< 구두-E-13 > Potential of mineral oil migration from recycle paper based packaging into food
( Lisman Suryanegara Fitria ),( Dede Hy Yanto ),( Raden Pb Laksana ),( Yudhi D Kurniawan ),( Widya Fatriasari ),( Euis Hermiati ) 한국목재공학회 2018 한국목재공학회 학술발표논문집 Vol.2018 No.1
Food packaging is an important part in supporting food safety rules. The fact that not all of food packaging materials meet the requirements of food packaging materials, even primary, secondary, and tertiary packaging, cause the food in the packaging is potentially contaminated. One of the primary packaging materials is a duplex carton which is a product of recycled paper. Duplex carton is the most widely used primary material because of its cheaper and more eco-friendly. However, recycled paper is likely to contain printing inks, adhesives, waxes, fluorescent dyes and bleaches, fillers, organochlorine compounds, aromatic hydrocarbons, volatile organic compounds, barrier and oil-resistant materials, amines and surfactants. One of the hazardous substances contained in primary food packaging especially duplex carton is mineral oil or mineral oil hydrocarbon (MOH). Contamination of mineral oil into food packaging can be derived from printing ink contained on recycled paper or from printing ink on the packaging itself. Animal studies show that digestion of small amounts of mineral oil compounds can accumulate in the body and damage the liver and blood vessels in the heart, lymph nodes, and can be carcinogenic. This study aims to determine the potency of mineral oil migration from recycled paper-based food packaging. Migration test method that was used was the Federal Reference Laboratory for Food Contacts at the Federal Institute for Risk Assessment (BfR). Based on the analysis result both from internal standard adition at the beginning and at the end of the process showed that there is a potency of mineral oil to migrate from recycled paper based food packaging in this case is duplex carton.

Enzymatic Hydrolysis Performance of Biomass by the Addition of a Lignin Based Biosurfactant
( Widya Fatriasari ),( Fajar Nurhamzah ),( Rika Raniya ),( R. Permana Budi Laksana ),( Sita Heris Anita ),( Apri Heri Iswanto ),( Euis Hermiati ) 한국목재공학회 2020 목재공학 Vol.48 No.5
Hydrolysis of biomass for the production of fermentable sugar can be improved by the addition of surfactants. In pulp and paper mills, lignin, which is a by-product of the pulping process, can be utilized as a fine chemical. In the hydrolysis process, lignin is one of the major inhibitors of the enzymatic breakdown cellulose into sugar monomer. Therefore, the conversion of lignin into a biosurfactant offers the opportunity to solve the waste problem and improve hydrolysis efficiency. In this study, lignin derivatives, a biosurfactant, was applied to enzymatic hydrolysis of various lignocellulosic biomass. This Biosurfactant can be prepared by reacting lignin with a hydrophilic polymer such as polyethylene glycol diglycidylethers (PEDGE). In this study, the effect of biosurfactants on the enzymatic hydrolysis of pretreated sweet sorghum bagasse (SSB), oil palm empty fruit bunch, and sugarcane trash with different lignin contents was investigated. The results show that lignin derivatives improve the enzymatic hydrolysis of the pretreated biomass with low lignin content, however, it has less influence on the enzymatic hydrolysis of other pretreated biomass with lignin content higher than 10% (w/w). The use of biosurfactant on SSB kraft pulp can increase the sugar yield from 45.57% to 81.49%.
