Research Progress on Application of Nisin in Food Storage and Preservation Based on Patent Analysis

As a kind of food additive with natural, high efficiency and safety, nisin was widely used in food storage and preservation due to its broad spectrum antibacterial activity against Gram-positive bacteria. This article reviews the patents of Nisin in the application of food storage and preservation based on the existing patent data and progress in techniques. It focuses on the current situation in patent application of Nisin from the aspects of single application, compound antiseptic, Nisin combined with physical technology, microencapsulation and antibacterial foodstuff packaging film. The results imply that enterprises should accelerate patent application in the hot research field, such as the synergistic antimicrobial activity of Nisin and other food additives, and rationally utilize invalid patent technology. Besides, they should avoid the risk of patent infringement and realize the high speed development of the Nisin application technology.
