15、uation 0 引 言 克氏原螯虾,又称龙虾、小龙虾,属甲壳纲十足目水生类动物,因肉质鲜美,深受人们的喜爱。小龙虾分布广泛,原产墨西哥、美国,20 世纪引入我国,现已经成为我国重要经济养殖物种。2020 年,我国的小龙虾总产值高达到3448.46亿元,其中小龙虾养殖业748.38亿元;以加工业为主的第二产业产值占比很低,约为 480.08 亿元1。小龙虾的加工以初级加工为主,即生产虾尾、虾仁等初级加工产品,导致其可食率很低,加工过程中产生的虾头、虾壳及内脏等废弃物含量高达 50%60%2,这些废弃物中也富含甲壳素、虾青素、氨基酸、钙、钠、钾、磷和微量元素硒等3,如果将这些废料中的营养元素充分
16、利用,必将带来巨大的经济效益。例如,朱继国等4利用克氏原鳌虾壳为钙源制备钙质补充;王紫微5利用虾头和虾壳酿造一种功能性调味料。但此类研究还不够全面,目前对于克氏原鳌虾营养价值的研究大多都集中在肌肉品质上,例如程小飞等6研究了不同养殖模式对克氏原鳌虾的肌肉品质影响,彭波等7研究了性别差异对克氏原鳌虾的肌肉及含肉率的影响,毛涛等8分析了不同规格及体色对克氏原鳌虾肌肉品质的影响。近年来,随着我国克氏原螯虾产业的快速发展,克氏原螯虾的营养价值也越来越受人们的关注。目前,对克氏原螯虾虾壳、肝胰腺等废弃物的营养价值研究较少,且没有关于性别和规格对克氏原鳌虾各部位营养价值影响的相关研究。因此,本研究将不同规格的克氏原鳌虾按性别分为 6 个大类,分析对比了不同性别及规格克氏原螯虾可食用部位(虾钳、尾部肌肉)与不可食用部位(虾头壳、肝胰腺)等部分营养成分之间的差异,为确定具体规格及性别克氏原鳌虾在食用方面的精细加工及虾壳、肝胰腺等废弃物的综合利用提供数据理论支持。1 材料与方法 1.1 材料与试剂 3 个规格的雌雄克氏原螯虾,购于湖北省武汉市南湖悦活里超市,活虾清洗干净后,用剪刀、钳子等工具解剖为虾头壳
