冷凍海鮮能保存多久？

現在的國家標(biao)準(zhun)是(shi)3個月，沒(mei)這個標(biao)準(zhun)之前通常是(shi)6個月，冰箱其實是(shi)一個很干(gan)燥的地方，海鮮存放久了(le)會脫水變質，所以(yi)冷凍海鮮還是(shi)應該盡(jin)早(zao)食用(yong)

“超標”凍海鮮可能對人有害

青島人喜歡吃海鮮，每年(nian)休漁期(qi)或是過年(nian)過節，市場(chang)上(shang)的(de)海鮮基(ji)本以凍(dong)海鮮為主，冷凍(dong)是否能讓海貨繼(ji)續“鮮”起來(lai)？

冷(leng)(leng)凍并不能確保海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)完全不變(bian)質(zhi)。一(yi)般(ban)冷(leng)(leng)凍海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)在穩定(ding)的(de)(de)-18℃時(shi)，其營養損失比較小，但前(qian)提條件(jian)必須(xu)是(shi)溫度一(yi)直處于(yu)穩定(ding)狀(zhuang)態(tai)。一(yi)旦運(yun)輸、儲存過(guo)程中溫度上升，冷(leng)(leng)凍海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)中的(de)(de)可溶性(xing)蛋白質(zhi)便會流失，并有(you)可能產生(sheng)多(duo)種氨(an)和硫化氫，使得海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)散發出(chu)異(yi)味，如(ru)果人(ren)一(yi)次性(xing)攝入過(guo)多(duo)，便有(you)可能造成(cheng)食物中毒，但至于(yu)是(shi)否會致(zhi)癌(ai)，還有(you)待科學考證。此外，雖然在長(chang)時(shi)間(jian)冷(leng)(leng)凍狀(zhuang)態(tai)下，能夠引起(qi)腐敗的(de)(de)微生(sheng)物處于(yu)不活動(dong)狀(zhuang)態(tai)，但海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)口感會受到(dao)影響，風味也會變(bian)差。如(ru)果不按(an)照標準任(ren)意延長(chang)冷(leng)(leng)凍海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)保質(zhi)期，則很有(you)可能造成(cheng)海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)變(bian)質(zhi)。食用(yong)對人(ren)體(ti)有(you)害。與冷(leng)(leng)凍海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)相(xiang)比，處于(yu)鮮(xian)(xian)(xian)(xian)(xian)(xian)活狀(zhuang)態(tai)下的(de)(de)海(hai)(hai)鮮(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)口感、營養水平是(shi)最好的(de)(de)。
