"水溶液氣味,味道及外觀"是食品級二氧化碳產(chǎn)品中一項極其重要的感官評價指標,在GB 10621-2006標準中,它是對質量要求中已量化的及未明確限定的雜質給出一個綜合的終端限制.二氧化碳產(chǎn)品的主要原料來自于各種工業(yè)廢氣及地下氣井,不同的生產(chǎn)原料和生產(chǎn)工藝生產(chǎn)的二氧化碳產(chǎn)品中,產(chǎn)生異味的物質不同,感官的味道亦差別很大.如:油的味道多源于烴類雜質的;醇類,醛,醚類等含氧有機物會呈現(xiàn)淡淡的酒香及甜味;硫化物則有著強烈的惡臭及腐味.在硫化物以總硫方式控制合格的前提下,發(fā)酵尾氣回收的二氧化碳產(chǎn)品中可能產(chǎn)生異味的雜質通常為醇,醛,醚,酮,酯等含氧有機物.當"水溶液氣味,味道及外觀"檢驗不合格時,應通過儀器分析確定"異味源",并給出定量分析結果,以免因為人的感觀差異而導致對檢測結果產(chǎn)生異議.另外針對發(fā)酵尾氣原料,在建議二氧化碳提純工藝時,要考慮對未知有機物的去除,確保生產(chǎn)出合格的產(chǎn)品.

浩瀚色譜（山東）應用技術開發(fā)有限公司，采用GDX-104填充柱測定食品級二氧化碳中氯乙烯，乙醛，環(huán)氧乙烷，甲醇和苯，柱效高，分離好，面積外標法定量，結果滿意。

"Aqueous solution smell, taste and appearance" is an extremely important sensory evaluation index in food-grade carbon dioxide products. The main raw materials of carbon dioxide products come from various industrial waste gas and underground gas wells. In carbon dioxide products produced by different production raw materials and production processes, the substances that produce peculiar smells are different, and the sensory tastes are also very different. For example: oil The taste is mostly derived from hydrocarbon impurities; oxygen-containing organic compounds such as alcohols, aldehydes, and ethers will present a faint wine aroma and sweetness; sulfides have a strong stench and rot. On the premise that the impurities that may produce peculiar smell in carbon dioxide products recovered from fermentation tail gas are usually oxygen-containing organic compounds such as alcohols, aldehydes, ethers, ketones, and esters. Determine the "odor source", and give the quantitative analysis results, so as to avoid objection to the test results due to the difference in human perception. In addition, for the fermentation tail gas raw material, when recommending the carbon dioxide purification process, the removal of unknown organics should be considered to ensure that Produce qualified products.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses GDX-104 packed column to determine vinyl chloride, acetaldehyde, ethylene oxide, methanol and benzene in food-grade carbon dioxide, with high column efficiency, good separation, and area external standard method for quantification, Satisfied with the results.
