Analysis of Volatile Substances and Quality of 3 Different Fruit Types of Tomatoes
[Objective]To explore the differences in volatile compounds in taste tomato fruits with different fruit types.[Method]This study used headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry(GC-MS)to determine the volatile compounds in three types of fresh tomato fruit with different taste,including cherry tomatoes(4 varieties),strawberry tomatoes(4 variet-ies),and large fruit tomatoes(2 varieties),and conducted quantitative analysis.In addition,the lycopene and dry matter contents of 10 tomato fruit quality indicators were measured and analyzed,and conducted on the potential relationship between volatile substances and quality indicators of a correlation analysis.[Result]A total of 81 volatile compounds were detected in the tomato fruits of the 10 tested varieties,consisting of 10 alcohols,9 aldehydes,11 esters,7 ketones,33 hydrocarbons,and 11 other volatile substances,and all of them were all mainly composed of aldehydes,esters,hydrocarbons,and other compounds,accounting for over 78%of the total volatile substances.The number of volatile component fraction in cherry tomatoes was the most,with 70 species,and its total content is the highest.The volatile components of medium fruit tomatoes are 59 species,while those of large fruit tomatoes are 58 species.There are a total of 25 volatile components in the three types of taste tomatoes,and their content varies greatly among varieties.The content of lycopene in taste tomato ranged from 52.54 mg/100 g to 135.85 mg/100 g,which was different in different fruit types.The dry matter content ranges from 5.75%to 10.66%,with significant differences among different fruit types.Among them,cherry tomatoes have the highest dry matter content,followed by strawberry tomatoes,and large fruit type taste tomatoes have the lowest dry matter content,less than 6%.[Conclusion]The correlation analysis between quality indicators and volatile substances showed that geranyl Linalool and farnesyl acetone were significantly negatively correlated with Lycopene and dry matter,while dry matter was significantly positively correlated with cis-3-hexenal.There was no significant correlation between lycopene and dry matter content,and there was a certain correlation between volatile substances.
