Detection of total sulfur/sulfur dioxide in carbon dioxide for food
Detection of total sulfur/sulfur dioxide in carbon dioxide for food use Details:


At present, carbon dioxide is widely used as preservative, refrigerant, extractant, protective gas or carbonation agent in food and other industries. Because from the perspective of anti-corrosion, the effect of carbon dioxide on microorganisms is due to the increase in the partial pressure of carbon dioxide, which affects the use of oxygen by aerobic microorganisms. ② Carbon dioxide can stop the respiratory metabolism of various microorganisms. ③If there is a large amount of carbon dioxide in the food, it can change the PH value of the food surface, and the microorganisms will lose the necessary conditions for survival. The "antioxidant" effect of carbon dioxide on fatty foods, dairy products, snack foods, peanuts and other oxygen-sensitive dry products and the effect on the respiration of fruits, vegetables and grains in the storage environment are much more important than its antibacterial effect. Carbon dioxide in fruit juices, soft drinks, and wine mainly acts as a preservative. In addition, it also acts as a cooling agent in soft drinks, hindering the growth of microorganisms, killing aerobic microorganisms, highlighting the aroma and giving the beverage a comfortable and killing taste. The carbon dioxide products that are widely used as food additives are extremely harsh on the control of sulfide indicators that have certain toxicity and can produce strong odors. The International Beverage Technology Society, National Standards, etc. have a control limit of 0.1PPm for total sulfur indicators other than sulfur dioxide, and sulfur dioxide is controlled at 1.OPPm. The current sulfide analysis methods include oxidation to coulometric method, ultraviolet fluorescence method, hydrogen sulfide colorimetric (ribbon) method and flame photometric gas chromatography.
