为了探讨甜菜碱、糖原及无机盐含量对三疣梭子蟹肌肉口感品质的影响，采用可见分光光度法、蒽酮比色法和原子分光光度法，分别测定了3个发育阶段（8月份幼蟹阶段、10月份交配前和12月份交配后）的野生三疣梭子蟹肌肉组织中甜菜碱、糖原及无机盐含量。结果表明：1）肌肉中甜菜碱含量在第一阶段（8月幼蟹）甜菜碱含量最低，为172 mg/100 g，10月交配前雌蟹肌肉甜菜碱含量最高，达473 mg/100 g，但12月份交配后含量减半；雄蟹肌肉则表现为从第1到第3阶段逐渐升高趋势。2）幼蟹的糖原含量极低，仅为0.8μg/mg，交配前雌雄蟹仍保持较低水平，交配后糖原含量急剧升高，雌雄蟹分别上升至11.26μg/mg和9.61μg/mg，各是交配前的6.5倍和10倍。3）肌肉无机盐中K、Na是宏量元素，含量最高，K含量336～457 mg/100 g， Na含量131～185 mg/100 g，Fe为微量元素，含量最低，仅有1.12～1.26 mg/100 g。三疣梭子蟹肌肉中的甜菜碱含量远高于一般水产品，故蟹肉入口爽滑带有甜味，且随着肌肉中糖原含量不断增加，其风味也更佳。

In order to explore the effect of betaine , glycogen and inorganic ions on the mouthfeel of Portunus trituberculatus, the beta-ine, glycogen and inorganic ions of muscle tissue of wild Portunus trituberculatus at three different developmental stages (juvenile crabs in August, before mating in October and after mating in December ) were measured by spectrophotometry , anthrone colorimetric method and atomic spectrophotometry , respectively .The results showed that the contents of betaine in juvenile crabs were the lowest with 172 mg/100 g in August and the highest in female crabs before mating with 473 mg/100 g in October , but after mating , the contents of be-taine in female crabs halved;the contents of betaine in the male crabs′muscles increased gradually with the growth .The contents of glycogen in juvenile crabs were very low , just 0.8μg/mg.The glycogen of male and female crabs kept a lower level before mating , but increased rapidly after mating , the contents of glycogen in male and female crabs rose to 11.26 μg/mg and 9.61μg/mg, respectively. The elements of K and Na were macroelement and were highest in inorganic ions of muscles , the content of K was 336-457 mg/100 g, and the content of Na was 131-185 mg/100 g;Fe was microelement , only 1.12-1.26 mg/100 g.
