FABRICATION OF MULTIFUNCTIONAL MEMBRANES FOR FOOD PACKAGING TO REPLACE THE NYLON BAGS FROM 3D-NANO-CELLULOSE MATERIAL AND BERBERIN

Abstract

Study on the use of biopolymers and antimicrobial agents to fabricate the food packaging films is an eco-friendly solution and an option for sustainable development. Fabrication of multifunctional and eco-friendly 3DNC-B films from 3D-nano-cellulose material (3DNC) and berberin (B) for used to preserve food is a new research subject to prioritize investment and implementation. 3DNC is produced by Acetobacter xylinum in the standard medium (SM), coconut medium (CM) and rice medium (RM). 3DNC is adsorbed berberin having suitable properties for covering and protecting food. The tensile strength and elongation of 3DNC-SM and 3DNC-CM membranes are higher than the 3DNC-RM membranes. FE-SEM images showed that the fiber system of 3DNC-SM and 3DNC-CM membranes interleaves thicker than the fiber system of 3DNC-RM membranes. Testing using 3DNC-B covered the pork results in 3DNC-SM-B and 3DNC-CM-B membranes with pH values were lower than 3DNC-RM-B membranes. 3DNC membranes have potential applications in food packaging and preservation to replace the nylon bags.
