Mixed Gas Carbon Monoxide - China

price: contact company for price

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is

slightly lighter than air. It is toxic to humans and animals when

encountered in higher concentrations, although it is also produced in

normal animal metabolism in low quantities, and is thought to have some

normal biological functions. In the atmosphere it is spatially variable,

short lived, having a role in the formation of ground-level ozone.

Carbon monoxide is used in modified atmosphere packaging systems in the US, mainly with fresh meat
products such as beef, pork, and fish to keep them looking fresh. The carbon monoxide combines with
myoglobin to form carboxymyoglobin, a bright-cherry-red pigment. Carboxymyoglobin is more stable
than the oxygenated form of myoglobin, oxymyoglobin, which can become oxidized to the brown
pigment metmyoglobin. This stable red color can persist much longer than in normally packaged meat.
Typical levels of carbon monoxide used in the facilities that use this process are between 0.4% to 0.5%.

The technology was first given 'generally recognized as safe' (GRAS) status by the U.S. Food and Drug
Administration (FDA) in 2002 for use as a secondary packaging system, and does not require labeling. In
2004 the FDA approved CO as primary packaging method, declaring that CO does not mask spoilage
odor. Despite this ruling, the process remains controversial for fears that it masks spoilage. In 2007 a bill
was introduced to the United States House of Representatives to label modified atmosphere carbon
monoxide packaging as a color additive, but the bill died in subcommittee. The process is banned in
many other countries, including Japan, Singapore, and the European Union.
