 Lớp màng không độc bao quanh bên ngoài bao toàn bộ khu cư trú từ bề mặt khối nguyên liệu nhằm hạn chế sự phát triển vi sinh vật bề mặt- một nguyên nhân chính gây thối hỏng thực phẩm. N- O carboxymethy (NOCC) được xử lý đặc biệt từ phản ứng của chitosan và monochloroacetic acid trong điều kiện kiềm, NOCC bị hòa tan trong dung dịch ở pH >6 hoặc pH

 non-toxic membrane surrounds the outside cover entire settlements from the block surface material in order to limit the development of microorganisms to the surface-a major cause of food spoilage rot. N-O carboxymethy (NOCC) are special treats from the reaction of chitosan and monochloroacetic acid in alkaline conditions, NOCC dissolves in solution at pH > 6 or Ph < 2. NOCC flexible membrane can form right in the water. This membrane has selective permeability of gases such as oxygen, carbon dioxide, but also have the ability to separate gas mixtures such as ethylene, ethane, acetylence. Study on the toxicity of NOCC shows in 50,000 ppm concentrations can cause dead mouse in 14 days. Likewise, studies in rabbits also points out that: the main road kind goes to the polymer in the blood is through the path of urine. However there is no more remarkable evidence is referred to again.

 nontoxic membrane surrounding the entire outer shell surface habitat from raw blocks to limit microbial growth substrate mat- a major cause of food spoilage. O carboxymethy N- (NOCC) is treated special from the reaction of chitosan and monochloroacetic acid under alkaline conditions, NOCC dissolved in solution at pH> 6 or pH <2. NOCC flexible membrane can be formed even in an aqueous solution there. This membrane has selective permeability gases such as oxygen, carbon dioxide, but also capable of separating gas mixtures such as ethylene, ethane, acetylence. Research on the toxicity of NOCC shows at 50,000 ppm concentrations can kill mice in 14 days. Similarly, studies in rabbits also showed that the main way to eliminate the polymer in the blood is via the urine. However no significant evidence than is mentioned again.
