海参肽类产品的腥味及滋味问题是影响其商品价值的重要因素。从发酵去腥角度出发,通过正交试验优化了乳酸菌发酵海参酶解液的制备条件,并探讨了发酵前后风味成分种类与含量差异。正交试验结果表明,在发酵时间7 h,蔗糖添加量为4%(质量分数),混合菌液[V(鼠李糖乳杆菌)∶V(嗜酸乳杆菌)=3∶1]接种量为3%的条件下,海参发酵液的感官评价值最高,即发酵效果最佳。顶空固相微萃取结合气相色谱-质谱分析结果表明,经过发酵呈不愉快气味的挥发性化合物由10种降为6种,化合物占比由发酵前的12.65%降低为发酵后的6.36%。呈愉快气味的挥发性化合物由18种增加到33种,占比由发酵前的31.46%上升至44.03%。通过冷冻干燥技术制备了富含乳酸菌的海参肽冻干粉,该冻干粉无腥味,具有海参的鲜味和发酵产生的良好风味。

额尔古纳地块东缘韩家园子‒富林地区紧邻蒙古‒鄂霍茨克缝合带,其广泛出露的早侏罗世‒早白垩世火成岩对于完善蒙古‒鄂霍茨克洋俯冲‒闭合历史具有重要意义.本文对韩家园子‒富林地区的中生代火成岩进行岩相学、锆石U-Pb年代学、全岩主‒微量元素地球化学研究.LA-ICP-MS锆石U-Pb结果显示韩家园子钾长花岗岩锆石U-Pb年龄为196±2 Ma,代表其侵位时代为早侏罗世;富林地区光华组粗安岩锆石U-Pb年龄为122±2 Ma,暗示其结晶时代为早白垩世.早侏罗世钾长花岗岩为准铝质的I型花岗岩,Mg^(#)值较低(36),Nb/Ta比值(16.55~17.05)接近于原始地幔,暗示岩浆应来源于新生下地壳的部分熔融.同时,钾长花岗岩富集大离子亲石元素Rb、Ba、K,亏损高场强元素Nb、Ta、Ti,与典型弧型火成岩的地球化学特征相一致,结合区域上发育同时代准铝质或弱过铝质I型花岗岩的事实,表明其可能与蒙古‒鄂霍茨克洋南向俯冲至额尔古纳地块有关.相比较下,早白垩世粗安岩具有较低的SiO_(2)含量(59.67%~59.93%)和较高的Mg^(#)值(42~43),同时富集大离子亲石元素Rb、Ba、K,亏损高场强元素Nb、Ta、Ti,富集Sr,亏损Th,暗示其可能是富集岩石圈地幔重熔的产物.鉴于区域上其他来源于富集岩石圈地幔的早白垩世钙碱性火山岩呈面状分布的特征,以及早白垩世A型花岗岩和变质核杂岩的存在,暗示粗安岩为蒙古‒鄂霍茨克洋闭合后伸展环境下的产物.结合区域最新火成岩和沉积岩资料,认为蒙古‒鄂霍茨克洋在早侏罗世‒早白垩世发生俯冲‒碰撞‒后碰撞作用,其在大兴安岭北部闭合时间应介于晚侏罗世末期和早白垩世早期(约150~140 Ma).
