Microbiological and chemical characterisations of organic and conventional date pastes (Phoenix dactylifera L.) from Tunisia
Bibliographic record
Abstract
Chemical and microbiological properties of organic and conventional date pastes produced from the Deglet Nour cultivar were investigated. Significant differences were observed in water content, sugar profiles, and pH among the date pastes. The low moisture and the high acidity of organic date paste were two important positive attributes for its storage and potential manufacturing uses. Before pasteurisation, moulds CFU’s of the organic paste was significantly ( P < 0.01 ) lower than those of the conventional one but no significant differences were observed for yeasts, coliforms and the total aerobic flora among the two date pastes. Considerable interest has developed on the preservation of conventional date paste by the use of natural additives such as Juniperus phoenicea and olive oil (conditioned paste). At a given mixture of Juniperus and olive oil and after pasteurisation, mould CFU’s were reduced by 95% ( P < 0.01 ) whereas the reduction was only 84% for the yeast populations, after 45 days at 25 °C.

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.
