本研究根据食物的种类分析了白斑金龟子Protaetia brevitarsis seulensis（Kolbe）的化学成分、脂肪、氨基酸，并通过禁食四天的方法进行了分析。体重损失由大到小依次为南瓜（0%）、芦荟（2.8%）、米糠（15%）和禁食（27%）。所有摄食幼虫的粗蛋白含量为50.7 ~ 55.4%，脂肪含量为16.1 ~ 18.5%。粗蛋白质和粗脂肪含量以米糠为最高。总脂肪酸中不饱和脂肪酸的含量在76.4%至75.5%的范围内。不饱和脂肪酸含量最高的是芦荟喂养的幼虫。在结构氨基酸中，必需氨基酸占36%，非必需氨基酸占34%。总多酚含量分别为23.57、23.38、23.05和22.7 mg g-1。米糠对ABTS、DPPH自由基的清除能力最强，分别为17.94 mg TEg-1和2.00 mg TEg-1。幼虫取食南瓜、芦荟、米糠和不取食的L值分别为72.3、64.7、58.3和44.3，以取食南瓜的最亮，禁食的最暗。这一结果表明，在加工前饲喂水果蔬菜比禁食白点金龟子幼虫更好。
This study analyzed the chemical composition, fat, and amino acids of the white-spotted flower chafers, Protaetia brevitarsis seulensis (Kolbe) according to the type of food, and It is not a bowel movement by fasting for four days. The loss of weight was increased in the order of food pumpkin (0%), aloe (2.8%), rice bran (15%) and fasting (27%). In all feeding larvae, crude protein content was in the range of 50.7 ~ 55.4% and fat content was 16.1 ~ 18.5%. The rice bran fed larvae showed highest content of both crude protein and fat. Unsaturated fatty acid content of the total fatty acid was in the range of 76.4 to 75.5%. The highest content of unsaturated fatty acid was measured in the aloe fed larvae. Among the structural amino acids, essential amino acid was 36% and 34% non-essential amino acids. The amount of total polyphenol were 23.57, 23.38, 23.05 and 22.7 mg g-1 in the larvae feeding bran, aloe, pumpkin, and fasting, respectively. ABTS, DPPH radical scavenging activity was the highest in the rice bran fed larvae with 17.94 mg TEg-1 and 2.00 mg TEg-1, respectively. L value indicating the lightness of larvae was 72.3, 64.7, 58.3 and 44.3 in the larvae feeding pumpkin, aloe, rice bran and nothing, respectively; the pumpkin fed one was the most bright and fasting one was the most dark. This result suggests that it is better feeding fruit vegetables than fasting the white-spotted flower chafers larvae before processing.
