| 摘 要： | 为了比较不同工艺制备的水产开口饵料中不同成分的溶失规律,试验对挤出滚圆法、挤出滚圆-流化床包衣法及膨化破碎法制备的饵料进行了质量损失率、粗蛋白溶失率、游离氨基酸(FAA)溶失率的比较研究,结果表明:膨化破碎工艺制备的开口饵料质量损失率、粗蛋白的溶失率和游离氨基酸的溶失率均高于挤出滚圆工艺;包衣没有明显改善饵料的溶失情况;游离氨基酸的溶失速度非常快,入水初期几乎全部溶失(5 min内溶失率就达到53.54%～91.71%)。

| Abstract: | In order to compare the characteristics of the aquatic micro-diets prepared by different processing methods,four micro diets were made by three methods(extrusion-spheronization,extrusion-spheronization and fluidized-bed coating,and expansion-breaking).The leaching rates of the diets' weights,the protein,and the free amino acid(FAA) were compared in this study.The results indicated that the three leaching rates of the diet made by expansion-breaking were all higher than by extrusion-spheronization;the effect... |
