            立足生活實踐,探究食品安全

                   201873日下午,浙江工商大學“慎毒篤法,明正景行”暑期社會實踐隊的隊員們在校內進行了食品檢驗實驗和食品粗加工實驗,親手探究辛香食品中罌粟殼含量并調查日常食品中亞硝酸鹽、農藥殘留物等含量狀況。

                   罌粟殼是罌粟的干燥成熟果殼,是制取鴉片的主要原料,也是多種鎮靜劑的來源。在國家發布的《食品中可能違法添加的非食用物質和易濫用的食品添加劑名單》中,罌粟殼名列其中。亞硝酸鹽外觀及滋味都與食鹽相似,在工業、建筑業中廣為使用,肉類制品中也允許作為發色劑限量使用,易引發食物中毒。在罌粟快速檢測實驗與亞硝酸鹽檢驗實驗前,余晨昊同學先介紹了兩種實驗的流程與細節,隨后隊員們針對調味粉、關東煮、火鍋底料、酸菜、辣條、泡菜、蘿卜干等日常食物有序開展實驗。

                   實驗過程中,隊員們不時發出驚嘆聲、感慨聲。好在實驗結果表明,檢測的絕大部分日常食品中的罌粟殼含量與亞硝酸鹽含量均在安全標準范圍內。這一結果使隊員們都露出了微笑,放下了心。實踐隊隊員曹佳丹同學在實驗結束后說道:“沒做實驗之前,聽別人說火鍋里會加罌粟殼我都嚇得不敢吃,現在看來去正規店家吃是沒有問題的。”

                   接著進行的是農藥殘留檢驗實驗。沒有被分解而殘留的農藥進入糧食、蔬菜、水果、魚、蝦、肉、蛋、奶等食物中,造成食物污染,極易危害人體健康。本次實驗選取的材料是生活中經常食用的菠菜、青菜、生菜等。令人欣喜的是,實驗結果顯示大部分蔬菜的農藥殘留量相對較低。

                   檢驗實驗結束后,隊員們領取制作壽司的基本食材和物料,躍躍欲試。更有隊員自備紫薯餅的相關材料,嘗試制作低卡環保紫薯餅。現場熱火朝天,隊員們在親自動手制作食物的過程中紛紛表示自制食物更放心,更健康。

                   通過此次的檢測實驗和食品粗加工,實踐隊成員紛紛表示對罌粟殼、亞硝酸鹽以及農藥殘留有了更為深刻的認識。超標的罌粟殼成分和長期、大量食用亞硝酸鹽會給人體造成極大傷害,因此在國家加強監管的基礎上,在日常生活中也要盡量減少食用腌制產品或儲存期較長的食物,避免亞硝酸鹽中毒。浙江工商大學“慎毒篤法,明正景行”暑期社會實踐隊立足于與日常生活關聯性更強的實踐,努力發揚法科學子求真務實、篤法慎行的精神,在禁毒事業中貢獻屬于我們的更有價值的力量。
