Because a 40% of fish body of Skipjack tuna is now discarded, a method for effective utilizing is in great demanded. In this study, the value of the marrow and spine of Skipjack tuna as food was investigated. As a result of analyses of free amino acid content and amino acid composition, it was found that the marrow was rich in taurine, amino acid-related compound. The marrow was also rich in collagen. The elution and contents of substances containing amino groups in extract of the marrow and spine of Skipjack tuna reached a plateau by boiling for 15 min. However, the contents of umami-related products in the extract was very low. The several functionalities such as the antioxidative, anti-obesity, and anti-hypertensive activities were tested in vitro. Unfortunately, the noteworthy functionalities could not be recognized. Consequently, it was concluded that it is difficult to utilize the marrow and spine of Skipjack tuna as food material at present.

由于目前40%的金枪鱼鱼体被丢弃，人们迫切需要一种有效利用的方法。本研究对巨嘴金枪鱼的骨髓和脊椎作为食物的价值进行了研究。通过对游离氨基酸含量和氨基酸组成的分析，发现骨髓中含有丰富的牛磺酸，与氨基酸相关的化合物。骨髓中也含有丰富的胶原蛋白。沸腾15min，脊髓液和脊液中氨基物质的洗脱率和含量均达到平台期。然而，提取物中鲜味相关产品的含量很低。对其抗氧化、抗肥胖、抗高血压等功能进行了体外测试。不幸的是，这些值得注意的功能无法被识别。由此可见，目前还很难利用蓝鳍金枪鱼的骨髓和脊椎作为食物原料。
