Difference in adsorbable organic halogen formation between phenolic and non-phenolic lignin model compounds in chlorine dioxide bleaching [PDF]

open access: yesRoyal Society Open Science, 2019
Adsorbable organic halogen (AOX) is generally formed by the reaction of residual lignin in pulps with chlorine dioxide during bleaching. Lignin has a complex structure. Different functional groups and bonds are present in lignin structures.

Chlorine dioxide gas treatment improves the quality of hardy kiwifruit (Actinidia arguta) during storage

open access: yesForest Science and Technology, 2019
The effects of gaseous chlorine dioxide fumigation treatment on the quality of Actinidia arguta “Daebo,” a hardy kiwifruit, were investigated. Hardy kiwifruit was fumigated with 30 mg L−1 chlorine dioxide gas for 30 min and stored at 2 °C for 5 weeks ...
