Research progress of new materials in modified atmosphere packing of fresh foods

In the past few years, with people's cognition of their nutritional function the consumption of fresh and fresh-cut produces has increased sturdily.In order to adopt to this trend, it is an important way to develop effective post harvest storage and packaging technology, in addition to increasing production. Modified atmosphere packaging ( MAP) possesses a potential to become one of the most appropriate technologies, it has advantages of extending the shelf-life, preserving or stabilizing the desired properties of fresh produces, and convenience in handing and distribution.The success of MAP-fresh foods depends on many factors including types of fresh foods, storage temperature and humidity, gas composition, and the characteristics of package materials.This paper reviewed the recent developments highlighting the antioxidant active film, the nano packaging film and the biodegradable film.Although the innovations and development of food packaging technology will continue to promote the development of novel MAP, concentrated research and endeavors from scientists and engineers are still important to the development of MAP that focuses on consumers' requirements, enhancing product quality, environmental friendly design, and cost-effective application.
