Chemical analysis and genotoxicological safety assessment of paper and paperboard used for food packaging.
This study presents the research on the chemical analysis and genotoxicity of 28 virgin/recycled paper products in food-contact use. In the chemical analysis, paper products were extracted by reflux with ethanol, and analyzed by gas chromatography/mass spectrometry. 4,4'-bis(dimethylamino)benzophenone (Michler's ketone: MK), 4,4'-bis(diethylamino)benzophenone (DEAB), 4-(dimethylamino)benzopheno...
متن کاملDeveloping Hydrophobic Paper as a Packaging Material Using Epicuticular Wax: A Sustainable Approach
There is an urgent need for a biodegradable, hydrophobic material that can be used in developing packaging materials. In this preliminary study, epicuticular wax has been extracted from the leaves of Calotropis procera and Alstonia scholaris using various solvents (i.e., ethanol, methanol, benzene, and acetone). The highest wax amounts were found to be 0.54 μg/cm2 and 0.13 μg/cm2 from Alstonia ...

متن کاملComputer Usage and Demand for Paper / Paperboard Products
The purpose of this paper is to analyze the effect of computer usage on the demand for paper and paperboard products. A log-linear model is developed to analyze the effect of computer usage on the demand for four categories of paper, newsprint, printing/writing paper, packaging paper and household/sanitary paper. The analysis is divided into two parts. The first part is US monthly analysis. We ...
متن کاملEvaluation of the Coagulation and Flocculation Process Using Plantago major L. Seed Extract as a Natural Coagulant in Treating Paper and Paperboard Industry Wastewater
Introduction: Paper and paperboard industry wastewater has potentially damaging effects on the ecosystem of the receiving environments due to the presence of toxic compounds. As a result, the treatment of such wastewater is necessary prior to discharge into the environment. In this study, the potential of Plantago major L. seed extract as a natural coagulant in treating paper and paperboar...
