Abstract

fetched live from OpenAlex

Ultrasonic assisted extraction was employed to extract oligosaccharides from longan fruit pericarp (OLFP). A Box-Behnken design was applied to investigate the effects of ultrasonic temperature (30-70 degrees C), power (120-300 W), and time (10-50 min) on OLFP recovery. The model showed a good agreement with the experimental results on the basis of R(2) of 0.9655 and P-value <0.05. From response surface plots, ultrasonic power, time, and temperature exhibited independent and interactive effects on OLFP recovery. The optimal conditions to obtain the highest OLFP recovery were determined to be 13 min, 121 W, and 65 degrees C. Gas chromatography analysis indicated that purified OLFP comprised Gal (71.5%), Glc (24.6%), and GalA (3.9%). The analysis of glycosidic linkages showed that the backbone consisted of -->3)-Gal-(1-->, -->6)-Gal-(1-->, Glc-(1--> and -->3)-GalA-(1--> with a molar proportion of 13:5:6:1. Furthermore, the 1,1-diphenyl-2-picryldydrazyl (DPPH) and superoxide anion radical scavenging assays showed that OLFP exhibited strong antioxidant activities in a dose-dependent manner.

Full frame distilled prediction

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.
