What Do We Know about the Chemistry of Strawberry Aroma?
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
