我国六个产地卤虫初孵无节幼体的营养价值

对我国六个地区（河北沧州，河北黄骅，山东无棣，西藏措勒，内蒙锡林浩特，新疆巴里坤湖）所产卤虫初孵无节幼体的营养组进行了测定。结果表明，六个产地卤虫初孵无节幼体的蛋白含量为46％－53％，脂肪含量为21％－26％，除色氨酸因酸水解未测定之外，六个产地卤虫的无节幼体均含有17种氨基酸，氨基酸总量为干重的38％－445，必需氨基酸占氨基酸总量的48％－50％，六个产地卤虫无节幼体均含有较多的20：5n-3,18:3n-3含量很少，为海水型卤虫，其脂肪酸组成因产地而异，其中18:2n-6和20:5n-3的含量受产地的影响最大，西藏措勒的50:5n-3含量最高，达23．52％，内蒙锡林浩特最低为7．90％，六个产地卤虫的无节幼体均缺乏22：6n-3.

Nutritional value of new hatched Artemia na uplii of six geographic strains in China

The nutritional value of new hatched Artemia nauplii of six geographic strains ( CangZhou, HeBei; HuangHua.HeBei; WuDi, ShanDong; CuoLe, Tibet; XiLinHaoTe, Inner Monglia; BaLiKun Hu,XinJiang) in China was examined. The protein contents of the nauplii were 46% - 53% of dry weight , and the lipid contents were 21% - 26% of dry weight. 17 kinds of amino acids of the nauplii were detected. The content of total amino acids was 38% - 44% . The percentages of the essential amino acid in total amino acid were 48% - 50% . The six strains nauplii contained abundant 20: 5n - 3 and a small amount of 18: 3n - 3. They were marine type. Compositions of the fatty acid were different among Artemia nauplii of the different strains. The contents of 18:2n -6 and 20:5n - 3 were significantly affected by producing area. The contents of 20:5n - 3 from Cuole, Tibet and Xilinhaote, Inner Monglia were 23.52% and 7.90% respectively ,which were the highest and the lowest in the six strains. 22: 6n - 3 was not detected in the strains.
