宁波口岸1-7月三文鱼进口量已超去年全年

2017-08-21 18:40:29   央广网

央广网宁波8月21日消息(记者杜金明 通讯员李锦华储星星 舒林军)宁波检验检疫局日前通报,今年1-7月,宁波口岸共进口三文鱼292.7吨,货值235.75万美元,进口量和货值双双超过2016年总和,创下进口量新高。

据了解,宁波口岸进口三文鱼均为冷冻产品,且90%以上来自智利,另有少部分来自阿根廷、越南等国。智利地处南美洲西南部沿海,海水纯净、温度适宜,具有三文鱼养殖得天独厚的条件,非常适合三文鱼生长,是世界第二大三文鱼养殖国家,因此三文鱼养殖量和出口量位居全球前茅,智利也是中国最大的冷冻三文鱼进口国。

三文鱼,学名大西洋鲑(Oncorhynchus),口感丰腴、味道鲜甜、肉质肥美,特有的橘色或橙色鱼肉能极大地刺激食欲,更因含有丰富的不饱和脂肪酸、维生素D等营养元素,被誉为“美容佳品”“抗衰老神药”。不论网传的三文鱼营养价值和保健功效准确与否,三文鱼作为最受吃货欢迎的海鲜产品是毋庸置疑的,“冰海之皇”的美誉也并不为过。

三文鱼的吃法多样,烟熏三文鱼、三文鱼刺身、蜜汁三文鱼、香煎三文鱼……最有名的无疑是“三文鱼刺身”了,三文鱼口感温和清爽,有着肥厚肌间脂肪层,鱼腩更是滑嫩肥美,既适合刺身又可以捏寿司,短短数十年间迅速走红,俘获了众多粉丝的心。

说到海鲜刺身,部分市民会有食品安全卫生方面的担心。野生捕捞鲑鱼类必须经过急冻才能用于生食,完全使用人工颗粒饲料喂食的鲑鱼可以直接生食。因为野生鲑鱼主要捕食小型鱼类和甲壳生物,存在寄生虫的传播途径。而完全使用人工颗粒饲料的养殖鲑鱼,其饲料经过高温处理,可以阻断寄生虫的传播途径。养殖三文鱼使用颗粒饲料喂养,而且正规途径进口的鲑鱼通常都按规定进行低温急冻处理(零下35摄氏度冷冻15小时或者零下23摄氏度冷冻一周),并通过零下18摄氏度以下的冷冻集装箱运输进境,人工养殖的三文鱼网箱上还架有隔离鸟类的设施,阻断了寄生虫通过鸟粪传播的途径,所以安全系数更高,生食相对安全。即便如此,欧美政府机构也并不赞成民众直接生食新鲜鱼肉,一般建议加热到63℃以上。因为生吃时海鲜中的硫胺素酶能破坏食物中的维生素B1;其次,适度加热不仅不会使三文鱼中的蛋白质、不饱和脂肪酸受到破坏,反而更有利于蛋白质的消化吸收。脾胃虚弱、过敏体质、痛风、高血压患者及孕妇,还是应当尽量避免生食三文鱼,若食用后出现胃部不适、腹泻等症状,应及时就医。

那么如何才能选购放心的三文鱼?检验检疫局的工作人员给出了几点建议:首先,要选择正规超市进行采购,正规超市对进口水产品的品质及资质的要求较高,在食品安全上更有保证;其次,查看产品证书,正规渠道进口的水产品应有检验检疫机构颁发的《入境货物检验检疫证明》,该证明中有产品的品名、生产日期、进口数量、原产国等信息,尤其是要注意该证书的品名,如果写是大西洋鲑鱼则更为可靠;第三,选购时也要“望、闻、按”,望:正宗三文鱼的颜色是粉红色偏橘色,如果那些红得非常鲜艳的就要当心了,很可能是虾红素染色的虹鳟冒充的。新鲜的三文鱼色泽非常亮,拿到阳光下还会折射出光线。观察颜色与条纹,大西洋鲑鱼的颜色偏橙黄色,表面的白色花纹数量更多且更清晰,肉质肥嫩口感绵软;如果三文鱼颜色变白,那就是变坏了;闻:刺身三文鱼闻一闻,如果能闻到明显的腥味就表示已经不新鲜了;按:三文鱼肉质紧实且富有弹性,新鲜的三文鱼鱼鳃呈鲜红色,鱼眼清澈,手指按下去,鱼肉会马上弹起来,口感结实饱满,有入口即化之感。如果不新鲜,按下去,鱼肉就会凹下去。另外,从超市买回的三文鱼最好当天就吃掉,这时的味道最鲜美。
