Abstract
台灣近年來因國人生活水準提高,飲食習慣也產生重大的變化。在健康意識抬頭下,天天蔬果579已成為大家耳熟能詳的口號。然而在這口號的背後卻潛藏著危機。蔬果最常見的健康殺手問題包括:買到囤積過久不新鮮的蔬果、蟲卵殘留、農藥殘留、硝酸鹽過量。其中以農藥殘留問題,對人體健康影響最大,嚴重者甚至會出現全身抽搐、昏迷、心臟衰竭和死亡。所以在食用前的清洗工作變得格外重要!
目前市面上清洗蔬果的產品都以界面活性劑為主,洗後仍有殘留的問題,因此本實驗為探討納米離子水利用電荷結合農藥的方式將蔬果中農藥去除,再利用多重殘留分析方法比較清洗前後農藥殘留濃度之差異,試驗結果提供未來一般民眾日常蔬果清洗之選擇。
本實驗以噴灑及浸泡兩種方式進行蔬果農藥殘留之去除,分別以納奈米離子水(1倍、10倍、100倍、500倍稀釋)、自來水與其他市售兩種蔬果洗潔劑進行試驗,而實驗時間分別為噴灑水果(小蕃茄、葡萄)作用1、2、5分鐘,以及浸泡蔬菜(青江菜、甜椒)1、2、5、30分鐘,清洗完後,再進行統計分析。結果顯示蕃茄與葡萄在噴灑稀釋500倍的納米水後,一分鐘皆有顯著降低農藥殘留率。青江菜在浸泡稀釋500倍的納米水(pH=10)中30分鐘後,農藥清除效果最佳。而甜椒在浸泡稀釋100倍的納米水中5分鐘後,顯著降低農藥殘留率。
