STUDY ON SOME PROPERTIES OF BERBERINE ADSORBED 3D-NANO-CELLULOSE MEMBRANES FOR APPLICATION IN FRESH FOOD PACKAGING

Abstract

The use of 3D-nano-cellulose (3DNC) membrane, a biological polymer combined with berberine – an antimicrobial agent to fabricate materials with suitable properties in the packaging and preserving fresh food, is a new research direction. The study results showed that 3DNC membranes produced by Acetobacter xylinum in the standard medium (SM), coconut medium (CM) and rice medium (RM), after adsorbed berberine (B), to obtain the 3DNC-B membranes, all have properties suitable for use as the packaging and preserving fresh food. Water absorption capacities of all 3DNC membranes were not significantly different. The 3DNC-B membranes were durable and less permeable to water, cooking oils at room temperature and high temperature. Bacterial resistance of all 3DNC membranes were similar to nylon bags. 3DNC-B membranes have potential applications in fresh pork packaging and preservation; in which 3DNC-MTC-B and 3DNC-MTD-B membranes had sensory quality better than 3DNC-MTG-B membrane.
