本研究比较了韩国五个商业昆虫养殖场生产的白斑金龟子（Protaetia brevitarsis）幼虫的营养成分。幼虫的饲料来源如下：农场A，发酵的橡木锯屑;农场B，发酵的橡木和灌木锯屑;农场C，商业饲料;农场D，私人发酵饲料;和农场E，蘑菇堆肥的副产品。不同昆虫养殖场的干燥产率差异显著，范围为14.12%-27.28%。而幼虫干粉的含水量只有很小的差异（5.14- 7.38g/100 g）（p<0.001）。A、B和D场的仔鱼蛋白质含量高于C场和E场（p <0.05），脂肪含量低于C场和E场（p<0.05）。无论是在昆虫养殖场，总氨基酸和必需氨基酸含量没有显着差异。磷酸丝氨酸，牛磺酸，γ-氨基丁酸，众所周知的生理有用的化合物，检测到游离氨基酸的形式。脂肪酸组成以油酸、棕榈酸、棕榈油酸和亚油酸为主。养殖场A、B和E的幼虫油酸含量高于养殖场B和C的幼虫（p<0.05）。此外，来自农场A的幼虫呈现最低的饱和脂肪酸（SFA）/不饱和脂肪酸（乌法）比率。虽然营养成分差异的潜在机制尚未明确，本研究表明，农场A生产系统，只使用橡木饲料，可能是潜在的有益的，在增加蛋白质含量和降低SFA/乌法比在短拟步行虫幼虫。
This study was conducted to compare the nutritional composition of white-spotted flower chafer (Protaetia brevitarsis) larvae produced from five commercial insect farms in Korea. The feeding sources of larvae were different as follows: Farm A, fermented oak sawdust; Farm B, fermented oak and scrub sawdust; Farm C, commercial feed; Farm D, private fermented feed; and Farm E, byproduct from mushroom compost. Drying yield significantly varied by insect farm, ranging from 14.12% to 27.28%. However, there was only small difference (5.14–7.38 g/100 g) in moisture content of dried larvae powder (p<0.001). The larvae produced from Farm A, B, and D presented higher protein content and lower lipid content compared to those from Farm C and E (p<0.05). No significant differences in total and essential amino acid contents were found, regardless of the insect farms. Phosphoserine, taurine, and gamma-aminobutyric acid, well-known physiological useful compounds, were detected in form of free amino acids. The major fatty acids in the P. brevitarsis larvae were oleic acid, palmitic acid, palmitoleic acid, and linoleic acid. The larvae from Farm A, B, and E exhibited higher oleic acid content than those from Farm B and C (p<0.05). Moreover, the larvae from Farm A presented the lowest saturated fatty acid (SFA)/unsaturated fatty acid (UFA) ratio. Although the underlying mechanisms of the nutritional composition differences are not yet clearly understood, this study suggests that the Farm A production system, using only oak feed, could be potentially beneficial in increasing the protein content and decreasing SFA/UFA ratio in P. brevitarsis larvae.
