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/m2, which was significantly lower than that of the control sample (25.7 g/m2). 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.

An enzyme-linked immunosorbent assay method was developed here for benzophenone (BZP) detection in package paper samples based on polyclonal antibody. 4-Aminobenzophenone (ABZP) was used as hapten and conjugated with bovine serum albumin for antibody production. Cross-reactivity results showed that the antibody can be recognised BZP, ABZP and Michler's ketone very well (IC50 value was 31.2±7.8 ng/mL, 35.9±8.3 ng/mL and 43.7±8.2 ng/mL, respectively). After optimisation of the effects from pH, ionic strength and organic solvents on immunoassay, we established a rapid method and used for BZP detection in fortified package paper samples with good recovery data (98.5 and 99.7%) at 100 and 600 ng/g spiked level.)

Global liquid packaging industry has been greatly spurred by the rapidly growing food & beverage industry all over the world. Liquid packaging board (LPB), as the main composition (75–80 %) of laminated liquid packaging cartons, must possess high-quality of hydrophobicity and physical properties for excellent leak-proof and protecting the packaged commodity. Herein, in this study, lignin is selected to prepare lignin cationic surfactant (LCS) by quaternary ammonium modification. Then cationic lignin modified rosin size ( L -CDRS) with uniform microsphere structure and high colloidal stability is successfully synthesized via a phase inversion process to improve the sizing performance and mechanical properties of LPB. The cation modified LCS presents improved amphipathicity of rich cationic charges and hydrophobic benzene ring skeleton, thus enhancing the electrostatic interactions between LCS and pulp fibers and improving the sizing performance of L -CDRS. The sizing performance of LPB is evaluated by varying the LCS dosages within L -CDRS and concluded that the edge penetration value and Cobb value of LPB handsheets exhibit an improved size performance with 2 % LCS within L -CDRS, implying the formation of homogeneous hydrophobic surface layer induced by the well-distribution of L -CDRS. In addition, the tensile index of LPB increased from 19.74 N·m/g to 25.96 N·m/g assisted by 2 % LCS emulsified L -CDRS, indicating an improved mechanical property. This study puts forward a practical and facile strategy to improve the sizing performance and mechanical properties facilitated by lignin enhanced rosin size and will further broaden the application range of traditional rosin size and lignin in LPB products.

Cellulose fiber-based food packaging papers with enhanced barrier and antibacterial properties were successfully fabricated by sequential deposition multilayers consisting of chitosan (CS) and carboxymethyl cellulose (CMC) on paper surface. The formation of CS/CMC multilayers on paper surface was systematically characterized. The CS/CMC multilayers effectively improved not only the barrier properties of papers against grease, oil, water, air and water vapor, but also the mechanical properties of papers. Moreover, the CS/CMC multilayer-modified papers showed improved antibacterial activities against E. coli and S. aureus . A (CS/CMC) 5 multilayer-modified paper exhibited the strongest antibacterial activity with growth inhibition rate of 95.8% against E. coli and 98.9% against S. aureus . No obvious cytotoxicity was detected for the obtained modified paper. Therefore, in consideration of its mechanical, barrier, antibacterial and safe performances, it is expected that the as-prepared cellulose fiber-based paper can be used as a promising material for food packaging.
