【正文】 在儀器上 45 分鐘可以得到結(jié)果。 在檢測技術(shù)上要有新檢測技術(shù)代替一些老的檢測方法。 唐雨德等應(yīng)用膠體金和免疫層析技術(shù)進(jìn)行了檢測金免疫層析法 (GICA)囊蟲循環(huán)抗原 (CA)試驗(yàn) , 結(jié)果表明 , 快速檢測囊蟲循環(huán)抗原的金免疫層析法具有簡便、快速、敏感、特異和穩(wěn)定的特點(diǎn) ,適合基層使用 [19]。例如 , Ramachandran(2020)等研制的自組裝蛋白質(zhì)微陣列可有效的避免蛋白質(zhì)的純化和芯片保存時(shí)的穩(wěn)定性等問題 , 從而使得一 步 法 完 成 蛋 白 質(zhì) 芯 片 的 制 作 成 為 可 能 ; 抗 體 噬 菌 體 展 示 技 術(shù)(Antibody phage display)的出現(xiàn)可大大縮短單抗的制備過程。 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 17 結(jié) 論 就我國食品安全的現(xiàn)狀來看, 食品安全存在著 如下 問題:消費(fèi)者對食品營養(yǎng)衛(wèi)生知識的認(rèn)識不夠;生產(chǎn)者對《中華人民共和食品安全法》不夠重視;監(jiān)管體系的不完善;檢測技術(shù)水平落后等。新的檢測技術(shù)縮短了分析時(shí)間、提高了分析的靈敏度、實(shí)現(xiàn)了在線分析、定性和定量分析、多種組分同時(shí)進(jìn)行分析等優(yōu)點(diǎn)。 有些檢測技術(shù)受到技術(shù)方面和其他方面的限制,不能被廣泛的應(yīng)用到食品分析行業(yè)。 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 18 謝 辭 感謝張老師 對我的論文修正工作的支持 ,并對本論文初稿進(jìn)行逐字批閱,指正出其中謬誤之處,使我 的論文整體有了很大的完善 。 通過本論文的寫作,我學(xué)到了很多知識,跨越了傳統(tǒng)方式下的教與學(xué)的體 制束縛,在論文的寫作過程中,通過查資料和搜集有關(guān)的文獻(xiàn),培養(yǎng)了自學(xué)能力和組織能力,并且由原先的被動的接受知識轉(zhuǎn)換為主動 的尋求知識,這可以說是學(xué)習(xí)方法上的一個(gè)很大的突破。 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 19 參考文獻(xiàn) [1] 高陽,楊薇,王佳江等 . 我國食品安全現(xiàn)狀 —— 問題及對策 . 中國食物與營養(yǎng) , 2020( 1): 1516 [2] 陳亞成,趙德明 .中國 食品安全現(xiàn)狀及其監(jiān)控體系的建立 . 《現(xiàn)代農(nóng)業(yè)科技》,2020( 9) : 281283 [3] 中華人民共和國食品安全法 .畜牧獸醫(yī)科技信息, 2020( 11): 1416 [4] 蔡支農(nóng),鄭豐杰 . 淺析我國食品安全現(xiàn)狀及其對策 , 科技創(chuàng)業(yè)月刊, 2020( 9) :8889 [5] 鄭豐杰.我國食品安全現(xiàn)狀及其對策.黃岡師范學(xué)院學(xué)報(bào), 2020( l2), 26( 6):7375 [6] 蔣士強(qiáng) , 陳萬金 . 食品安全保障體系建設(shè)與分析測試技術(shù) .現(xiàn)代科學(xué)儀器,2020 ( 1): 47 [7] 王多加,周向陽,金同銘等.近紅外光譜檢測技術(shù)在農(nóng)業(yè)和食品分析上的應(yīng)用.光譜學(xué)與光譜分析 Spectroscopy and Spectral Analysis, 2020( 4), 24( 4):447450 [8] 王海水,汪冬梅,席時(shí)權(quán) . 近紅外光譜在品質(zhì)分析和定量分析中的應(yīng)用 . 分析測試技術(shù)與儀器 , 2020( 9), 8( 3) : 136138 [9] 高榮強(qiáng),范世福.現(xiàn)代近紅外光譜分析技術(shù)的原理及應(yīng)用.分析儀器, 2020( 3): 912 [10] 蔣宏偉 , 李建華 , 姚敏杰 等.

Geic exchange is sprouting new varieties of bacterial strains with increased abilities to cause disease. The scientific munity must adopt a proactive approach, including an aggressive research agenda that seeks to determine the ecology of the food production and processing environments, as well as the basic biology of pathogenic anisms. In addition, it is crucial that we develop a wellintegrated educational strategy that seeks to educate industry and consumers. Issues Facing Food Safety When we examine the historical overview presented above, we conclude that there are three basic issues, which must be addressed in the ing century if we are to make an impact in the improvement of food satiety: our limited knowledge about food safety risks。 and limited educational efforts. Limited Knowledge of Food Safety Risks In considering the risks to food safety, we must think in terms of the food continuum from farm to table. Although much is known regarding how some anisms cause disease and how they are introduced into our food supply, we do not have a plete picture of how the practices that we employ from production to distribution impact the contamination of foods. For example, how do animal husbandry practices affect colonization with foodborne pathogens, as well as contamination of the farm environment? How do agents of disease interact with the animal host, and how do these interactions affect the ability of the animal to carry and/or spread these 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 22 anisms? In addition our knowledge of some of the basic science behind microbial behavior is limited. For instance, how do microanisms develop resistance to treatments designed to eliminate them? What environmental factors affect the emergence of new pathogens in nature? These and other unanswered questions are what stand in the way of our ability to proactively prevent future outbreaks since they are at the core of our ability to assess the risk that food production, processing, and preparation pose to food safety. Limited Application Of Effective Intervention Strategies In the past few years, several strategies have been developed and tested for the decontamination of animal carcasses at the slaughterhouse as well as strategies for the sanitation of fresh tits and vegetables. These strategies include anic acid rinses, hot water treatments, and steam pasteurization (Corry et al., 1995). However, the use of several of these strategies in bination has not been sufficiently elucidated. Moreover, the opportunity for recontamination of foods after treatment can occur, yet our strategies for minimizing such events are limited. If we are to impact the safety of our food supply, we need to use several strategies throughout the food continuum. For example, at the farm level, feeding regimens, type of feed used petitive exclusion, vaccine development, and geic manipulation could be employed to prevent colonization and shedding of pathogens from the intestinal tract of animals. In the case of tits and vegetables, practices used on the farm can impact the level and type of contaminant present on the crop (BeuchaL 1996). The type an
