Abstract

The variation in lipidome of house cricket, banded cricket, Jamaican field cricket and two-spotted cricket was studied using high-throughput screening techniques for fingerprinting (MALDI TOF MS, GC-MS and LC MS-MS) and well-stablished chromatographic techniques for quantification (HPLC-ELSD, GC- FID). Although the four cricket species were reared in identical conditions, two-spotted & banded crickets had a lipid content 1.5 fold higher than house cricket. The lipids were high in UFA (>63%) and unsaturated TAG (>98%) making them liquid at room temperature, thus an oil. Cholesterol and several phytosterols were profiled finding high cholesterol concentration which is a point of concern. Eight phospholipid types (211 species) were identified with no major differences among cricket species. Using high-throughput screening techniques we demonstrate the complexity of cricket lipidome. Information on the lipidome of these crickets with high commercial value is important to estimate its nutritional value and their potential food applications.

摘要

采用高通量筛选技术（MALDI-TOF MS、GC-MS 和 LC-MS-MS）进行指纹分析和成熟的色谱定量技术（HPLC-ELSD、GC-FID）研究了家蟋蟀、带纹蟋蟀、牙买加田野蟋蟀和双斑蟋蟀的脂质组变化。尽管这四种蟋蟀在相同的条件下饲养，但双斑蟋蟀和带纹蟋蟀的脂质含量是家蟋蟀的 1.5 倍。这些脂质富含 UFA（>63%）和不饱和 TAG（>98%），使其在室温下呈液态，因此是油。胆固醇和几种植物甾醇的分析发现胆固醇浓度很高，这是一个值得关注的问题。鉴定了八种磷脂类型（211 种），蟋蟀种类之间没有明显差异。我们使用高通量筛选技术展示了蟋蟀脂质组的复杂性。这些具有高商业价值的蟋蟀的脂质组信息对于评估其营养价值及其在潜在食品中的应用非常重要。
