Abstract: Understanding the nutritional quality and aroma composition of strawberry fruit has important guiding significance for the selection of strawberry varieties with high nutritional value and strong aroma. In this study, micro extraction-solid phase combined with GC-MS was used to analyze the changes of nutrient quality and aroma components in different developmental stages of strawberry. The results showed that the contents of anthocyanin, soluble sugar and vitamin C (VC) increased with fruit development. The aroma components of strawberry were composed of aldehydes, ketones, alcohols and esters. The main components were 2-hexenal (26.46%), 3,7-dimethyl 1.6 octadien-3-ol (15.96%), and 2-nerolidol (13.94%), etc. Among them, aldehydes content increased with fruit development; alcohols content was less in immature fruit, but increased sharply in mature fruit, up to 31.31%. Based on the aroma value (relative content/flavor threshold) of the main aroma components, it was speculated that the characteristic aroma of mature strawberry fruit were hexenal and furanone. The results of this study would provide a theoretical basis for strawberry quality control and the selection of new strawberry varieties.
