Extraction of Tartrazine from Food Colorants by PEG/Salt Aqueous Two-Phase System
Bibliographic record
Abstract
An aqueous two-phase system(ATPS)is presented with polyethylene glycol(PEG)and salt for the extraction of tartrazine in this paper.The extraction of tartrazine in ATPS is investigated.Concentration of(NH4)2SO4and PEG,pH value and other factors are evaluated to determine their effects on the extraction yield of tartrazine.The results show that the extraction yield strongly depends on the concentration of PEG and(NH4)2SO4.A high extraction yield around 98%is achieved with the following parameters:(NH4)2SO415%,PEG2000 18%,pH 6.It is found that the extraction yield undepends on the additional salt,but the presence of surfactant influences the extraction yield evidently.

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.
