SO2脱二氧化硫管 检测食品用二氧化碳中总硫/二氧化硫的详细资料
检测食品用二氧化碳中总硫/二氧化硫
检测食品用二氧化碳中总硫/二氧化硫 详细信息:
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极为苛刻。国际饮料技术学会、国家标准等对除二氧化硫外的总硫指标的控制限为O. 1PPm,二氧化硫控制在1. OPPm。现行的硫化物分析方法包括氧化为库伦法、紫外荧光法、硫化氢比色(色带)法及火焰光度气相色谱法等。

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.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a desulfurization tube for detecting total sulfur/sulfur dioxide in carbon dioxide for food, with satisfactory results.
