Phenolic Compounds and Polyamines in Grape-Derived Beverages
Bibliographic record
Abstract
Isotopic analyses and chromatographic analysis (phenolic compounds and biogenic amines), can be applied to investigate the functional and nutritional quality in different grape juices and wines. These beverages when produced exclusively from grapes contain bioactive compounds. In this way, the isotopic analysis, as well as the determination of phenolic compounds and biogenic amines were performed with the aim of verify the functional quality of juices and wines produced with Vitis vinifera and Vitis labrusca grapes. The samples that were analyzed consisted of four whole juices, two nectars, two V. vinifera wines, and two V. labrusca wines. Regarding the isotopic analyses, only one nectar, among the beverages studied, presented the addition of sugar from C4 plants. Wines from V. vinifera showed the highest content of biogenic amines and phenols; whereas, the highest content of anthocyanins were found in V. labrusca. The levels of biogenic amines and phenolic compounds were variable between samples, and recommendations for consumers should be made considering several conditions, such as physiological state, age, consumption, among others. Anthocyanins and biogenic amines, as well as isotopic analyses, can be applied as tools to measure the quality of grape derived beverages.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
