Evaluation of strawberries dried by radio frequency energy
Bibliographic record
Abstract
Dielectric processing has recently attracted attention in both agriculture research and industry as an efficient heating/drying method. Dielectric processing includes drying by radio frequency (RF) and microwave drying (MW). The characteristics of RF dried strawberries were evaluated and compared to hot air drying (AD), freeze-drying (FD) and MW drying. Our results showed that dielectric drying was superior in terms of drying rate. The total drying time of MW and RF were 40 and 55 min, respectively, compared to 100 and 1,320 min for AD and FD, respectively. Compared to MW drying, RF drying offered better uniformity of temperature distribution and energy transformation. RF dried strawberries also had superior color compared to AD and MW, as well as greater retention of carotenoid, anthocyanins and total phenolics, the quality of RF dried samples was close to FD samples. SEM photos indicated RF dried samples showed better quality (smoother surface) than MW. Flavor analysis showed that all drying methods reduced aromatic substances.

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.
