檢測食品用二氧化碳中總硫/二氧化硫
檢測食品用二氧化碳中總硫/二氧化硫 詳細(xì)信息：


目前，在食品等行業(yè)廣泛使用二氧化碳作為防腐劑、致冷劑、萃取劑、保護(hù)性氣體或碳酸化劑。因為從防腐的角度講，二氧化碳能對微生物起作用是由于①二氧化碳分壓的增高，影響需氧微生物對氧的利用。②二氧化碳能終止各種微生物的呼吸代謝。③如果食品中存在大量二氧化碳，可改變食品表面的PH值，而使微生物失去生存的必需條件。二氧化碳對于多脂食品、乳制品、快餐食品、花生和其他對氧敏感的干制品的“抗氧化劑”作用和在貯藏環(huán)境中對水果、蔬菜及谷物呼吸作用影響均較其抗菌作用重要得多。在果汁、軟飲料、葡萄酒中的二氧化碳主要起防腐作用，此外它在軟飲料中還起清涼作用，阻礙微生物生長，致死嗜氧微生物，突出香氣賦以飲料，舒適的殺口感。現(xiàn)在廣泛用食品添加劑使用的二氧化碳產(chǎn)品對具有一定毒性、又可產(chǎn)生強烈異味的硫化物指標(biāo)控制極為苛刻。國際飲料技術(shù)學(xué)會、國家標(biāo)準(zhǔn)等對除二氧化硫外的總硫指標(biāo)的控制限為O. 1PPm，二氧化硫控制在1. OPPm。現(xiàn)行的硫化物分析方法包括氧化為庫倫法、紫外熒光法、硫化氫比色(色帶)法及火焰光度氣相色譜法等。

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.
