Abstract
The present disclosure discloses an antibacterial glucose-based composite nanoparticle and a processing method and use thereof, and belongs to the technical field of processing of modern food. According to the present disclosure, the antibacterial composite nanoparticle is prepared by using a particle surface positioning modification technology and a physical field charge transfer technology with a natural glucose-based nanoparticle as a raw material. The obtained antibacterial composite nanoparticle has a particle size of 50-1,000 nm, a surface zeta potential of 0 to −10 mV and a broad-spectrum antibacterial rate of greater than 98%. The shelf life of food can be effectively prolonged to prevent spoilage of products. The antibacterial composite nanoparticle can be used in food, textiles, daily chemicals, medicine and many other fields, and has a wide application prospect.
