Influence of Drying Temperature of Jambu Leaves (Acmella Oleracea) in a Spray Dryer
Bibliographic record
Abstract
Jambu (Acmella oleracea), also known as Pará cress, is a plant widely used in cuisine and traditional medicine, standing out for causing a tingling sensation in the mouth due to the presence of the compound spilanthol. This research aimed to analyze the effects of inlet temperature on the drying process of Jambu leaf extract using a spray dryer. The experiment was conducted at temperatures of 110°C and 140°C, respectively. The results indicated that the higher temperature (140°C) provided a greater powder yield (40.10%) compared to 110°C (30.94%). Water activity remained below 0.3 in both conditions, indicating microbiological stability. The color of the powder showed no significant variations, maintaining favorable visual characteristics. The bulk density was lower at 140°C (0.22 g.cm-³) compared to 110°C (0.39 g.cm-³). Morphological analysis revealed that higher temperature resulted in more spherical and regular particles.

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.
