At present, carbon dioxide is widely used as a preservative, a refrigerant, an extractant, a protective gas or a carbonating agent in food and other industries. Because from the perspective of anti-corrosion, carbon dioxide can act on microorganisms due to the increase in partial pressure of carbon dioxide, which affects the utilization of oxygen by aerobic microorganisms. 2 carbon dioxide can stop the respiratory metabolism of various microorganisms. 3 If there is a large amount of carbon dioxide in the food, it can change the PH value of the food surface, and make the microorganisms lose the necessary conditions for survival. The "antioxidant" effect of carbon dioxide on fatty foods, dairy products, fast foods, peanuts and other oxygen-sensitive dry products and the effects on the respiration of fruits, vegetables and grains in the storage environment are much more important than their antibacterial effects. Carbon dioxide in juices, soft drinks, and wines mainly acts as a preservative. In addition, it also acts as a cooling agent in soft drinks, hinders microbial growth, kills aerobic microorganisms, highlights aromas and gives a drink, and comfortably kills. Carbon dioxide products, which are now widely used in food additives, are extremely harsh in controlling sulphide indicators that are both toxic and have a strong odor. The limit of the total sulfur index of the International Beverage Technology Association and the National Standard for the removal of sulfur dioxide is O. IPPm, and the sulfur dioxide is controlled at I. OPPm.

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. used capillary column to determine the determination of sulfide in raw material carbon dioxide. The external standard method was used for quantitative determination. H2S/COS/SO2/CS2 was effectively separated and the results were satisfactory.
