Abstract: the practical application principle of ultraviolet spectrophotometry is to judge substances according to the different absorption degree of ultraviolet rays by different substances. Because ultraviolet light has this characteristic, it can be applied to the judgment of substances. Food is the basis of people's life. For the composition detection and safety analysis of the produced food, it plays an important role in the process of food inspection and is of great significance to maintain food safety. Because UV spectrophotometry has the characteristics of simple operation and high sensitivity in practical application, it is widely used in food detection and safety analysis by food safety inspection departments. Based on this, this paper will stand on the application of UV Spectrophotometry in food detection and food safety analysis, explore the scope of application and practical results, and look forward to its future development space based on reality and combined with the development trend of the times.
Keywords: UV spectrophotometry; food testing; food safety analysis; expectation
紫外分光光度法操作簡單、應(yīng)用范圍較為廣泛，是目前用于檢測成分的常用方法之一。它廣泛應(yīng)用于各個(gè)領(lǐng)域，可以用于成分的定性、定量分析，尤其為成分定性中的檢測與分析。隨著時(shí)代的發(fā)展，經(jīng)濟(jì)力量的提升，人們?cè)絹碓阶⒅卦谟谑称钒踩珕栴}。因此，加強(qiáng)食品安全管理是保證時(shí)代向前發(fā)展的必要趨勢，因?yàn)槭称钒踩珕栴}一直是民生重要保障。對(duì)此，相關(guān)部門應(yīng)該加強(qiáng)對(duì)于食品安全的管理工作，保證食品健康安全。隨著一些食品安全問題的陸續(xù)曝光，食品安全問題受到社會(huì)各界的廣泛關(guān)注。我國目前主要存在的食品安全問題為一些非法添加劑的使用以及有害物質(zhì)超標(biāo)等問題。因此，下文將對(duì)紫外分光在食品檢測以及食品安全分析中的應(yīng)用展開具體分析。
1?對(duì)紫外分光光廣度法的基本介紹
紫外分光光廣度法在食品營養(yǎng)檢測以及食品安全的分析中的工作原理便是利用了不同事物在紫外可見光的分光光譜中的顯色度不同，利用此種特性進(jìn)行不同事物間的分辨。紫外分光光廣度法可以對(duì)不同物質(zhì)的定性與定量的分析，以及分析食品組成的結(jié)構(gòu)，借助顯色劑等鑒別物質(zhì)，對(duì)不同的物質(zhì)在特定化的檢測
