海膽(Paracentrotus lividus)卵對人類而言是一份頗受歡迎的佳餚。本研究中，不同季節裡海膽卵之產率、脂肪酸、胺基酸及一般組成被探討。平均產率為5.45±2.21%。蛋白質、粗脂肪、水分、灰分及碳水化合物含量分別為12.03±1.26%、3.05±0.50%、79.87±1.43%、2.25±0.24%及2.80±2.41%。其中，C16:0、C20:5n3及C22:2n6脂肪酸為重要脂肪酸；而主要胺基酸為麩胺酸（非必須，NE）、甘胺酸(NE)、離胺酸（必須，E）、天門冬胺酸(E)及精胺酸(NE)。必須/非必須胺基酸之比例為0.58±0.01；脂肪酸方面則富含多元不飽和脂肪酸。本論文斷定，海膽卵是不飽和脂肪酸、蛋白質及胺基酸等人類必要營養組成的豐富來源。

Sea urchin (Paracentrotus lividus) roes are popular delicacy to human. In this study, seasonal variations in the yield, fatty acid, amino acid and proximate compositions of sea urchin roe were studied. The average yield was 5.45±2.21%. Protein, crude fat, moisture, ash and carbohydrate contents were 12.03±1.26%, 3.05±0.50%, 79.87±1.43%, 2.25±0.24%, and 2.80±2.41%, respectively. The fatty acids of C16:0, C20:5 n3 and C22:2 n6 were the important fatty acids, whereas the major amino acids were glutamic acid (non-essential, NE), glycine (NE), aspartic acid (NE), lysine (essential, E) and arginine (NE). The E NE ratio was 0.58±0.01 and fatty acids were rich in PUFA. It was concluded that sea urchin roes are rich sources of unsaturated fatty acids, proteins and amino acids, which are the essential components of human nutrition.
