The strawberry, with its unique aroma, is one of the most popular fruits worldwide. The demand for specific knowledge of metabolism in strawberries is increasing. This knowledge is applicable for genetic studies, plant breeding, resistance research, nutritional science, and the processing industry. The molecular basis of strawberry aroma has been studied for more than 80 years. Thus far, hundreds of volatile organic compounds (VOC) have been identified. The qualitative composition of the strawberry volatilome remains controversial though considerable progress has been made during the past several decades. Between 1997 and 2016, 25 significant analytical studies were published. Qualitative VOC data were harmonized and digitized. In total, 979 VOC were identified, 590 of which were found since 1997. However, 659 VOC (67%) were only listed once (single entries). Interestingly, none of the identified compounds were consistently reported in all of the studies analyzed. The present need of data exchange between “omic” technologies requires high quality and robust metabolic data. Such data are unavailable for the strawberry volatilome thus far. This review discusses the divergence of published data regarding both the biological material and the analytical methods. The VOC extraction method is an essential step that restricts interlaboratory comparability. Finally, standardization of sample preparation and data documentation are suggested to improve consistency for VOC quantification and measurement.

我们对草莓香气的化学了解多少？

草莓具有独特的香气，是全球最受欢迎的水果之一。对草莓代谢新知识的需求在增加。这些知识适用于遗传研究，植物育种，抗性研究，营养科学和加工业。草莓香气的分子基础已经研究了80多年。迄今为止，已鉴定出数百种挥发性有机化合物（VOC）。尽管在过去的几十年中已经取得了相当大的进步，但草莓挥发物的定性组成仍存在争议。在1997年至2016年之间，发表了25项重要的分析研究。定性的VOC数据已统一并数字化。自1997年以来，总共发现了979种VOC，其中有590种。仅一次列出了659个VOC（67％）。有趣的是，在所有分析的研究中均未一致报告所鉴定出的化合物。当前在“组学”技术之间进行数据交换的需求需要高质量和健壮的代谢数据。到目前为止，尚无草莓挥发分的此类数据。这篇评论讨论了有关生物材料和分析方法的公开数据的差异。VOC提取方法是限制实验室间可比性的重要步骤。最后，建议对样品制备和数据文档进行标准化，以提高VOC定量和测量的一致性。当前在“组学”技术之间进行数据交换的需求需要高质量和健壮的代谢数据。到目前为止，尚无草莓挥发分的此类数据。这篇评论讨论了有关生物材料和分析方法的公开数据的差异。VOC提取方法是限制实验室间可比性的重要步骤。最后，建议对样品制备和数据文档进行标准化，以提高VOC定量和测量的一致性。当前在“组学”技术之间进行数据交换的需求需要高质量和健壮的代谢数据。到目前为止，尚无草莓挥发分的此类数据。这篇评论讨论了有关生物材料和分析方法的公开数据的差异。VOC提取方法是限制实验室间可比性的重要步骤。最后，建议对样品制备和数据文档进行标准化，以提高VOC定量和测量的一致性。VOC提取方法是限制实验室间可比性的重要步骤。最后，建议对样品制备和数据文档进行标准化，以提高VOC定量和测量的一致性。VOC提取方法是限制实验室间可比性的重要步骤。最后，建议对样品制备和数据文档进行标准化，以提高VOC定量和测量的一致性。
