Title: Innovations of Lijuan Wang in Food Packaging Technology

Introduction

Lijuan Wang is an accomplished inventor based in Harbin, China. He has made significant contributions to the field of food packaging technology, holding three patents that address critical issues in food preservation and safety. His innovative approaches have the potential to revolutionize how food is packaged and stored.

Latest Patents

One of Lijuan Wang's latest patents is the "Preparation method of high-barrier antibacterial flame-retardant food packaging film." This invention addresses the shortcomings of existing food packaging films, which are often non-degradable and flammable. The preparation method involves blending chitosan quaternary ammonium salt with phytic acid to create a polyelectrolyte complex. This complex is then added to a polyvinyl alcohol solution, which is heated to form a film. The resulting food packaging film exhibits impressive properties, including water vapor permeability and oxygen permeability, along with a limiting oxygen index (LOI) that ensures safety during use.

Another notable patent is the "Press-sealing method of anionic polysaccharide films." This method aims to resolve the challenges associated with sealing polysaccharide films into bags. The process includes preparing a chitosan quaternary ammonium salt solution and applying it to the sealing area of two anionic polysaccharide films. The films are then pressed under specific conditions to achieve a strong seal. This innovation is particularly useful for packaging food items like beef tallow, effectively extending their shelf life.
