目前，在食品等行业广泛使用二氧化碳作为防腐剂、致冷剂、萃取剂、保护性气体或碳酸化剂。因为从防腐的角度讲，二氧化碳能对微生物起作用是由于①二氧化碳分压的增高，影响需氧微生物对氧的利用。②二氧化碳能终止各种微生物的呼吸代谢。③如果食品中存在大量二氧化碳，可改变食品表面的PH值，而使微生物失去生存的必需条件。二氧化碳对于多脂食品、乳制品、快餐食品、花生和其他对氧敏感的干制品的“抗氧化剂”作用和在贮藏环境中对水果、蔬菜及谷物呼吸作用影响均较其抗菌作用重要得多。在果汁、软饮料、葡萄酒中的二氧化碳主要起防腐作用，此外它在软饮料中还起清凉作用，阻碍微生物生长，致死嗜氧微生物，突出香气赋以饮料，舒适的杀口感。现在广泛用食品添加剂使用的二氧化碳产品对具有一定毒性、又可产生强烈异味的硫化物指标控制为苛刻。饮料技术学会、标准等对除二氧化硫外的总硫指标的控制限为O. IPPm，二氧化硫控制在I. OPPm。

Model: HH-Sulfur-30
Application: H2S/COS/SO2/CS2 determination

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.
