Abstract

fetched live from OpenAlex

The microbial shelf-life of carbonated beer can be extended after processing by pulsed electric fields (PEFs). Being a non-thermal preservation method, the fresh-like taste and original nutritional values are better retained than with the conventional thermal pasteurization. However, due to the flow of current, metal ions will be released from the electrodes during the processing. The presence of these ions in the PEF-processed beer accelerates its aging and may affect the organoleptic stability. Hence, this study evaluates the metal ions released during PEF processing under different test conditions. It has been found that the amounts of iron ions released under the conditions tested are well below the iron concentration found in many consumable products in the market. The effect of processing zone temperature in the range 1-30 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</sup> C on the concentration of metal ions is not significant; thus exploring the synergistic effect of both PEF and temperature on microbial killing is possible.

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.
