysis
Bibliographic record
Abstract
Lipozyme RM IM was used as catalyst in the synthesis of diacylglycerol( DAG) by the transesterification of soybean oil mixed with palm stearin( melting point 45 ℃) and monoacylglycerol( MAG,prepared by soybean oil,palm stearin and glycerol),and in the synthesis of triacylglycerol( TAG) by the transesterification of soybean oil and palm stearin. Crystallization and melting behaviors of the DAG,TAG and TAG added with different proportions( 10%,30%,50% and 70%) of DAG were determined by differential scanning calorimetry( DSC),pulsed- nuclear magnetic resonance( p NMR) and polarized microscopy. The results showed that with similar fatty acid compositions,the initial crystallization temperature( 28. 14 ℃) and melting point( 48. 26 ℃) of DAG was higher than the initial crystallization temperature( 8. 51 ℃) and melting point( 30. 58 ℃) of TAG. By adding 50% and 70% of DAG,the melting point and initial crystallization temperature of TAG increased. In comparison,adding 10% and 30% of DAG had less impact on the crystallization of TAG. The solid fat content of the mixture gradually improved with the increase of addition proportion of DAG. Acicular crystals in the mixtures added with 50% and 70% of DAG were found near melting points.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
