Effect of Sodium Periodate Oxidation of Cassava Starch on Grease Resistance and Waterproofing of Food Wrapping Paper
Bibliographic record
Abstract
Developing biomass-based packaging materials to replace plastic packaging materials is an inevitable trend for the food packaging area. Here, dialdehyde starch (DAS) was synthesized by oxidation of cassava starch using sodium periodate as the oxidizing agent, and then the waterproof and oil-resistant wrapping paper was prepared by coating DAS onto the surface of Kraft paper. The effect of the aldehyde content on the barrier properties of dialdehyde starch film and coated Kraft paper was studied. The results showed that the coated Kraft paper with 5 wt % DAS (aldehyde content of 98%) had the best comprehensive water and oil resistance, with an oil resistance grade of 10 and a Cobb60 value of 1.9 g/m 2, which was significantly lower than that of the control sample (25.7 g/m 2 ). In addition, the tensile energy absorption index (TEA*) was also improved from 17.6 to 123.4 J/g. Finally, coated Kraft paper was used to wrap burgers, fries, petit fours, etc., and the results showed excellent all-around performance, including barrier properties, mechanical strength, etc. The developed barrier technology has great potential in the food packaging industry.

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.
