Chitin and chitosan is due to the effect of natural cationic polymers, have good curb microbial / bacterial / fungal action can be used in food preservation, food packaging chitin within specifications, toxic pollution would be made of chitosan After the cleaning solution is sprayed on the skin or peeling fruit, colorless and tasteless film offer aeration chitin chitosan stem formation, eating does not have to remove the film. Chitin governance role of indoor air using a special process in the product added silicon nano-silver coating evenly distributed in the inner and outer layers. Nanoscale silver ions can breakdown at low concentrations microbial cell membrane of bacteria, destruction of bacterial cells by controlling the activity of a variety of biochemical procedures prime pin, thereby enabling the bacteria can not breathe, metabolism, reproduction until death. But the cells are destroyed, inorganic nano silver ions and will not disappear chitin price, but will once again free from bacterial release, continue to work with other microorganisms, and cut off the role. So the cycle of killing mechanism, so that the coating can be a long time to maintain the antibacterial effect. Chitin manufacturers, Marvell Biotechnology (certified), chitin is provided by Shouguang Maiwei biotechnology company. Shouguang Maiwei Biotechnology Limited (www.maiweishengwu.com) Shandong Weifang, a leader in bio-fertilizer, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Marvell biotechnology leader in the staff warmly welcome all inquiries negotiations to create Marvell biotechnology a better future.
