Storage Stability of Selected Vegetable Purees in High Barrier Pouches Processed With Pressure‐Assisted Thermal Sterilization
Bibliographic record
Abstract
ABSTRACT This study evaluated the stability of physicochemical properties, including the enzymatic activity of polyphenol oxidase (PPO) and the concentration of natural pigments, of three vegetable purees packaged in high barrier pouches after pressure‐assisted thermal sterilization (PATS) and 6 months storage. The red beetroot, red cabbage, and carrot purees sealed in a high‐barrier polymeric pouch were subjected to a PATS treatment at an operating pressure of 600 MPa and a starting vessel temperature of 90°C for a 5 min process. After PATS, the residual activities of PPO ranged from non‐detectable to 8.1%. A total color difference (ΔE) in different purees varied between 4.23 and 5.53. The PATS treatment caused significant degradation in the content of betalains in the beet puree, while both anthocyanins in the cabbage puree and beta‐carotene in the carrot puree exhibited a higher retention. During the 6 months of storage, cabbage puree showed a higher ΔE value and PPO residual activities than beetroot and carrot purees. Both anthocyanins and betalains experienced significant degradation, but beta‐carotene had a high storage stability.

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.
